Aconitum Lamarckii

Attention plant hunters! This dangerous but beautiful, bought on sight, plant forms 1.2m tall stately spires decorated in hooded, sherbet-lemon yellow flowers from June to September.

Preferring sunny sites with moist, fertile, free-draining soils, this rare yellow monks hood forms mounds of healthy, deeply-cut leaves, which look striking when planted with contrasting plants like Hostas, ferns and Bergenias.

This plant is best in the border where it can slowly self-seed.

"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"
