The Q&A Archives: yucca recurvifolia

Question: Purchased 3 yucca recurvifolia for use as border plants along chain link fence to block view of road. Your label says max. size is 6-8 feet high and wide. Will they get that big in zone 6, 5000 feet elevation? How long will it take to reach full size? Two desert willows are about 5 feet inside the same fence. Are they compatible with yucca? Will we be able to control the size of the yucca so they do not invade the fence? We would like to plant them about 4 feet inside the fence and 7-8 feet apart. We selected them for size, low water use, no pruning, evergreen and attractiveness for front border. Will they stay neat looking over time or do they get out of control? Some of your archives seem to indicate they are invasive, and makes me wonder if I should put them in large pots. Any advice is appreciated. Thank you.

Answer: In your gardening zone, Yucca recurvifolia is a 4-6' tall evergreen shrub with lance shaped recurving to arching leaves. The foliage is more blue green than most Yucca spp. Soft Leaf Yucca is generally a single stem in youth and can become multi trunked with age. The growth habit is rosette in youth, with age the plant can become tree like. This Yucca will bloom late summer to fall, the flowers are creamy white and bell shaped and are borne on 3-5' spikes. This shrub has excellent heat and drought tolerance. Desert Willows are equally drought tolerant and enjoy the same growing conditions so they should make good garden companions. Planting 4 feet from the fence should provide adequate room for the plants. I don't think you'll find them invasive.
