Real Californians Have Drought-Resistant Lawns
So says one local landscaper, who sees each backyard as a gateway to understanding — and thereby saving — the rest of the world.
"People complain that we don't have seasons here," says Michael Thilgen of Four Dimensions Landscape Company. "I understand what they mean. We don't have the classic, dramatic cycle. Ours is more subtle, but you can sense the season by your senses if you stay in touch with the natural world."
The traditional green lawn behind a white picket fence is a beloved symbol of well-being. Transplants from the East Coast have a lingering desire for that perfect patch of soft, fragrant, foot-friendly turf. That made sense early in the 20th century, when the ability to dam, pipe and spray water was new and seemed limitless.
These days, water is more scarce. That patch of green now represents something else: waste, carelessness and environmental damage. "I think it's a tossup, actually, between a traditional grass lawn and an artificial-turf lawn," says Thilgen. "The artificial turf is made of petrochemicals in a factory. But the living green grass requires water, which diverts it from the Bay. The two-stroke mower causes air pollution. The fertilizer soaks into the groundwater and into the nearest creek, causing algae problems. So which impacts the environment less?"

The answer, of course, is that neither is great. Instead, Thilgen and his cohort in the Bay-Friendly Gardening Coalition are gunning for your grass: The Lawn Reform Movement is here, and they want to reboot our perception of a healthy lawn.
Northern California has two main seasons: the wet season, from late October through March, and the dry season (spring and summer). "A lot of the native grasses have adapted to our Mediterranean climate," Thilgen says, "which means they go dormant in July and August, just when we're all hosting summer barbecues. It's kind of a shock, because people are emotionally attached to their lawns, and as Americans we're used to having it all. But the chickens are really coming home to roost, environmentally." We have to change our ways.
But it's not like taking medicine: Drought-resistant native-plant lawns can be beautiful, green and resilient –
just maybe not all at once, or not all in the same spot. Depending on what you
use your lawn for most, you can have "a smaller spot of grass and more of other
elements" chosen for green, for beauty and for heavy traffic — with the
result that, as you see up close how these native plants develop over time,
you'll begin to sense and recognize the subtlety of the NorCal seasons.
If You Want: Groundcover
- Creeping Thyme: "It doesn't have to be watered as often. It looks a lot like a lawn until it flowers, and then it's spectacular. But you don't want to play soccer on it, because you might step on a bee."
- Sand Strawberry: "We plant a lot in our gardens in between other plants. They grow over the wood-chip mulch to turn a brown place into a green place. They don't fruit very much — you get a big show of white flowers in the spring, and a smaller fruit than market strawberries."
- Yerba Buena: "This prostrate, spreading mint grows naturally in oak woodland and creates a green carpet. But you can't walk on it very much or you'll crush it."
If You Want: Local Grasses
- Carex Pansa: "It's not bone-dry tolerant, but requires much less watering than traditional grass. It grows about two feet tall, then collapses onto itself and creates sweeping wave patterns, like an ocean flowing and sweeping up and across. And then once in a while you cut it back with a weed whacker, and it sprouts again."
- California Fescue and Red Fescue: "A beautiful oak woodland grass that gets to be 12-18 inches with flowers twice that height."
- Red Fescue: "You sow this out by seed, it grows about 12' tall and then collapses like the carex. It's used by CalTrans for land management projects."
- Purple Needle Grass: "This is our state grass, and it's a lovely bunch grass with a slender, fine texture that used to grow in valley grassland all across the middle of the state."
If You Want: Durability
- Wood-Chip Mulch: "This abundant waste product from tree trimmers is a great material. It conserves water, rots down to provide nutrients to the soil, and makes a great woodsy and rustic path or patio."
- Native Sod: "There are a couple of companies now making sod with native grass that responds to mowing. It does go dormant in drought, so you've got to be ready for that."
- Steppingstones: Folks around here make their own, adding marbles, shells and other doodads to make them cute as can be. Create a path with them and you'll be less tempted to trample the carex pansa.
If You Want: Beauty
There are simply too many options to name. A visit to your local plant nursery or to Annie's Annuals will provide you with an array. Thilgen specializes in creating backyards "filled with different species that jostle with each other and delight the eye. You can put annual wildflowers in a caryx meadow so they blossom throughout the year."
Sounds dreamy. And it sounds like a trend that fires the
imagination and the senses.
