DELPHINIUM
All flower MAY-JUN
Another old cottage-garden favourite. To get the best display requires some fussing over. Greedy feeders and loved by slugs. Taller varieties need staking. Results can be spectacular.
Genus of about 320 species of annuals, biennials and perennials found mainly in mountainous areas worldwide, except Australia.
Main delphinium, or larkspur, cultivars are classed into Belladonna, Elatum or Pacific Hybrid groups
