Hemerocallis 'Stella de Oro'
Yellow flowers are profuse in early summer, followed by waves of reblooming into early fall especially if spent blooms are removed.
Daylilies can survive many harsh conditions that other plants cannot such as: polluted city environments, slopes, poor and dry soils, near pavement that is salted in winter, and under Black Walnut trees (not affected by juglone).
Also may be called Stella d'Oro
