RUBUS. Widespread, mostly in the Northern Hemisphere. Best known for the raspberry, blackberry and other fearsomely prickly, rampant shrubs with delicious fruit, this genus also includes some non-threatening and ornamental shrubs and herbs. The following are as different from one another as they are from their more famous brethren. Culture and tolerances as described below.
calycinoides Emerald Carpet. This is a dense evergreen carpet with slender, hairy stems and nearly round, lobed 1-2" leaves. The leaves are dark green above, grey-furry beneath. Though the little white flowers are attractive at close range, they are not particularly impressive. It is simply a pleasant, durable, and adaptable ground cover which deserves better recognition. Sun or shade near the coast, part shade inland, most soils, moderate to occasional watering. Hardy to 10oF. or less. Introduced by the University of British Columbia.
