English Monkshood

English Monkshood

Aconitum napellus 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 ⅓to ½ the spike is in bloom. I love watching bumblebees climb under the hood and completely disappear into the flowers then clamber out again covered with pollen.

The entire plant is poisonous; wear gloves and wash your hands after handling or cutting.

Performs best when planted under tall trees. Prefers partial shade. Plant 15-20" apart in moist soil. 36-40" tall. Z3. (bare-root crowns)

Additional Information

Herbaceous Perennial Plants

When you receive your order, open the bags and check the stock. Roots and crowns should be firm and pliable. If they are slightly dry, add a little water or, if they are going to be potted up soon, wet the roots. Generally, a little surface mold is harmless and will not affect the plant’s future performance. If you cannot pot them up immediately, store them in a cool (35–40°) location for a short time.

Do not plant bare-root perennial plant crowns directly outdoors.

Pot up the rootstock using well-drained potting mix in a deep 6" pot or a 1-gallon container. Avoid coiling the roots in under-sized containers.
Grow newly potted perennials for a few weeks in a protected location in indirect light at 50–60°. Wet and/or cold conditions for an extended period may cause rotting.
Transplant outside once they show some top growth and the danger of frost has passed.
