'Tardiva' and 'Endless Bummer' killed back to the ground second winter in a row. 'Annabelle', 'Blue Billow' and 'Limelight' are good. All on the east side of the house but the first two are more northerly than the last 3. All perennials are coming up fast with no problems other than that Corydalis 'Berry Exciting' is now blooming white. Is it a hybrid of C. ochroleuca?
