Siberian larkspur

Water your Siberian larkspur (Delphinium grandiflorum 'Blue Butterfly') 1-2 times a week during the growing season and reduce watering during winter months when the plant is dormant. Water the soil deeply but infrequently so that the soil is evenly moist but not soggy. Make sure to water early in the day and avoid getting the foliage wet, as this can lead to disease.

Siberian larkspur, also known as Delphinium grandiflorum 'Blue Butterfly', thrives in sunny locations. It should receive 6-8 hours of direct sunlight each day, mostly in the morning hours. Exposure to afternoon sun should be limited, as too much sunlight during the hottest part of the day can cause the plants to become scorched. During the summer, the larkspur can benefit from a few hours of afternoon shade to protect it from heat stress. If planted in a shaded area, however, the Siberian larkspur's flowering period will be greatly reduced.

When to Prune: Siberian larkspur (Delphinium grandiflorum 'Blue Butterfly') should be pruned in late winter or early spring, just before new growth appears in March or April. How Much to Prune: They should be lightly pruned, removing any dead or diseased stems and deadheading faded flowers. If the plant becomes too tall, it can be pruned back by up to a third of its height. It is best to prune spring-blooming perennials such as Siberian larkspur before flowering, if possible.
