Growing & Maintenance Tips for Hemerocallis 'Happy Returns'
Hemerocallis grow best in an average to moist, well-drained soil, in full sun or partial shade. Daylilies with very dark flower colours benefit from more shade. They are adaptable to many soil conditions, even heavy clay soils and once established, will tolerate heat and drought. Prune the flower stalks down after blooming to improve the overall appearance and lengthen bloom time. They spread (some slowly, some more aggressively) by underground rhizomes. Easy to grow.
