Perennial. This charming blend of dwarf delphiniums is an excellent choice for small spaces, or as an accent in the border or cottage garden. Prolific plants will bloom the first year producing marine blue, light blue, soft rose, or white flowers. Grows well in containers and spots where the wind might topple taller varieties. Unlike traditional delphiniums, the dwarf type is a native of China, and was first introduced to England in 1818.
