The Great American Desert

[I wrote this piece a few years ago, but the History Channel's recent broadcast of Black Blizzard, along with Tim Egan's narrative and interviews with Dust Bowl survivors, makes it worth repeating.]


"When the native sod of the Great Plains was in place, it did not matter if people looked twice at a piece of ground. Wind blew twenty, thirty, forty miles an hour, as always. Droughts came and went. Prairie fires, many of them started deliberately by Indians or cowboys trying to scare nesters off, took a great gulp of grass in a few days. Hailstorms pounded the land. Blue northers froze it so hard it was like broken glass to walk on. Through all of the seasonal tempests, man was inconsequential. As long as the weave of grass was stitched to the land, the prairie would flourish in dry years and wet. The grass could look brown and dead, but beneath the surface, the roots held the soil in place; it was alive and dormant.
The short grass, buffalo and blue grama, had evolved as the perfect fit for the sandy loam of the arid zone. It could hold moisture a foot or more below ground level even during summer droughts, when hot winds robbed the surface of all water-bearing life. In turn, the grass nurtured pin-tailed grouse, prairie chickens, cranes, jackrabbits, snakes, and other creatures that got their water from foraging on the native turf. Through the driest years, the web of life held. When a farmer tore out the sod and then walked away, leaving the land naked, however, that barren patch posed a threat to neighbors. It could not revert to grass, because the roots were gone. It was empty, dead, and transient."

Legends of the Fall

One of the things I hear from clients who have moved to California from other regions of the country is, "there's no fall color here." And while I'll grant that the Bay Area is no New England, I have to say that this autumn the trees seem particuarly brilliant.

While lots of factors influence fall leaf color, what I've noticed this year is that [a] we had a fairly mild summer, so fewer leaves scorched and departed early; [b] the cold nights arrived with a vengeance right around the autumnal equinox, giving the trees not one but two cues (light and temperature) that it's time for dormancy; and [c] the dry summer has persisted into fall, stressing trees into withdrawing their green chlorophyll earlier and more quickly (thereby revealing the natural anthocyanins and carotene colors).

Some trees with legendary fall color include Acer freemanii (Red Maple), Ginkgo biloba (Maidenhair Tree), Quercus coccinea (Scarlet Oak), Acer griseum (Paperbark Maple), the native Acer circinatum (Vine Maple),
and of course the reliably fluorescent Pistacia chinensis (Chinese Pistache) and Liquidambar styraciflua (Sweet Gum). From a drive around my Palo Alto neighborood this morning, I've posted photos of these and more at my Flickr site.

To my eye, the colors peaked late last week, so as you're out and about over the next few days, I hope you'll make it a point to notice and appreciate the colors before they come back to earth. If you see something particularly stunning, feel free to send it in. And if you have favorite autumn plants of your own, please share!

Landscaping Small Spaces, Part 5

As much as I love the possibilities afforded by designing larger estate landscapes (as in, trees! I actually get to spec trees!), small gardens hold a special place in my heart as well. Here's the last of five bite-size tips to make the most of bite-size spaces:

Dry out. Because small yards are often planted right up to the house, using water-thrifty vegetation is one way to ensure foundations stay dry. Check with your local water utility for a list of recommended native or low-water plants for your area. Downspouts often may be tied into main lines that collect water in detention basins elsewhere on the property; from there, the water can percolate back to the groundwater. A French or trench drain along the home's foundation may also be useful for picking up extra water. And while these drain inlets often are topped with gravel, recycled colored glass may also be used, and even lit from beneath for a dazzling effect.

There are plety of other ways to add big impact to a small space. What are some of your faves?

Landscaping Small Spaces, Part 4

As much as I love the possibilities afforded by designing larger estate landscapes (as in, trees! I actually get to spec trees!), small gardens hold a special place in my heart as well. Here's the fourth of five bite-size tips to make the most of bite-size spaces:

Get wet. A modest fountain can create a big impact in a small space, especially with interesting lighting. Vertical columns of basalt rock can be drilled to create a naturalistic water feature, or employ a classic or modern container for a more elegant effect. A product such as the Aqua Box makes installation easier than ever. One or more translucent plastic tubes can be installed on end to create subtle waterfall effects, and metal salvage yards can also be a source of interesting fountain elements, from corrugated metal to stainless steel troughs that can spill into a basin below grade.

Landscaping Small Spaces, Part 3

As much as I love the possibilities afforded by designing larger estate landscapes (as in, trees! I actually get to spec trees!), small gardens hold a special place in my heart as well. Here's the third of five bite-size tips to make the most of bite-size spaces:

Think big. Small spaces get cluttered quickly, so resist the temptation to landscape on a petite scale. Instead, make a statement with a chunky, oversized pergola; boulders large enough to sit on; or a dramatic container that takes command of the space. Mirrors (or polished steel plates) can be used to reflect light and enlarge views; and large gates or doors, either freestanding or mounted on fences or walls, create the illusion of additional space beyond. Limit your planting palette to just a handful of species; it's far more effective to use a dozen each of three different plants, than three each of a dozen species. And if there's not enough space for all the full-size dining chairs you'd like, consider framing the dining area with a wood bench that will both define the room and provide additional seating when it's needed.

Next, I'll write about my fourth tip for landscaping small spaces: Get wet.
