What’s blooming

After a weekend that went by much too quickly and a busy Monday at work, I enjoyed a quiet stroll through the garden with my camera and macro lens. So many plants are in bloom now, and I love looking at flowers up close. The palette of shapes and hues really is endless.

I hope these photos will brighten your day like they did mine. As they say, a picture is worth a thousand words.

so I can keep the cycle going.

Calla lily (Zantedeschia aethiopica).
Many people think calla lilies are a cliché, but for me they are the epitome of floral elegance.
Love-in-a-mist (Nigella damascena). Quite a name. I wonder what the story is behind it.

The seeds came on the wind from across the street—last year it was one plant,
this year it’s a few dozen. Invasive, yes, but who can resist this beauty?

What’s blooming in your yard? What are your favorites?

The restios have arrived

Last week I fessed up to killing a potted Golden Goddess bamboo due to neglect. Instead of replacing it with another bamboo that would just end up being pot-bound in a few years, I decided to go with a restio. To summarize an earlier post, restios are rush-like plants native to South Africa and Western Australia, areas sharing a similar Mediterranean climate. Superficially resembling reeds or even bamboos, they are related to neither. Instead form their own family, the Restionaceae, or “restios” for short.

In our part of the world, restios are definitely a specialty plant. You can’t just walk into a nursery and expect to find a selection of them. If you’re lucky, you’ll find Cape rush (Chondropetalum tectorum), which seems to be the most common restio in California, but that’s about it.

I wanted some very specific restios, so I had to go the mail-order route. Luckily, one of the very few nurseries in the U.S. that has a decent selections of restios is located in Fort Bragg on the Northern California coast so I could order plants that wouldn’t have to be shipped half way across the country.

I was very excited when my order from Hortus Botanicus showed up less than a week after I had placed it.

The four plants I had ordered were packaged very well. The two in the middle, Rhodocoma capensis, had to be trimmed to fit in the box.

Four restios (left to right):

Rhodocoma capensis was what I had picked to replace the defunct Golden Goddess bamboo because it appears to be more drought-resistant than other restios—a plus for any containerized plant. The 1-gallon plant was extremely root-bound so I cut off the very bottom of the root ball and made some cuts all the way around. However, since I’m not really familiar with restios, I didn’t want to be too aggressive. I do know that restios, once planted, don’t like to have their root system disturbed so I hope what I did didn’t hurt the plant too much.

Planting the Rhodocoma capensis in the green pot next to the front door didn’t take long at all. Right now, it looks a bit lost in this large pot, but I’m hoping it will soon resume its vigorous growth.

The second restio I ordered, Elegia capensis, is considered one of the most beautiful members of this plant family. Read this article on the University of British Columbia web site for more information and a few photos.

Elegia capensis culms and branches

Elegia capensis has the potential to become a relatively large plant, 6-8 feet in height, given enough moisture. I planted it in front of our house outside the fence where it will benefit from the run-off from the lawn and inside planting strip. I’m concerned that there might not be enough space there, but it’s hard to know how well it will do in our area so I’m willing to take a chance. If it ends up being an 8 ft. specimen plant, I will gladly remove some of the neighboring plants to make more room.

I transplanted the other two restios, Rhodocoma gigantea and another Rhodocoma capensis, into 2-gallon containers for now while I’m trying to determine where they will go. If the Rhodocoma capensis in the green pot does well, I may remove the 2nd Golden Goddess bamboo in the front of the house (planted in an identical green urn) and replace it with the extra Rhodocoma capensis. When the time comes, I’ll know what feels right, and I’ll have the plant I need on hand.

If you’ve followed my blog for a while, you may remember that I planted another restio, Thamnochortus insignis, outside the front yard fence. While it hasn’t exactly exploded, it looks happy and healthy.

Just the other day I noticed that our neighbor across the street has a restio as well. It’s a Cape rush (Chondropetalum tectorum), the most common restio around here—although “common” makes it sound a lot more ubiquitous than it really is. It resembles California rush (Juncus patens), which is very popular with landscape designers at the moment.

I have not been able to find much information about growing restios in Northern California. Everything I’m doing is based on where and how these plants grow in their native climate, but I know that there’s a lot of trial and error ahead. However, I’m so taken with the unique beauty of restios that I’m willing to do what it takes to make them thrive in our garden.

Fellow blogger DD recently planted some restios in his San Mateo, CA garden. Check out his blog at modernistgardening.info.

5/30/11 UPDATE:

I put the other two restios (the second Rhodocoma capensis and Rhodocoma gigantea) in pots in the front yard.

Here is the second Rhodocoma capensis:

More cacti in bloom

Many of my posts this week were fairly depressing, dealing with hail damage, me inadvertently killing a potted bamboo, and such. Today I want to change the focus to something more uplifting to get you and myself in a positive frame of mind for the weekend.

A couple of weeks ago I posted a few photos of my Red-Headed Irishman cactus (Mammillaria spinosissima) beginning to flower. In typically mammillaria fashion, the tiny flowers form a ring that goes all the way around the cactus. This ring is now complete and looks fantastic.

