Spiny Sea Urchin is a California-bred daylily, registered in 2003. Blooms are 5.5" and it grows about 27" tall. The famous daylily "Ed Brown" is one of the parents of Spiny Sea Urchin. Ed Brown has been temperamental for me, too. It must be a Wisconsin thing...these plants are longing for California. With all the cold April rain and snow flurries we've had lately, I'd like a Cali vacation, too.
