Some kinds, such as Yucca gloriosa, the Adam’s needle, and Y. recurvifolia, gradually form a stout trunk several feet high, but the hardiest and most easily grown kinds, Y. filamentosa and Y. flaccida sit more closely to the soil and only produce short basal . All flower in late summer or autumn. There are also varieties of Y. gloriosa and Y. filamentosa with yellow-striped leaves. All grow best in full sun and well-drained soil. No is desirable.
