California drought

110220_dead_palms2013 will enter the history books as the driest calendar year ever in California. The numbers are astounding—and sobering: Since January, Los Angeles has received only 3.6” of rain (average: 14.91”), San Jose 3.8” (average: 14”), San Francisco 5.59” (average: 21.45”).

Normally December is one of our wettest months; this year it’s been one of the driest on record. The snowfall in the northern Sierra Nevada, where most of our water supply comes from, has only been 10% of normal. A persistent high-pressure ridge stretching over a large swatch of the northern Pacific Ocean has been diverting the usual winter storms away from California. Meteorologists see no change for January, which means that precipitation will continue to be far below normal. And even when we finally see some rain it won’t make much of a dent in the water levels of our reservoirs because the soil will suck up most of the moisture, resulting in very little runoff. We need a series of very wet storms to bring us back to a semblance of normalcy.

The odds of this happening are not good so gardeners need to be prepared to conserve water, either because of mandatory water rationing or simply because it’s the right thing to do. With a garden full of drought-tolerant shrubs and perennials, not to mention succulents, I feel I’m fairly well positioned. However, there is one major weak spot in our garden: the bamboos. While the bamboos in the ground should be OK with a little less water than what they’ve been used to (I already cut back in 2013, both in terms of watering and fertilizing), the potted bamboos will be pushed to the brink. As it is, the dozen potted bamboos that are left—from a peak of maybe 20 a few years ago—haven’t looked all that great since I reduced the amount of watering. Instead of the lush green screen I had envisioned, I see brown leaves and even dying culms. An even more draconian watering regime will mean the demise of many of them. Maybe that’s inevitable, considering that our climate barely supports potted bamboos. I’ll need to come up with alternatives to plant in all those containers. More potted agaves?

 

The precipitation numbers for Davis are as follows:
Average annual precipitation: 19.6”
Total precipitation for 2013: 5.22”
Percent of normal: 26.6%

Tucson Botanical Gardens (Tucson, AZ)

Yesterday afternoon (December 29, 2013) our backyard thermometer read 65°F. I was working outside in my t-shirt and I was hot! Crazy, but in a good way. After being sick for 10 days and then gone over Christmas, I finally removed all the frost blankets we had installed for the artic blast in early December. The damage looks to be fairly minor, with only a few losses, but I’m not ready to write about my own garden quite yet. Instead I want to stay in Arizona a little while longer, at least in my mind.

Today’s post is the last one from Tucson. While as a city Tucson is far from perfect—too much sprawl for one thing—it holds a special place in my heart. If I were looking to relocate, it would be near the top of my list.

The last place I visited while I was in Tucson in early December was the Tucson Botanical Gardens (TBG). Like so many public gardens, it started out as a private property. The structure you see in the photo below was the home of the Porter family, built in 1929. Many of the trees and shrubs surrounding the house are typical of what was in vogue in Tucson during the 1930s, 40s and 50s: olives, myrtles, pomegranates and citrus.

Agaves at the Arizona-Sonora Desert Museum, 2013 edition

The Arizona-Sonora Desert Museum (ASDM) exhibits and interprets the rich flora and fauna of the Sonoran Desert. Because it receives rain both in the summer and the winter, it is considered to be the “lushest desert on earth”[1]. The range of plants growing in the Sonoran Desert is astounding, including iconic cacti like the saguaro, but invariably I’m most drawn to agaves.

131203_ASDM_051

Arizona is home to 12 of the 18 agave species native to the U.S. (be sure to read this very interesting article about domestic agaves). The ASDM has them all, plus most species native to the two thirds of the Sonoran Desert that is in Mexico. The ASDM Plant Names Database lists 53 entries for agaves (38 unique species and 15 varieties and hybrids). My post has photos for 27 of them. Chances are I missed the others because they weren’t labeled and/or located in parts of the garden I didn’t explore this time.

Not every agave variety is a stunner. Some are downright weedy-looking, like Agave felgeri or Agave schottii. But many others, like Agave colorata, Agave gigantensis and Agave parryi, are truly beautiful. I’m sure you’ll find your own favorites—old and maybe even new ones.

The photos in this post are in alphabetical order so you can easily skip to a particular species that might interest you.

Merry Christmas!

Merry Christmas to you and your loved ones. I hope you’re enjoying a wonderful time surrounded by family and friends. And may Old Man Winter be kind to you until spring arrives. No more of that arctic blast, please!

