The flowers are excellent for cutting. Its deeply cut ferny compound leaves remain grayish green in color throughout the season.

Landscape Attributes

Chinese Delphinium is an herbaceous perennial with a mounded form. Its relatively fine texture sets it apart from other garden plants with less refined foliage.

This plant will require occasional maintenance and upkeep, and should be cut back in late fall in preparation for winter. It is a good choice for attracting bees, butterflies and hummingbirds to your yard. Gardeners should be aware of the following characteristic(s) that may warrant special consideration;

  • Insects
  • Disease
  • Self-Seeding

Chinese Delphinium is recommended for the following landscape applications;

  • Mass Planting
  • Rock/Alpine Gardens
  • Border Edging
  • General Garden Use
  • Container Planting

Planting & Growing

Chinese Delphinium will grow to be about 18 inches tall at maturity extending to 24 inches tall with the flowers, with a spread of 18 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 12 inches apart. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 3 years. As an herbaceous perennial, this plant will usually die back to the crown each winter, and will regrow from the base each spring. Be careful not to disturb the crown in late winter when it may not be readily seen!

This plant should only be grown in full sunlight. It prefers to grow in average to moist conditions, and shouldn't be allowed to dry out. It may require supplemental watering during periods of drought or extended heat. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. This species is not originally from North America. It can be propagated by division.

Chinese Delphinium is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. It can be used either as 'filler' or as a 'thriller' in the 'spiller-thriller-filler' container combination, depending on the height and form of the other plants used in the container planting. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
