With its large 7-8” gold-dusted, tangerine orange blossoms, this exquisite variety demands attention. The narrow, twisted petals with loosely ruffled edges recurve for an appealing different look for this award-winning Daylily.

A taller selection, the American Hemerocallis Society awarded this show-stopper with the President's Cup for overall best cultivar at the National Convention in 2013. This multi-award winner also received the Stout Silver Medal in 2003, the Lambert Webster Award in 2001 for 'Best Unusual Form', the Award of Merit in 2000 and an Honorable Mention in 1997. Hemerocallis Primal Scream, a tetraploid, was selected for its abundant blossoms and hardiness in a variety of climates and soils. Drought tolerant once established. Each Hemerocallis flower unfolds for a day – thus the common name – only to be replaced the next day with a fresh, beautiful blossom, providing weeks of gorgeous color.