Welcome to Succulents and More!

131203_ASDM_014As you may have noticed, Bamboo, Succulents and More is now Succulents and More. When I started this blog in October of 2010, my main interest was bamboo. However, over the years my focus has shifted to succulents. I’m still a bamboo aficionado and I will continue to write about bamboo, but this will now fall under the “More” umbrella.

Together with the name change, I’ve switched my blog to a new URL, www.succulentsandmore.com. If you have bookmarked the previous URL, www.bambooandmore.info, don’t worry; it will redirect automatically to the new web address. And if you access my blog through Facebook or Networked Blogs, nothing will change for you.

Arizona-Sonora Desert Museum (Tucson, AZ)

The Arizona-Sonora Desert Museum (ASDM) has a special place in my heart. This was my fifth visit, and any fear that I might be bored—especially since I’d just been there the summer before—were quickly allayed.

Founded in 1952, the ASDM encompasses 21 acres of Sonoran Desert west of Tucson. According to their website, there are “two miles of walking paths, 16 individual gardens, 1,200 native plant species and 56,000 individual plants.” If I had to venture a guess, I’d say most visitors, especially families, come for the animals. Others, like me, come for the plants.

Last year, I wrote three detailed posts about the ASDM (see links at the bottom). Please check them out to see the full range of botanical sights that await visitors.

The current post covers some of the same territory but I’m mainly focusing on sights I hadn’t shown you before. This post looks at agaves at the ASDM.

Right at the entrance are beautiful specimens of ‘Desert Museum’ palo verde (Parkinsonia ‘Desert Museum’). This is the hybrid I planted at our house this fall.

Tohono Chul Park (Tucson, AZ)

I brought home something very unexpected and undesirable from my recent Arizona trip: a nasty bug that sidelined me for almost a week—I literally didn’t set foot outside the house for six days—and gave me pinkeye (conjunctivitis) to boot. The last time I had pinkeye was in elementary school! Even now I’m dragging, and I have a hard time making it through the day without wanting to take a long nap. Fortunately Christmas and the promise of a week of relaxation is just around the corner.

In today’s post I’ll take you back to Tucson. We’ll visit Tohono Chul Park, 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.

For me, the main draw were the natural areas and the gardens so that’s what I focused on. Join me as I walk through Tohono Park on a Monday morning. The place was all but deserted (no pun intended) and it felt like it was all mine.

A visit with agave expert Greg Starr (Tucson, AZ)

If you’ve followed this blog for any length of time, you know that I love agaves. As you can see here, I have 50+ species and varieties in my collection, most of them in pots.

Before my Arizona trip, I contacted Greg Starr, author of the Timber Press book Agaves: Living Sculptures for Landscapes and Containers and one of the country’s leading experts on agaves, and he graciously agreed to let me visit him at his home in Tucson. As expected, it ended up being a personal highlight of my trip.

You can read more about Greg in his book and on his website, but here’s a quick summary: Greg’s nursery has been in business since 1985 and he has been botanizing in Mexico for at least as long. Since 1990 his main focus has been on agaves, and he has visited many type localities in Mexico. In recent years he has been working on a book on the agaves of Baja California. He is also working on a second edition of his first book, Cool Plants for Hot Gardens (now out of print).

Greg lives west of town at the base of the Tucson Mountains. The scenery is straight out of an old western movie. Here are some photos I took on my way to Greg’s house:

My Arizona plants have arrived

My plant purchases from my Arizona trip arrived today. The box I’d shipped from Scottsdale last Friday arrived more or less intact, but it didn’t seem quite as full.

131211_plants_from_trip_002

This is what the inside looked like:

I was very surprised since I’d filled the entire box with packing peanuts. Now it looked like a 3-inch layer was missing. Could the peanuts have settled that much?

Bach’s Cactus Nursery (Tucson, AZ)

Instead of dealing with the aftermath of the cold snap that has gripped us since Thursday of last week, I decided to write the first extended post from my trip to Arizona last week.

The first destination we’re going to revisit is Bach’s Cactus Nursery in Tucson. From a post Loree “Danger Garden” Bohl had written in December 2011 I already had an idea of what to expect. But I wasn’t prepared for the size of the nursery. It’s large! In fact, the friendly employee who gave me a ride on one of their electric carts told me that at 10 acres it’s the third largest cactus nursery in the country. (I don’t know what the largest two are.)

