Twisted leaf yucca is ideal for small spaces. This petite, stemless yucca forms a clump of about 2 feet tall by 2 to 3 feet wide. Its contorted bright green leaves twist and turn, giving this plant a distinctive form. It produces 5-foot-tall, open spikes of creamy white flowers in the late spring and summer. Native to central Texas, this yucca is often growing under mesquites and oaks' broken shade. Twisted leaf yucca thrives in full sun to part shade, provided the soil is well-drained. Yucca rupicola hybridizes readily with Yucca pallida, resulting in seedlings with green, twisted leaves. Twisted leaf yucca is hardy to -10º F.
