Delphinium

Overview

An herbaceous perennial of the buttercup family that is native to clearings, woodland margins, and river valleys from southern and central Europe to Siberia.

Water

Water deeply during rainless periods, but don't allow standing water. Delphiniums like it moist, but water that lingers causes crown and root rot. Water delphiniums at the base, keeping the foliage dry to help prevent disease.

Light

Delphinium plants require 6 to 8 hours of sun a day, and gentle morning and early afternoon sun is preferred. The roots need cool, moist shade.

Soil

These plants require excellent drainage. In poor or heavy soil, add organic matter at planting time to improve drainage. Delphiniums love fertile, rich, moist soils.
