As deeply dark as the night sky! ‘Cosmos’ is the darkest Dierama out there, giving a richer & more stunning visage to a plant that’s already over-the-top lust-worthy & dramatic. Come Summer, when the Dieramas begin their reign over the garden, there’s not a soul in the nursery who isn’t swayed by their delicate yet impressive display – a 3-4’ abundance of long, thin dancing stems decked with myriad bells. Dieramas hail from the Eastern Cape of South Africa where rainfall occurs in the Summer, but they still thrive here in California. Once established, they’re drought tolerant & evergreen, needing only occasional grooming (just pull the spent leaves & cut down faded flower stems, & top dress annually when the plants are in growth.) Especially heavy soils should be amended for drainage.
