Horticultural selection from Arctostaphylos uva-ursi. One of the faster growing manzanitas, Arctostaphylos uva-ursi 'Green supreme' is truly superior when it comes to dense, low, evergreen ground cover. 'Green supreme' has noticeably brighter green leaves than most manzanita, a brilliant contrast with the plant's ruddy branches and stems. With very little to no die back in the center, Green supreme's exceptionally dense foliage helps suppress weeds. This manzanita grows just 6 inches tall but can spread up to 12 feet. It does well on slopes, thriving in well-drained soil but also grows well in heavier clay soil that has reasonable drainage. 'Green supreme' enjoys full sun and is drought tolerant, but occasional watering every 4-6 weeks will keep this manzanita looking extra dapper. Green supreme is frost hardy to 15 to 20 °F. It is more reluctant to bloom than other manzanita varieties, but a scattering of white to pale pink flowers will appear in late spring to early summer. Green supreme is a garden hybrid introduced by the Tilden Botanic Garden. Tolerates almost any soil type. Prefers sun in coastal sites, and part shade in inland sites.
