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 selection introduced by the Tilden Botanic Garden.
