33 Best Types of Delphinium To Grow

Spread the love

Delphiniums are flowering plants that belong to the genus Delphinium and are a part of the buttercup family Ranunculaceae. There are over 350 species of delphinium; however, the garden varieties grown today have been heavily bred and cultivated and mostly belong to the groups Delphinium x elatum, Pacific Hybrid (or Pacific Giant), or the Belladonna group. 

Delphiniums are particular favorites for cottage-style or informal gardens and even have the nickname “Queen of The Border” in England due to their popularity as border plants. Many varieties are attractive to pollinators, making them a great fit for pollinator gardens. 

They are perennials that are hardy to USDA zones 3-7, however, Pacific Hybrid delphiniums are often grown as annuals or biennials. Flowers can be single or double, and come in a range of wonderful colors and color combinations! These include pink, red, yellow, white, purple, and blue! 

Delphinium flowers require a little maintenance to keep them happy and looking at their best, but this hasn’t stopped them from being a top choice among many gardeners!
