    Orange, orange, orange is the only way to describe the flower on Primal Scream. Always hot, hot orange. Large flowers on tall scapes. No way to not notice this one from across the garden.

    If you love orange blooms (and I do!), this is the one to get! If you don't, seeing this bloom in person may convert you. The distinct blooms are large with a tangerine and orange blend that really stands out and commands attention in the garden, especially in full clump size. Well loved by gardeners in a wide range of zones, it won the highest honor for a daylily in 2003, the Stout Metal.
