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.

Herbaceous Perennial Plants
When you receive your order, open the bags and check the stock. Roots and crowns should be firm and pliable. Generally, a little surface mold is harmless and will not affect the plant’s future performance. If they are slightly dry, add a little water or, if they are going to be planted or potted up soon, wet the roots. If you do not plant or 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 before danger of frost has passed. Wet and/or cold conditions for an extended period may cause rotting.
Pot up 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°. Transplant outside once they show some top growth and the danger of frost has passed.
