Soapweed is a very drought-tolerant native plant. It grows as a rosette of long, sword-like blue-green leaves.
In mid to late summer, it produces the most beautiful stalks of showy, bell-shaped, greenish white flowers. After pollination, the flowers mature into woody seed capsules with large, flat black seeds.
Soapweed is the only host plant for the yucca moth. It should be planted away from pathways since the leave tips are very sharp.
Soapweed is a bold accent plant for hot, sunny gardens in the Colorado Springs area. Given the very sharp leaf tips, do not plant it near walkways, driveways, etc.
Remove spent flower stalk, if desired. Soapweed can be difficult to removed once established.