Let’s start at the entrance and work our way through the nursery.

Arizona day 6—Phoenix: Cosanti, Desert Botanical Garden

This morning I visited Cosanti, the 5-acre studio complex and residence of visionary architect and artist Paolo Soleri located in what is now a fancy residential area of Scottsdale. As you may remember from yesterday’s post, Soleri is the man behind Arcosanti, the experimental desert community near Prescott.

Soleri bought the land that would become Cosanti in 1955 and soon thereafter began to build the first earth-cast concrete structures. Soleri’s architectural philosophy was one of frugality: using the cheapest materials and simplest methods possible. Many of the structures began as shaped mounds of earth upon which a thin (typically 3-inch) layer of concrete was poured. When the concrete was fully hardened, the soil underneath the concrete “roof” was dug away, resulting in a structure that is partially or wholly underground.

Arizona day 5—Taliesin West, Arcosanti, Old West Cactus Farm

Two of today's three stops didn't have anything to do with plants. Instead, they were focused on another interest of mine, architecture.

The first stop has been on my bucket list for a long time, and I'm glad I can finally scratch it off now: Frank Lloyd Wright’s Taliesin West in Scottsdale. Built as his winter home and architectural campus on 600 acres he bought in 1937 for $6,500 (!), Taliesin West is a masterpiece of organic architecture, its deceptively simple lines and low-slung shapes mirroring the Sonoran Desert which surrounds it on all sides. Today it serves as the headquarters of the Frank Lloyd Wright Foundation and the winter campus of the Frank Lloyd Wright School of Architecture.

I did two tours, one of the most important buildings and a second of the desert that forms the majestic backdrop. Here are a few photos I took. I don't want to bore you to tears with pictures of architectural details, but I thought you might want to get a general impression of what Taliesin West is all about. If want to find out more, there is a wealth of information online.

Arizona day 4—Superior: Boyce Thompson Arboretum, Phoenix: Desert Botanical Garden Luminarias

This morning I left Tucson (sad face) and headed north towards the Phoenix area on Highway 79, the Pinal Pioneer Parkway. I was astonished by how much sprawl there is north of Tucson, but eventually I found myself in open country:

For a long while the scenery was dominated by creosote, cholla and saguaro:

Near the town of Florence (dominated by a large state prison), I came across this vignette: somebody’s desert dream gone bust.

Arizona day 3—Tucson: Arizona-Sonora Desert Museum, Desert Survivors Nursery, Tucson Botanical Garden

My first stop of the day was the Arizona-Sonora Desert Museum (ASDM). Located in the desert to the west of Tucson, this 98-acre park is one of my favorite places in Arizona. After visiting the Desert Botanical Garden in Phoenix a couple of days ago, I was afraid the ASDM might have lost some of its luster in my pantheon of favorite public gardens. Fortunately, that was not the case. The Desert Botanical Garden may have a larger variety of plants, but it also feels more “domesticated.” The ASDM, in contrast, is a bit wilder, especially the lower trails that are mostly natural desert. I love both, and I’ll never be able to pick a favorite among the two.

Here are some of the photos I took today:

Arizona day 2—Tucson: Tohono Chul Park, Bach’s Cactus Nursery, Greg Starr, Tucson Mountain Park, Saguaro National Park

Day 2 of my Arizona trip started at 8:00am with a visit to Tohono Chul Park, a 49-acre nature preserve in a northern suburb of Tucson. Aside from two bird watchers, I was the only visitor, at least at the beginning.

Tohono Chul isn’t a botanical garden per se, but there was plenty to keep me busy for a couple of hours. I’ll have a separate post in a week or two so I’ll limit myself to a few teaser photos.

Arizona day 1—Phoenix: Desert Botanical Garden

After arriving in Phoenix at noon, I spent the afternoon at the Desert Botanical Garden. This is the one of the premier public gardens in the country for xeric plants, and it has been on my bucket list for a long time. My expectations were sky high. Did reality live up to them? You bet! I’m still overwhelmed by everything I saw in the 3.5 hours I was there. Since I didn’t get a chance to visit every part of the garden, I’m going to rearrange my schedule so I can go back on Friday morning.

I will have several in-depth posts about the Desert Botanical Garden in the weeks to come, but here is a short teaser. The art displayed throughout the garden is by world-famous glass artist Dale Chihuly.
