Symphoricarpos albus var. laevigatus ‘San Bruno Mountain’
This attractive low-growing form of our native snowberry is a Cal Flora Nursery selection from San Bruno Mountain. Its dimensions are about 8 inches tall and spreading. Indeed the spreading nature of this plant is robust and it should be included in areas where that is an asset rather than a liability. The wiry arching branches hold light green rounded leaves and the effect of the new growth is delicate and appealing. Tiny pink urn-shaped flowers decorate the branch tips, followed by small white fruits. Perfect for a lightly shaded bank or the light shade of a tree where it will be very drought tolerant. With total drought it may go summer deciduous but occasional summer water will keep it looking fresh. The flowers attract bees and hummingbirds.
