It is a wild ancestor of the carrot family and makes a beautiful mounded plant about four feet tall. The white flowers are borne in a compound umbel, generally flattened on top and having a tiny dark red flower in the center. It is excellent grown in the mid border and the ferny foliage along with its lacy flowers, is very pretty in floral arrangements. Usually they come up in the spring for 3 for 4 years and then disappear completely. Though I've seen potted plants in nurseries and garden centers, their cost is prohibitive.
Delphinium are the easiest and most beautiful of perennials that can be grown from seed.
Delphinium seed germinates in 20 days and the seedlings grow rapidly. Someone gave me what he called 'a ground cover' that grows like a small evergreen tree but has yellow-green blooms on the top of each stem. I do not know its botanical name but it is very useful for filling in areas that other plants dislike. You'll be glad you did.
