Visiting Jo O'Connell, plant maven from down under

As you may remember, I went on a quick road trip to Southern California right after Thanksgiving. One of the stops I was most looking forward to was Australian Native Plants nursery in Casitas Springs just outside of Ventura.

Few people in the U.S. know more about plants from down under than Australia-born horticulturist Jo O'Connell. She started the nursery in the early 1990s with her American husband Byron Cox and, through passion, dedication and perseverance, has developed it into a leading resource for plant material from the southern hemisphere. Much of the plants Jo and Byron offer are propagated by themselves, either from their own stock or from seeds imported from Australia. Literally, they are often the only source for a particular plant in the entire U.S. As you can see here, their plant list is truly impressive.

Jo O'Connell's personal story reads like a movie script—if Hollywood made movies about plant people, that is.

Weekend Wrapup (WeWu) for 3/10/19: rain, flowers, and foliage

As I'm typing this, the sky is much darker than it should be at 5:00 pm, and the rain has started to fall. I don't even bother looking at the forecast any more. Just like I'm sure people further north are sick of the snow, I'm sick of the rain. I'm careful saying it because it seems sacrilegious—not long ago we would have given anything for rain. There doesn't seem to be an in-between anymore, it's all one extreme or the other.

Maybe because of the long cool winter (or spring? not sure what season we're in!), the Grevillea 'Flora Mason' in the backyard has been flowering far longer than it usually does; this is month 4!

Tucson's Pima Prickly Park: amazing what dedicated volunteers can accomplish

Tucson has no shortage of destinations for plant lovers. I've blogged about many of them before, including my personal faves: the Arizona-Sonora Desert Museum, Tohono Chul Park, and the Tucson Botanical Gardens. Although they're different in their own ways, they have one thing in common: they're run by organizations with a professional staff.

Then there's Pima Prickly Park: a public desert garden that has neither a professional staff nor much of a budget (if any).


Located on West River Road next to the offices of Pima County's Natural Resources, Parks and Recreation Agency, the 7-acre property is owned by Pima County. What makes the site so special is that it was "adopted" by the Tucson Cactus and Succulent Society (TCSS) in 2010. Run by the TCSS under a 15-year operating agreement with Pima County, Pima Prickly Park was officially dedicated in September 2012. TCSS members have volunteered countless hours and donated countless plants to create a desert habitat park that highlights opuntias (prickly pears and chollas) and compatible desert plants. The park is not fenced so it's basically open anytime, although technically the hours are from sunrise to sunset. There is no fee for parking or admission.

I first visited Pima Prickly Park on New Year's Day 2015 when it was still very much a work in progress. My second visit was exactly four years later, New Year's Day 2019. I could hardly believe it was the same place. The 3000+ additional hours put in by TCSS volunteers between early 2015 and early 2019 have made an enormous difference. Anybody who has ever been involved in a club dependent on volunteer work can appreciate what a monumental achievement that level of participation is, even for a club as large and active as the TCSS.

Bach's Cactus Nursery in Tucson on a chilly winter day

Since I'm housebound because of the rain and can't do any work in the garden, let's go on a virtual nursery visit. The experience may be vicarious, but at least we'll stay dry.

Last New Year's Eve, I visited Bach's Cactus Nursery, one of Tucson's best retail destinations for succulent lovers. It was a cold day, the sky heavy with menacing-looking clouds, and I didn't expect the nursery to be busy. It wasn't, but I wasn't the only customer either, which surprised and pleased me.

Bach's is located north of downtown, not exactly out in the country but not in a bustling part of town either. The turnoff onto the dirt road/driveway that leads into the nursery does look decidedly rural:

Tohono Chul really is one of Tucson's best-kept secrets for desert plant lovers

Recently two different people asked me if I had ever been to Tohono Chul Park in Tucson and, if so, what I thought of it. The answer is easy: yes, and I love it.

