Overview
Although Delphinium are perennials, they are often treated as annuals with the seed companies encouraging gardeners to sow new seed every year when it isn't really necessary.
Statuesque in appearance, they have grey green fern like foliage which is largely inconspicuous because of the spectacular flower covered spikes which command absolute attention.
The flowers are up to 6cms across and tightly packed, usually blues, mauves and lilacs but some are available in pinks, creams and whites.
They are a perfect choice for the middle to rear of a mixed border, though due to their height they can require some support when in heavy bloom.
Soil: Well drained soils with plenty of added organic matter and a layer of mulch to retain moisture.
Some lime will also help.
Maintenance: Mulch to maintain moisture, liquid fertilise once a month until buds set.
Stake taller plants if in a windy location.
Diseases: Slugs, snails and powdery mildew.
Toxicity: Delphiniums are toxic, especially the younger parts of the plant. If ingested it can cause severe digestive issues and can cause severe skin irritation if touched.
All parts of the plant contain toxins including methyllycaconitine. Even the seeds are poisonous with a 1.4% content of alkaloids.
Other Species: 250 species in the genus but most garden delphiniums are derived from this one.
Other main ones include D. Pacific hybrids and Delphinium belladonna.
Comments: Delphiniums grow best in cooler climates.
