Weblog of a Central Austin Garden

I make a trek to Las Vegas every couple of years solely because three generations of my family settled there. I never would have thought that Las Vegas held any interest for gardeners even though lot has changed since I went to high school there. All the new developments have a buffer of desert landscaping between the street and the concrete block walls that define each neighborhood. The new parks are all planted with waterwise landscaping. There is a lot more public art including some wonderful giant tortoises underneath the tangle of freeway near downtown. Even the cell phone towers are disguised as palm trees. Some people hate this but I think it shows a sense of humor and it looks better than a plain cell phone tower.

“Las Vegas” means “the meadows”. Ancient peoples and westward trekking pioneers found water and forage in this formerly bountiful valley. By 1962 the springs had been pumped dry and the original heart of Las Vegas languished. It’s now bounded by Highway 95 and The Meadows shopping mall. In 2002, Las Vegans voted to create the 180 Springs Preserve, overseen by the Las Vegas Water District. Not only does the preserve contain historical and archaelogical sites, the future home of the Nevada state museum, and an interactive exhibit hall, it is a model of instruction on how to live and garden in a desert. Las Vegas survives on borrowed water. It is not just an ecological disaster waiting to happen, it already happened.

The gardens at the Springs Preserve are designed to teach water conservation through water-efficient landscaping–to show that xeriscaping does not have to be zero-scaping (as my Illinois-born dad calls it). The Springs Preserve shows us when we stop taking our way of life for granted, we can tap into our creative potential and discover better ways to live.

The cactus gardens were designed by someone with a master’s eye for form, texture, balance, and harmony. All the plants are carefully labeled, as they should be in a good botanical garden. (I hate discovering a plant I love at a garden without being able to find out its common and botanical names.)

The variety of plants was astounding. Over 1200 species were moved from the original Demonstration Gardens to the Springs Preserve Garden Walk before its opening in 2007. The plantings at the Springs Preserve made even some of the English estate gardens I’ve been to seem rather prim and dull. After looking at these incredible textures and forms, don’t beds of pansies or tulips seem a bit tame?

I’ve never been a big fan of cactus gardens but that apparently because I’ve never seen a really well-designed one before.

I’ve never been a fan of palm trees either. And yet I stood amazed at how artfully the palm trees had been arranged. Again, this is first a botanical garden, so the main purpose was to show the great variety of palm trees available. (Compare my favorite, the Canary Island Date Palm, on the left, with the others.) But the designers went a step further and created a beautiful planting.

I fell in love with this Canary Island Date Palm, Phoenix canariensis, because of the texture of its trunk and the unique bulge at the top. (Should I buy one?)

After writing about my own maintenance headaches with rain gardens, I was happy to see a lovely example of a rain garden gone right. Hints: create rain garden away from trees and install waveform sculpture. (Isn’t it clever without being too cute?)

Living for a time both in the American desert southwest and Japan, I’m quite attracted to the aesthetic of gravel gardens and dry creek beds. As there is no shortage of rocks of all sizes in my yard, I group like rocks together in various configurations. Because I live on a slope, I often arrange rocks to follow the topography, creating an informal dry stream.

This year rain gardens seem all the rage (4,080,080 hits on Google or check out Pam/Digging). And they always look so clean and tidy when first installed, while at the same time looking natural. However, in my experience, they don’t remain clean and tidy very long. My biggest problem is leaves. In Austin, leaves can start falling in September with the cedar elms (if it’s a typical summer–2007 was wet and the leaves held on until October) until February with the live oaks (which haven’t started dropping their leaves yet). In my yard I also had hackberry and chinaberry trees (which I cut down this year) and red oaks. So for five months, leaves are clogging my dry creek beds and I can never keep them clean. The cedar elm leaves are the worst because they are small and break down quickly. They mess up my gravel courtyard and my gravel walks, too.

Then there’s the weeds. Gravel is an excellent medium for sprouting seeds. It doesn’t matter if you put landscape fabric underneath the gravel (I did on my paths but not in my garden which is more free-form). The seeds fall on top of the gravel, work themselves down, and then sprout. I spent all afternoon digging that hated horseherb and spiderwort out of this small section of the meadow so that I could replant it with larkspur and California poppies.

So what’s the secret to maintaining gorgeous rain gardens? Do I have to move back to a treeless landscape? I guess I’ll start reading some of those 4,080,080 articles…but I’ll have to finish weeding first.