I visited Tohono Chul for the first time in 2013, then in 2015, and again last December. If it were in a different town, Tohono Chul would be the leading botanical attraction. The fact that in Tucson it's relegated to a lesser tier speaks volumes about the quantity and quality of parks and gardens available there. Tucson not only has a national park (Saguaro National Park), a world-class zoo, natural history museum and botanical garden all rolled into one (Arizona-Sonora Desert Museum), another botanical garden (Tucson Botanical Gardens), a campus-wide arboretum (University of Arizona), and a score of smaller parks—not to mention great nurseries. Not bad at all for a city of 500,000!

I think Tohono Chul can easily hold its own, even in a crowded field like that, and deserves to be much better known among out-of-town visitors. I have a feeling, though, locals are quite happy to have Tohono Chul mostly to themselves and let the tourists flock to Saguaro National Park and the Desert Museum!

Tohono Chul Park is a 49-acre “living museum” that was once the home of a Tucson couple who fought hard to preserve a slice of native desert. Today Tohono Chul—“desert corner” in the language of the Tohono O'odham—combines nature with art and culture. Miles of trails wind through natural areas and demonstration gardens while three art galleries, classroom facilities and a fine-dining tea room offer attractions for people who are less plant-crazy.

A crisp Arizona morning at Boyce Thompson Arboretum

In the last couple of days, Arizona saw plenty of rain and snow. Flagstaff set a new snowfall record for Thursday, February 22. The Arizona-Sonora Desert Museum west of Tucson posted photos of snow-covered cactus, as did the Boyce Thompson Arboretum in Superior, east of Phoenix.

The weather was much less severe when I was at Boyce Thompson Arboretum (BTA) on December 30. It was  cold, as you can see below, but the sun was out and the air temperature had climbed into the high 40s by the time I left at noon: not as warm as during previous visits in December, but just fine for walking around. In fact, I was so into the plants and scenery all around me that I didn't have time to think of anything else.

You might say that I was in my element!

...which of these aloes is the prettiest of all?

Mirror mirror on the wall, which of these aloes is the prettiest of all?

"All of them," would be a good answer. Or, "that changes daily." Or, "depends on the mood I'm in."

My answer is even more diplomatic: I'll let you be the judge!

Below are most of the aloes in our garden that are in bloom, very close, or at the tail end.

Aloe marlothii, flowering for the first time ever. It looks like the flowers will be more yellow than red, which is what I was hoping for.

Rain is good—until it's too much

The biggest threat to our plants in the winter is usually the cold. This winter, the lowest nighttime temperature we've had was 30°F, as well as multiple nights right at 32°F. It's ironic, then, that something else has turned out to be the biggest problem—something we were begging Mother Nature for just a few years ago: rain.

In a region where the specter of drought is always a lurking presence, rain is a good thing. Until it isn't. In just the last few days, we've had flooding up and down California (Valentine's Day was the wettest day in Palm Springs in 76 years!), landslides, sinkholes, not to mention toppled trees and more minor incidents.

Nothing so dramatic happened in our little corner of the world. But considering we've had 12.5" of rain since December 1 (vs. 3.7" the year before),  I've become increasingly worried about rot from the excessive rainfall, especially after the 'Desert Love' incident. On Wednesday, I decided to grab what plastic sheeting I could find in the garage and drape it over some of the more vulnerable xeric plants in the front yard. I know it was more to make myself feel better than to effect any real rain protection for the plants, but sometimes that's all we can do.

Finding Nemo the rare Mount Diablo manzanita

I seem to have a thing for plants that start with A: Aloe, Agave, Acacia, and now Arctostaphylos aka manzanitas. With smooth or peeling bark ranging in color from cinnamon to chocolate, contorted branches, stiff leaves in hues from apple green to silver, and masses of small bell-shaped flowers in late winter frequently followed by tiny fruit resembling little apples (hence the Spanish name), their presence cannot be denied.

While some manzanita species are present in other western states as well—the prostrate kinnikinnick or bearberry (Arctostaphylos uva-ursi) is even found in the polar regions of North America, Asia and Europe—the biggest concentration is in the California Floristic Province (CFP) which stretches from southwestern Oregon into northern Baja California. According to the Field Guide to Manzanitas, 104 of 105 currently recognized Arctostaphylos taxa (species and subspecies) are native to the CFP. (The 105th, oddly enough, grows only at the top of several volcanic craters in Guatemala, thousands of miles from its closest manzanita neighbor.)

