Hemerocallis 'Bettylen' (Reblooming Daylily) is a compact perennial boasting a profusion of large, fragrant, purple flowers, 5 in. across (13 cm), adorned with white toothy edges above a green throat. Blooming in early to mid-summer, the attractive blossoms are held neatly above its compact mound of arching, linear leaves. Each flower typically lasts no more than 24 hours (thus the common name 'Daylily'), opening up in the morning and withering during the forthcoming night, possibly replaced by another one on the same scape (flower stalk) the next day. One plant can bear up to 15 flower buds for a long-lasting display.