Two other small mammillarias are blooming. The first one goes by the impossibly complicated name Mammillaria camptotricha cv. Marnier-Lapostollei. It has very odd-looking spines which aren’t even that prickly—more like bristles on a brush. It’s only a couple of inches wide and tall but it already has a couple of offsets along the side. The flowers are tiny but otherwise look like mammillaria flowers.

The next one is Mammillaria elongata 'Julio', currently about 3” tall and looking like a pickle with star-shaped bristles. Even this juvenile cactus is flowering freely, with tiny pinkish blossoms. As with the other mammillarias described above, the flowers are arranged in a ring around the upper ⅓ of the cactus. You can see a couple of small babies at the base.

The last cactus I want to show you isn’t even a cactus, technically speaking, but rather a euphorbia. In other words, it’s in the same genus as the woody spurges and—yes!—the ever-popular poinsettia. Euphorbia horrida looks very similar to star cacti (genus Astrophytum) of which I bought two at the Living Desert in Palm Desert, CA earlier this spring. Click here to see photos of these superficially similar cacti.

While astrophytums have large and colorful flowers, Euphorbia horrida has tiny and unassuming flowers. Still, in the grand scheme of things, it must be enough to keep the species going.

I’m pretty excited that so many of the small cacti in my collection are blooming already. That’s the kind of pleasant surprise that makes gardening so enjoyable!

Hail damage update

Last Sunday, we had a brief but intense hail storm unlike anything I had ever seen in the 14 years we’ve lived in Davis. Check out this post for details. 

Initially it looked like the damage would be fairly minor, but as you can see in the photos below, quite a few of our soft-leafed succulents (especially agaves and aeoniums) are dinged up. Luckily, the weather is warm and dry now so I don’t expect any rot to result from this as might have been the case in the winter. In addition, I’m telling myself that these are garden plants, not exhibition specimens, but I can’t help being a bit frustrated by the blemishes. If only I’d been with it and thrown blankets over the more sensitive plants. On the other hand, the hail came and went so quickly—and I was so busy taking photos of it—that I probably wouldn’t have been able to get to all of them anyway.

…but up close you can see the dings caused by the hail stones, like on this Agave lophanta ‘Quadricolor’

Even the very narrow leaves on this Agave dasylirioides sustained damage
This is one of my very favorite succulents, Mangave ‘Bloodspot’. The damage is a bit harder to see because of its speckled leaves, but it’s there.

In addition to these and some other agaves, our dark-colored aeoniums show very visible damage. Their leaves are soft and sensitive anyway; the epidermis must be very thin indeed.

Aeonium 'Zwartkop' looks pretty dinged up
Aeonium ‘Voodoo', similar to ‘Zwartkop’
but with more green in the center and leaves that are less “black”
Even this gray-green Aeonium haworthii shows hail damage,
and its leaves are noticeably thicker than ‘Zwartkop’ and ‘Voodoo’

Interestingly, the plants that got hit the hardest are the nasturtiums in our backyard. I had just commented on them the other day. Their leaves are super thin, and it looks like the hail stones went right through.

And yet, the largest-leafed plant in our garden, Farfugium japonicum ‘Giganteum,’ escaped unharmed. Its leaves are fairly thick and rubbery, and the hail stones must have simply bounced off.

As ugly as it is, the damage to the succulents is purely cosmetic. However, since agaves and brethren aren’t exactly the fastest growers this isn’t something that will disappear over night.

I’ve learned my lesson and will be better prepared the next time—although it could be a year or two or even longer before we have hail again. Aside from occasional high winds, our area isn’t prone to extreme weather. In fact, even thunderstorms are so infrequent that I get a thrill out of them when they do occur.

Bamboo surprise

In the spring of 2010, another bamboo aficionado sent me a length of rhizome (no culms) from Phyllostachys viridis, the all-green version of the popular Robert Young bamboo. The rhizome was a good foot long and looked fresh and viable, but I wasn’t sure whether it would survive. I buried it in a 22-inch galvanized steel tub and half forgot about it. Much to my surprise, new shoots came up within a month and turned into regular culms with an abundance of leaves, including a 7 ft. whip shoot that more or less grows horizontally (on the left in the first photo below).

Since Phyllostachys viridis is hardy to -5°F, it comes as no surprise that it wasn’t fazed by our mild winter. What did surprise me is how drought-tolerant this running bamboo is. While I did water it when I thought of it, that certainly didn’t happen with any kind of regularity. Considering that the soil depth in the tub is around 9 inches, I’m amazed that the plant remained lush and green throughout the summer, fall and winter. You can’t ask much more of a bamboo.

Hold on—yes, you can. You also want big culms. And it looks like this champ that came from such humble beginnings is going to deliver in that respect as well.

Take a look at what’s coming out of the ground!

Massive shoots

It’s hard to get a sense of scale from these photos, but the biggest two shoots are very close to an inch in diameter.

This shoot is 1” in diameter at the base
Another 1” shoot

For comparison, that is double the diameter of the culms produced this spring by our black bamboo (Phyllostachys nigra).

I have no idea how tall these culms will get considering that the plant’s rhizome and root system is severely constrained by the tub, but I could be in for yet another surprise.

Since this bamboo has the potential to turn into a true giant (50 ft. with 3” culms), I’m thinking it will soon have to go to my in-laws where it will have room to run.
