My very best performer this past summer was OKLAHOMA SAND BURR. It bloomed for a very long time, always had great color, even in very hot weather. I love the teeth on the sepals.
Some others that did well:
POLAR SNOW
TAL OF GASCONE
WINNING NOTE
TEQUILA MOCKINGBIRD - one of the best oranges I grow
IAN FLEMING
seedling - VIOLET BECOMES YOU X SOUTHERN DAZZLE
sibling to the one above - guess I should have added this one to the thread about watermarks on daylilies.