The county where I live, Yolo, is home to only one species (the common manzanita, Arctostaphylos manzanita subsp. manzanita), but some of the biggest manzanita hotspots are an easy drive away: Sonoma County (17 species and subspecies), the greater Bay Area (27), and Santa Cruz and Monterey Counties (27). It's one thing seeing plants you like in a residential or public garden, but it pales compared to the real deal: seeing them grow in their natural habitat.

Even though I've done some reading and have seen different manzanita species in botanical gardens, my practical skills at identifying them are virtually non-existent. Some species are very distinct, but many others (especially subspecies) are difficult to tell apart. The best clue is location: the native habitat of a manzanita is probably the best criterion in order to narrow down the possibilities.

Softly undulating hills dotted with oak trees are a typical landscape feature in our part of California

With that in mind, I decided my first manzanita outing of the year should be to a spot that only has two species: Black Diamond Mines Regional Preserve near the city of Antioch in the East Bay.

Desert Love in trouble

Philosophical question of the day: Is déjà vu a good thing? 

Yahoo has the answer: "For your own safety," one user writes, "'deja vu' should be understood for the same reason a venomous snake should be understood, or more mysteriously, an unidentified creature." 

 What now?

"Sometime it happens right before a seizure," somebody else says, "but that is very rare. So don't think you are going to have a seizure."

Whew, good to know!

"It is neither, or both, depending on your reaction," states a very smart person. "It is an experience that can awaken an awareness of what is going on in your life, and you need to just pay attention! There are things to be learned."

Time for a learning moment—maybe.

Agave ovatifolia 'Frosty Blue' in February 2018

Almost a year ago I lost an Agave ovatifolia 'Frosty Blue' and an Agave 'Snow Glow' to rot. I was never able to figure out definitively what happened. I removed the rotting carcasses and drenched the area with two kinds of fungicide. Then I planted an Aloe africana and an Agave 'Desert Love', a Plant Delights hybrid involving Agave ovatifolia, Agave parrasana and possibly Agave asperrima.

Let the light in: much-needed bamboo thinning taming

The three clumping bamboos in the front yard (all of them Bambusa species) are happy and healthy even on a much less generous watering regime than in the old days before the drought. That, in turn, makes me happy because I love the lushness they contribute to our garden.

For most of the year, I just let the 'boos do their thing. In the winter, however, when the sun is low in the sky, it becomes obvious how much the Asian lemon bamboo (Bambusa eutuldoides 'Viridi-vittata') shades the smaller succulent mound. Take a look at the photo below to see what I mean.

The Asian lemon bamboo is a fairly dense clump of culms and leaves:


It looks great, but it creates more shade than the other plants need or want.

New Hans Hansen ×Mangave releases for 2019

I was very excited to find two boxes at the front door last week, especially since I didn't know they were coming:


My mystery mangave benefactor was wondering if I'd like to trial the latest creations from Walters Gardens in Zeeland, Michigan where mangave wizard and plant genius at large Hans Hansen practices his hybridization magic. Except for one plant in the box, ×Mangave 'Mission to Mars', they were all new to me.

Opening boxes is a truly exciting thing. Maybe I should up my game and start producing unboxing videos like so many people on YouTube, but for now this is the best I can do:

Photo of the Day: shoutout to the humble jade plant

Photo of the Day for Friday, February 1, 2019:

Jade plant (Crassula ovata)

The jade plant (Crassula ovata) is so common here that it gets very little respect. It's even worse in the Bay Area where it grows so effortlessly that some consider it a weed.

I must admit that I'm not always good to our jade plant either. It's not an automatic drip, so in the summer it gets water whenever I think of it—which maybe as infrequently as once every six weeks.

And yet, it takes no offense and it holds no grudges. Instead, it flowers for weeks on end, bringing a smile to my face whenever I walk by.

Humble jade plant, I see you, and I will be more kind to you.

