Also known as Butterfly Weed, Roberta’s Soulmate and Orange Cura produces large clumping flower heads that effervesce with an aroma similar to that of our favorite butterfly bushes, a wonderful floral vanilla fragrance. If you’ve ever wanted a butterfly garden, this collection is the perfect starting point. And these native perennials are winter hardy to -30F making them suitable for gardens just about anywhere in the continental US; not to mention once they are established, they are some of the most heat resistant plants in the garden. Roberta’s Asclepias are also courageously strong plants with thick, sturdy stems that can be used to support other weaker stemmed perennials in your garden. This six piece collection is a must have for every aspiring Cottage Garden or Meadow Garden bringing you effortless plants that thrive just about everywhere in America and blooming dense, fragrant flower clusters for a good long time every single summer.
