English Monkshood


English Monkshood

Aconitum napellus 36-40" tall.

Also called Friar’s Cap. Produces a mass of late-summer blooms with dense showy spikes of dark violet-blue helmet-shaped flowers held above elegant palmate foliage in late summer. Grand delphinium-style blooms rarely need staking. Forms large clumps in short order.

An excellent cutflower—cut when ⅓ to ½ the spike is in bloom. I love watching bumblebees disappear under the hood then clamber out covered in pollen.

The entire plant is poisonous; wear gloves and wash your hands after handling or cutting. Prefers partial shade. Plant 15-20" apart in moist soil. Z3. (bare-root crowns)

Additional Information

Herbaceous Perennial Plants

When you receive your order, open the bags and check the stock immediately. Roots and crowns should be firm and pliable. Surface mold is harmless and will not affect the plant’s future performance. Store plants in their packaging in a cool (35–40°) location until you are ready to plant. If it’s going to be awhile, you can pot up your perennials.

Do not plant bare-root perennial plant crowns directly outdoors before danger of frost has passed. Wet and/or cold conditions for an extended period may cause rotting.
