DIERAMA ANGEL'S FISHING ROD, WANDFLOWER. In general, they like full sun in a well drained soil and perform best with ample summer water. They'll thrive in zones 8 and warmer in a rich soil like most other plants, but can potentially lose winter hardiness. Unfortunately Dierama are fickle, regardless if zone 7 or 8, and about 2/3 of our attempts to get them established in the ground failed. The best spot so far was our worst soil we could offer; rocky/sandy mixed in with dirt of lesser reputation. Absolute must is good drainage. If not sure, plant on a berm, the only way we can grow them. As far as taking the cold, we had some in 4" pots surviving 8°F with minimal protection. Either way, we recommend to experiment with lesser expensive Dierama first before you get into the more expensive selections.
