Description

Adam's Needle Yucca (Yucca filamentosa) is a slow-growing broadleaf evergreen perennial. Blue-green leaves form rosettes about 2-3 feet tall and wide. Tall white flower spikes reliably appear on mature plants in May and June. If pollination is successful, attractive seed heads form later turning to black before cracking open. Although yuccas are more typical of western deserts and grasslands, this one is native to central and eastern United States. Tough as nails, yuccas are the ideal plant for a no-maintenance garden. Normally a plant has specific requirements for success but Adam's needle yucca has only one: it cannot tolerate growing in standing water or really wet soil. Plant in full sun to dry shade in any soil! In the landscape yuccas are often seen planted alone by a mailbox or neglected old landscape because they have outlived the original owners and the landscape service life. The root system of decades old plants may take up the underground volume of a large trash can. Yuccas look best when combined with other flowering plants providing texture and color. In mass plantings, yucca can create an interesting architectural look. Combined with ornamental grasses, yuccas can create stunning contrasts with winter grass colors of pink, orange and rust. Yucca flowers are pollinated exclusively by the yucca moth and deserve a place in native plant and pollinator gardens. This is a true 4-season "Once it's there, it's there forever" plant! 'Excalibur' is a beautiful compact bluish variety with lots of attractive curly white filaments on the edge of the leaves.
