I've had Edith Wolford for years. It was one of the first named Iris I got.. It did better when I lived in Los Altos than it does here, although it's not as weak as some others..I sent a piece off with a friend, who lives in Seattle some years back. He sent me pictures every spring for many years. It apparently did very well there. Beverly Sills has been a wimpy grower for me so far.
And Greg, I thought I'd lost Song of Norway because it hadn't bloomed for several years, and the tag went missing.. Finally did this year, and I got another tag on it now. So far it hasn't made me fall in love with it.
