This grew well for me in silty soil of pH 7.0.

I liked the plant well enough---the lacy foliage is especially fine--- but it holds on to its flowers as they turn brown and for long afterwards. Unless you deadhead religiously, the impression left by the dead flowers overwhelms the fresh ones, and it all winds up looking weedy. With some reluctance, I composted mine and weeded out the seedlings. (It does self-sow.)

According to BONAP, it's range is in 23 states, from Minnesota and Iowa east to Maine and south to Tennessee and North Carolina. It's extirpated in IN and DE, present and not rare in PA, NY, and CT, and rare in the other 18 states. According to the USDA, it is endangered or threatened in 8 states.

The Korean species is A. asiatica, who... read more

Easy to grow once it decides to germinate seed. An unusual biennial vine, it looks like a robust corydalis in it's first year, then takes off in the second. Very delicate stems grow rapidly and large, bloom all summer.

Seed does not store well and germination is best with fresh seed. Germination may take several months or longer. For me, in Seattle area, seed sown in fall germinates sporadically during the following early summer. Because it's biennial and the seed loses viability quickly, I've only had plants every other year.

Very nice combined with golden bleeding heart vine, Dicentra scandens.

This plant started growing next to an unused chimney at my home. It gets to be a very large vining plant with lots of little pink flowers that look like elongated, skinny bleeding hearts. Inside each flower a seed pod develops and tiny little black seeds can be harvested.
I have just let it grow back and self seed each year since it first appeared. It is a beautiful plant with delicate vines and foliage and profuse pink blossoms. I shared seeds with coworkers last year, but am not sure if they were planted or started to grow yet this year.
