Delphinium Highlander Sweet Sensation


Raised in Glasgow (hence the name) this Celtic beauty is much hardier than your average Delphinium. Many large, unusually frilly, triple rosettes are held high on strong stems during summer. Good for cutting, happy in borders and containers. Prefer well-drained soil in sun. 
Height 90cm (36"). Spread 40cm (16"). Fully hardy perennials supplied in 7cm pots.

Additional Information

The plants when fully grown may need staking for support. In growth water all plants freely, applying a liquid fertiliser every 3-4 weeks. Dead-head by cutting back spent flowers spikes back to small flowering side shoots. Cut back all growth to the ground level after it has withered in the autumn. All parts may cause severe discomfort if eaten and contact with foliage may irritate skin. Propagate by sowing seed in the spring. Hardy perennial. Young plants are attractive to slugs, may need protection until bigger.

"Thank you ladies for your beautiful plants.
Praise also, for the Bulrush Compost, of which I have purchased 8 bags during the past six months. It is superb and my garden has flourished.
Bless you,
Kind wishes"
