Delphinium glareosum is a species of larkspur which grows in Oregon, Washington, and British Columbia. It is in the Ranunculaceae. These plants favor rocky slopes. They flower in summer. Like all members of the genus Delphinium, rockslide larkspur is poisonous.
How to keep Delphinium Glareosum.
Water
Olympic larkspur requires consistent soil moisture for healthy flower growth. During dry periods, make sure to water the plants thoroughly, keeping the soil damp to a depth of at least 2.5 cm (1 inch) below the surface. Be careful not to overwater, as this can lead to root and crown rot.
Pruning
Olympic larkspur features tall flower spikes and vibrant colors. To promote strong growth and prolong the blooming period, prune the plant in early spring. Removing dead stems also improves air circulation and reduces the risk of disease. After the flowers have bloomed, cut back the blooms to encourage bushier growth, which enhances the plant's overall health and appearance.
