In Southern California, it starts shooting up leaves once the fall rains start (October through December), although it seems to tolerate summer irrigation without issue. Usually blooms in the middle of winter (January), then by about early June, leaves die off and it's dormant until fall.

Spreads readily, but not too difficult to dig up or even yank up if the soil is moist enough.

My chasmanthe bloomed this year! I guess it finally got the right conditions. The blooms are a vivid yellow - stalks about 4 feet high. Hopefully this is going to be the start of a yearly bloom cycle.
