Dasylirion longissima a slow-growing evergreen succulent featuring a perfectly symmetrical crown of long, spineless, grass-like leaves and small, creamy-white flowers on a 9–15 foot stalk. Blooms infrequently and the stalk is highly durable and will remain standing on the plant for a year or more if left untouched. Uses include architectural focal point, xeriscaping and desert gardens, container, streetscapes, barrier planting. Exceptionally low water requirement once fully established. It requires porous, sharply draining, sandy, gravelly, or rocky soils. Highly prone to root rot in heavy clay or waterlogged settings. It prefers full sun for optimal dense, compact growth. It is only lightly shade-tolerant, becoming leggy and loose if light is insufficient. Fire-resistant. Resistant to Verticillium wilt. Deer and rabbit-resistant. Cold hardy to 15°F.
