Delphinium

Common Name: Larkspur

These tall, stately perennials are an old-time favorite but are relatively short-lived. Most prefer cooler climates and well-drained soils. Delphiniums are also heavy feeders and benefit from the addition of humus to the soil. Plants bloom early summer. Taller types have hollow stems and may require staking to protect from wind and rain. Plant near the back of the border.
