This monkshood is native to East Asia. It supports panicles of hooded flowers on plants that are reputedly upright. It didn't work out that way in their first year in our garden, during which they were shaded out by a magnificently full bleeding heart plant until mid-summer. Consequently, they grew lanky in search of light, and were laying down by the time their flowers finally opened. We'll try to put their habit to better use next year. According to information I've found, hot summers are difficult for this perennial – some afternoon shade is a plus.

Through the years, we've tried to grow quite a few species of Aconitum, but so far, this is the only one that has thrived in our garden, coming back bigger and better every year, in several spots around the garden with different exposures. I love how a mature specimen sends up a magnificent mound of its frilly leaves by early spring, and keeps looking mahvellous throughout the season, all the way till when it blooms in October.

In our garden, this plant grows in the following areas: side garden, front perennial border, Max's garden, pondside, back yard island, orchard nursery area, sale plot

Seed for this plant is included on my seed trade list
