Delphinium grandiflorum

There are several popular cultivars in several colours which are grown as ornamental plants, including 'Blue Butterfly', 'Summer Morning', 'Blue Mirror', and 'Summer Stars'.

It is much shorter and more compact than the more familiar tall D. elatum, with dispersed flowers, rather than single spikes.

It is a short-lived perennial that is suggested to be treated like an annual in many cases due to its unpredictability in terms of returning the next season.

There are no lavender varieties, unlike with rocket larkspur (D. ajacis or consolida) and elatum plants.

Nursery-grown grandiflorum plants are readily available in the United States and can be found at stores such as Walmart and Lowe's.
