At 15-20" tall, these hardy reblooming daylilies are perfect for edging borders and walkways as well as for patio containers due to their compact growth habit. Purple de Oro looks best when planted in clusters. They bloom first in early to midsummer and then produce a second wave of blooms in the fall. Hemerocallis 'Purple de 'Oro'
