Delphinium 'King Arthur Group'

delphinium

Product Image
Spectacular spires of semi-double, plum-purple flowers, each with a white eye, appear in June and July above deeply lobed, mid-green leaves. These brightly coloured delphiniums look fantastic towards the back of a sunny, well-drained border. Shorter-lived than many other varieties of delphinium, they nonetheless make excellent and long-lasting cut-flowers.

How to care for Delphinium King Arthur Group:

For best results, plant in an open spot with fertile, freely-draining soil and protect the young foliage against slug and snail damage. During the growing season, apply a seaweed or balanced liquid fertiliser every 2-3 weeks. While wearing gloves, stake the emerging flower spike with a stout bamboo cane and tie it in as it grows. Cutting back the faded flower stems to a flowering side shoot will help encourage a second flush of flowers.
