  • Vigorous

A statuesque perennial for the back of the border but a stunner when well grown. Large, pure white flowers with papery petals surround golden yellow centres and are held above blue-green, fern-like foliage. Flowers are produced on mature plants from mid-summer until autumn and are a magnet for pollinating insects.

Prefers a fertile, well-drained soil in full sun. May take a while to establish. Shelter from strong winds and once planted leave alone as it resents disturbance. When established this is a vigorous plant which requires room to grow well.

Height: 24 - 96 inches  / 60 - 240cm

Spread: 36 - 108 inches / 90 - 180cm

Lynne's notes:

This is an absolute stunner and a plant that would definitely be in my top 40. It's not one for the feint hearted and needs room to grow but it's well worth it. Always popular with our customers I definitely know why.

Delivery Options

Our web shop is now open for you to browse and make your selection from. Postage and packing charges depend on the total weight of plants you buy. We only send plants out Monday (not Bank Holidays) to Wednesday. This is to avoid packages being left in the postage system over the weekend. Shipping plants and keeping them healthy along the process is an intricate matter. As we care for the plants we sell we deliver them in a way that ensures they have enough to drink and enough protection between our nursery and your home.
