Some native plants can be mixed in with other plants requiring summer water, but most can not. This is called the garden tolerance of the native plant. Most native plants have poor garden tolerance, which just means they will not thrive if exposed to normal garden conditions like rich soil, fertilization, and summer irrigation. They may even die.
Read MoreFrom now through July the beautiful and vigorous native plants in our native garden will bloom in turn. This is their active season, with water in the soil from winter rains, and warm days ahead. By July, the soils are dry and the fogs roll in. Our native garden quiets down, because the dry late summer months are the dormant time for California native plants.
Read MoreWhat makes a garden beautiful in winter? Although our mild climates let some blossoms from late summer and fall hang on plants into January, it is not flowers that make a beautiful garden in the dead of winter. In winter, the shape and structure of the garden is unclothed. Here are some factors to consider as you look out your window at the wet or chilly garden this month.
Read MoreSadly, part of winter work this year at the GFE includes removing our beautiful Mexican feather grass (Stipa tenuissima or Nassella tenuissima). This lovely, mobile, golden grass has been a signature plant in our border, framing our gates and stairways. But we have learned that this grass, while well-behaved in our garden, has become weedy and invasive in neighboring wild lands.
Read MoreDeer grass, coyote bush, hummingbird sage, sandhill sage, sea thrift, even the names of our native plants sound like a poem. They conjure up a time not so long ago when the San Franciscan peninsula was a mix of dunes, low hills and valleys, where seasonal creeks threaded between shrubby, windswept slopes until they fed into the few year-round creeks running to the bay.
Read MoreAs water policies and practices come under more and more pressure from increased demand and shrinking resources, we need one hundred words for drought tolerance. Part of the task of the Garden for the Environment is to refine what this word can mean, and experiment with real world plants, soil, weather, and exposure to find out which plants can thrive with little or no reliance on summer irrigation.
Read MoreMany people, when they think about native plants, conjure up a vision of rangy, sparse, weedy looking shrubs. And sadly, many native plants have been set out around town in well-meant projects and then neglected, giving native gardening a bad name. But native plants, when well-cared for, can produce as many graceful, magical effects as plants from anywhere else on the planet.
