Snuggled into the border of the Garden for the Environment, by the corner of 7th and Lawton, a glowing mound of lemon-yellow, wooly foliage covered the ground for many years. The bad news is that licorice plant (Helichrysum petiolare) has been listed officially as an invasive exotic, and no matter how useful it may be in the garden, it is no longer an appropriate plant for environmentally savvy gardeners to grow.
Read MoreThe mixed weather of June is over, and July and August in San Francisco are the months of fog, fog, and more fog. For gardeners, this means that just as gardens are really kicking into high gear in other parts of the country, and producing a year’s worth of warm season crops like corn, tomatoes, and melons, along with giant dahlias and roses, many San Francisco gardens have a letdown.
Read MoreIt’s too much to expect us to give up our tulips and crocuses “cold turkey.” Yet, this annual planting spree followed by throwing out the bulbs can’t last in a world were sustainability is the new byword. That’s why we need a substitute: beautiful, graceful spring flowering bulbs which are suited to our climate so that they can naturalize, returning year after year.

Read MoreDecember brought the blessing of rain, and a few cold nights; just enough to let the plants know that it is wintertime. In our microclimate, the year is like the proverbial snake eating its tail. Fall’s colorful leaves still persist as the first spring blossoms make a tentative trial. In just a few short weeks, we’ll see our first plum blossoms, and then the year will unfurl again, as it has so many times before.
Read MoreThere can be a special beauty in the winter garden. Cleared of last year’s growth, well-pruned, mulched and weeded, the garden in winter can still surprise and delight the eye. When a garden looks wonderful in midwinter, gardeners everywhere nod and say “that garden has good bones.”
Read MoreFor gardeners, this is a time for action. The ideal planting time for trees, shrubs, and perennials is now, with 5-7 cool, rainy months ahead. Plants set out as the rainy season begins can establish deep root systems before the stress of the first hot dry days, usually in May.