Photo of the Day: Acacia baileyana starting to bloom

Photo of the Day for Thursday, January 31, 2019 (yikes, the last day of January already!!!):

Acacia baileyana 'Purpurea'

Late winter is acacia time around here. Our Cootamundra wattle (Acacia baileyana 'Purpurea') is now 20 ft. tall and covered with blossoms. This is one of the first branches with open flowers. I love the contrast between the bluish-silver leaves and the golden-yellow puffball flowers.

This is the first time this acacia has flowered.

Agave hunter Ron Parker's personal collection

I recently reviewed Chasing Centuries: The Search for Ancient Agave Cultivars Across the Desert Southwest, Ron Parker's groundbreaking book about agave species cultivated and refined by the pre-Columbian cultures of Arizona. It's a book unlike any other, and I highly recommend it if you have even a passing interesting in the prehistoric peoples of Arizona and, of course, agaves.

On my after-Christmas Arizona trip, I had the opportunity to visit Ron on his home turf in Fountain Hills, northeast of Phoenix. To say that where he lives is pretty is like saying the Grand Canyon is alright. This is the view west from his street:


And this is his front yard:

This is the Environmental Horticulture building. You'd think that they'd use this planting bed as showcase for their department! Unless the weeds aren't weeds at all but a new kind of plant breeding breakthrough?

Debris-collecting Agave macroacantha had to go

Once upon a time, in March 2014 to be precise, I planted a beautiful Agave macroacantha outside the front yard fence, next to the 'Black Lace' elderberry and one of three Aloe 'Moonglow'.

When I say beautiful, this is what I mean:

Agave macroacantha with backlit marginal teeth and terminal spines

It looked like this right after planting:

Hechtia fosteriana (AS439)

Hechtia fosteriana is a terrestrial bromeliad native to Oaxaca, Mexico. Like many hechtias, it changes color throughout the year in response to cold, heat, and availability of water. My specimen came from Andy Siekkinen. I'm nuts about this color!

Photo of the Day: Acacia merinthophora

An ongoing project at work is taking up so much of my time that it's affecting the number of posts I'm able to write for Succulents and More. Right now, I seem to be managing no more than two a week. 

That's not enough for me.

To make up for it, I've decided to give myself a challenge that won't be a big time commitment: Starting right now, I'll post one new photo a day. It could be from our garden or from anywhere I happen to be that day. That'll allow me to share a small vignette of my life with you on a more regular basis.

Here's the Photo of the Day for Thursday, January 24, 2019:

Zig-zag wattle (Acacia merinthophora)

With their lack of real leaves, acacias are an odd bunch to begin with. The zig-zag wattle (Acacia merinthophora) is even odder since it's taking the no-leaf business to an extreme. The long greenish things you might think are leaf stalks (petioles) with the actual leaves missing, are called phyllodes. That's all there is—no conventional leaves at all. These phyllodes are actually modified (often flattened) petioles that carry out photosynthesis, i.e. they do what a leaf would do on a "normal" tree.

Our Acacia merinthophora has been blooming for weeks now. Even though the pom-pom flowers are small, they are very fragrant. It's a good thing I love the smell of acacias. To me, it means spring is right around the corner. True or not, I choose to go with what this zig-zag wattle is telling me.

Aloes getting ready to flower in our garden

We had a couple of nights a degree or two below freezing in December, but it's been warmer than usual since then. Not that I'm complaining; I'd happily never experience frost again, at least not where I live. If this weather keeps up, it won't be long now before the aloes in the front yard will be in full bloom.

This Aloe wickensii (lumped by some in with Aloe cryptopoda) has a head start on the others. It has never looked this good before:

Catching up with agave wizard Greg Starr in Tucson

Over the years, I've become friends with Greg Starr, author of the Timber Press book Agaves: Living Sculptures for Landscapes and Containers and owner of Starr Nursery. I visit him and his wife Carol whenever I'm in Tucson, and this time was no exception. I always love hearing about his discoveries on agave expeditions to Mexico and seeing what he has growing in his greenhouses. And I never fail to find cool plants I simply must have.

