Cultivars/Varieties
'Green Carpet' - Becoming more common in the trade, this selection bears waxy deep green leaves on compact stems that do not trail like the species. It grows neatly and uniformly.
'Green Sheen' - Selected by Dale Chapman in Connecticut, this universally praised plant has leaves so lustrous as to appear polished. They are deep green and look good in sun or shade. The plant appears to be more tolerant of hot conditions than the species, but it is also more slow growing.
'Variegata' (also known as 'Silver Edge') - This form bears clean white marginal mottling on the glossy leaves. It is much slower growing than the species, but handsome when established.
