General Description

The Pennant Series of delphinium is a collection of elatum-type larkspur known for densely lined flower spikes that don't need staking. This short-lived herbaceous perennial is a hybrid. Its deeply lobed, green foliage is accented by a showy display of semi-double (extra petals) flowers, on sturdy, medium-tall spikes from late spring to midsummer. Butterflies and hummingbirds will visit the blossoms, called florets.

Delphiniums can grow in a variety of soil types but excel in fertile, well drained, slightly alkaline soil and full sun. They endure best when not exposed to excessively warm temperatures. Pennant Series plants are unsurpassed for cutflowers, as well as border or bedding plants and perform well in containers, even in windier situations. Once the flower spike has finished blooming, cut it back to where the smaller flowering shoots are forming. A reblooming also may occur by early autumn. Contact with the leaves can cause skin irritation in many people. Monitor the young foliage for attacks from snails and slugs.
