The Q&A Archives: Re: Larkspur

Question: Hi...

Are Larkspur and Delphinium the same flower or is there a difference? I saw a larkspur about 14 inches high in a store and it was gorgeous. How do you plant one and take care of a Larkspur?

Thanks a lot.. Dorian

Answer: Larkspur (Consolida ambigua) is sometimes called annual delphinium, and used to be classified as Delphinium ajacis. Whereas perennial delphinium (D. elatum) is a different genus and species, although it is sometimes called candle larkspur. Confusing isn't it! However, they do look similar and both are from the Ranunculaceae family. Larkspur take full sun and are easy to start from seed in garden soil. Sow in fall for growth in spring. Or, set out transplants in spring after the last frost. Once established, they self-sow from year to year. Some do very well in hot weather. They come in a range of colors, including blue, pink, rose, white and lilac. Good luck with your larkspur.
