HETEROTHECA
(Chrysopsis) villosa ‘San Bruno Mountain’.
Heterotheca villosa is a low perennial of the aster family, scattered
over much of the West. This cultivar hails from its namesake mountain south
of San Francisco. It makes a dense mat of trailing stems, each lined by fuzzy
narrow, dark green leaves. It begins to flower in late spring and can continue,
if irrigated and sheared once in a while, until fall, with many 3/4" golden
yellow “daisies” nestling over the foliage. Unlike its annual cousin,
the telegraph weed, this has been a well-behaved plant in the garden. Sun or
light shade, most soils, moderate to occasional watering. Probably hardy to
10oF. or less.
