Dasylirion berlandieri is a cactus / succulent or shrub with green foliage. In summer flowers emerge. Grows well with sun and occasional - low water. Prefers to be dry in summer. Does well in well-drained soil.
Northern Mexican collection, now about 4 years old, from plants rather similar in appearance to D. wheeleri but of deeper blue and a more compact form. Extra filaments at the ends of the leaves make a dazzlingly golden halo when backlit. Not too fussy about water but provide good drainage and good air circulation especially in winter. Frost hardy to at least 10 °F to 15 °F; colder with good drainage.
