In the garden
Delphinium 'Nora Ferguson' belongs to the genus Delphinium in the Ranunculaceae; the genus contains around 300 species native across the Northern Hemisphere and on the high mountains of tropical Africa, and was named by Carl Linnaeus. Within that broad group are both short-stemmed prairie species and tall, many-flowered forest species, and cultivars carry those upright, spike-forming habits into garden borders. Flowers appear in the UK from June to August, producing the elongated racemes associated with Delphinium. The foliage of the genus is palmate and deeply lobed, typically with three to seven pointed, toothed lobes. As members of the Ranunculaceae, delphiniums contain toxic compounds, so position plants away from grazing animals and exercise caution when pruning or removing spent stems. In a UK planting scheme, Delphinium 'Nora Ferguson' will supply tall summer spikes that sit above many herbaceous perennials and contribute vertical structure to mixed borders or designated cutting areas. Expect flowering through June to August and remember that all Delphinium are toxic to humans and livestock, so handle and site the plants accordingly.
