Delphinium Plants

Think cottage garden, bees hovering in hazy sun around blue, mauve and pink flowers on vertical spikes up to 3ft, 4ft or even 6ft tall. Delphiniums are hardy perennials; plant out in full sun in May and June for flowers from July to September. Get ready to support the flower columns with stakes, harvest some for your vases and then cut the rest back for a second flowering.
