Delphiniums are perennials grown for their showy spikes of colorful summer flowers in gorgeous shades of blue, pink, white, and purple. They are popular in cottage-style gardens and cutting gardens.
Delphiniums are a favorite of many gardeners and sometimes a challenge. They prefer moist, cool summers and do not fare well in hot, dry summers. The plants also dislike sudden wind or rain.
Except for the dwarf perennials, most delphiniums need staking.
