Delphinium Seeds - Tall Cliveden Beauty

25+ Seeds

Cliveden Beauty is the hardiest delphinium, known for its first-year flowering and graceful sky-blue blooms that can reach up to 60 inches high. The well-branched plants produce long, slender stems with a delicate, airy appearance, making them a popular choice for bouquets and floral arrangements. 

While the tall plants may require support, especially in windy or rainy conditions, they attract bees and butterflies. Often grown as an annual, Cliveden Beauty is a perennial in Zones 3-7.
