I remember seeing this plant as the "European Plant of the Year" back in the 90s, and being immediately intrigued by its size, foliage shape and the colour of its stems and flowers.
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.
