Angelica gigas, or Purple Parsnip, Purple Angelica or Korean Angelica, was introduced to North America by Barry Yinger, one of the principals at Asiatica Nursery, a cool mail-order company based in Pennsylvania. It is native to Japan, Korea and China.
It is usually listed as a biennial, although seedlings will take a couple of years to mature before flowering. It also self-sows readily in the garden under favourable conditions.
I've grown it in two gardens here in Niagara-on-the-Lake. It is definitely more striking in brighter light. It is also loved by the bees!
Here's to dirt under your nails.