Greg lives on the west side of Tucson, pretty close to the edge of the city. The Tucson Mountains are just a few miles away; beyond them are the western unit of Saguaro National Park, the Arizona-Sonora Desert Museum, and the Old Tucson Studios theme park.

The properties in this part of Tucson seamlessly merge into the desert. "Borrowed scenery" is not just an abstract concept here, it's reality:

Electric Desert: after dark at the Desert Botanical Garden

The Desert Botanical Garden (DBG) in Phoenix, AZ likes to light up the night. When I was there in December 2013, they had a large-scale exhibit of Dale Chihuly glass sculptures which attracted crowds both during the day and at night (a record-breaking 631,000 visitors). In December 2015 they hosted Bruce Munro's Sonoran Light installation (318,000 visitors). This year, it was Electric Desert, created by video artist Ricardo Rivero and Klip Collective.

Electric Desert

On each of these occasions I went in December, which allowed me to experience both the special exhibit and Las Noches de las Luminarias, a beloved holiday tradition at the DBG combining 8,000 luminaria bags (hand-lit every night by volunteers) and holiday entertainment in nine different spots throughout the garden.

Off the grid in the Arizona desert: Jan Emming's Destination:Forever Ranch

A large parcel of land away from it all, surrounded by scenery so beautiful you want to cry, with no neighbors in sight and the freedom to do exactly what you want: Who hasn't dreamed of that at some point in their lives? I certainly have. But how many people actually turn this heady fantasy into reality? Precious few.

However, there are some who do. Jan Emming is one of them. A Colorado native, he began in the late 1990s to scour the western U.S. for a site where he could create the desert garden he'd been envisioning since he was a teen. In 1998 he found what he was looking for: 40 acres in northwestern Arizona near the small town of Yucca.

This is a very special spot where the Mojave meets the Sonoran Desert. I was astounded to find Joshua trees, the signature plant of the Mojave, growing side by side with saguaros, the signature plant of the Sonoran. Add ocotillos, chollas, hedgehog and barrel cactus, California junipers and scrub oak, and you have a great start for a desert garden. When I pulled into the driveway of Jan's property on the morning of December 28, I understood immediately why he had chosen to live there.

But let me back up a little. I got off Interstate 40 at the first exit for Yucca. If you've ever driven this stretch, you've probably seen this quirky structure from the road:

Golf Ball House aka Area 66 off I-40 in Yucca, AZ

Known as the Golf Ball House, it was built in the 1970s as the restaurant and night club for an ambitious real-estate project that went belly up before it ever got off the ground—a metaphor for so many desert dreams that go poof. Later owners built a store and renamed the property Area 66, but when I stopped to take some photos, the gates were locked and there was no sign of life.

My Arizona haul: spikes, rocks, and metal Mariachi musicians

I just got back from my after-Christmas road trip Arizona. I drove 2,223 miles in seven days, visited six public and three private gardens, took 1,800 photos, and returned with a car full of goodies. My rental plantmobile was a Chevrolet Equinox, an small SUV with plenty of room, and yet I managed to fill it with my purchases and finds: a wild assortment of plants, rocks, and other stuff that somehow ended up in the car.

In case you're wondering what my favorite trophy is:


Two totem pole cactus sections (Lophocereus schottii f. monstrosus) I found on Phoenix Craigslist for $10. Yes, ten bucks. Considering a rooted two-foot specimen can be $50 or more in a nursery, this is the steal of the year. These two will take up residence in the bed next to the front door when I redo it in the spring.

Happy New Year from Arizona

Happy New Year, everybody! May it be filled with lots of joy, laughter, and prickly plants.

Speaking of prickly plants, I've been seeing my fair share of them in the last five days. I'm on my annual after-Christmas road trip, and this time I'm back in Arizona. I'll have detailed posts about plants and places in the weeks to come: Desert Botanical Garden, Boyce Thompson Arboretum, Arizona-Sonora Desert Museum, and Tohono Chul, just to name a few.

In the meantime, here are a few random snaps to tide you over:
