4' x 4'wide, (seed grown). Sotol is one of my favorite sculptural plants for the western garden. Its strap-like, blue-green leaves are evergreen and create a stiff, almost grass-like effect. The leaf edges have finely-toothed margins that light up when the low-angled sun shines through. Our seed comes from the Ring of Fire State Park in central NM, probably the most northern and cold-hardy population of this species. In zones 5 and 6, plant against warm walls in a protected site and give the plant extra winter protection for the first couple of winters; Dasylirion is quite cold hardy when well established. Zones (5) 6-10.
