i think the zone info is incorrect as i am in Z9a and have these every year. they grow wild and come back no matter what the winter was like (sometimes in the teens) no matter how much or how little rainfall we get, no matter how hot the summers (110+ sometimes) i love them. a spot of color in the midst of all the chamise.

The range of the plant is from Washington to California, a very common wildflower in open grassy areas from
February to May.

It grows wild in my yard, moles and birds help spread it around. a very unobtrusive plant. Deer do like to munch on the flower heads just before they bloom.
