Cultivars/Varieties

'Argentea' (also sometimes listed as 'Variegata') - The only commonly available cultivar, it is a rare form that is difficult to propagate and therefore fetches a high price. It is a smaller, shrubby plant (to 15' tall) with layered branches and leaves that are handsomely variegated with a white margin. Specialty nurseries are beginning to offer this selection in greater numbers.
