Korean angelica (Angelica gigas) produces broad foliage clumps in its first year. The clumps shoot up into stout, 5- to 6-foot-tall, deep purple flowering stems in the second or third summer, with plump buds that split open to reveal domed, deep reddish purple flowerheads. The heads are often loaded with wasps, bees, and other pollinators. (The wasps may sound like a bad thing, but they’re so busy haunting the flowers that they’re unlikely to bother any respectful garden visitor. And anyway, the plants are so tall that you’ll keep them toward the middle or back of a border, where no one is likely to get too close to the flowers.)
Korean angelica pairs handsomely with summer-blooming shrubs, such as hydrangeas; upright ornamental grasses, such as ‘Karl Foerster’ feather reed grass (Calamagrostis x acutiflora); and tall flowering perennials, such as Culver’s root (Veronicastrum virginicum), ‘Lemon Queen’ perennial sunflower (Helianthus), and white Japanese burnet (Sanguisorba tenuifolia var. alba). It can make an interesting cut flower in a large arrangement, too, if you can bear to remove it from your garden display. Full sun to light shade; average to moist soil. Biennial or monocarpic perennial; Zones 4 or 5 to 9.
Collected in early October 2020. At least 20 seeds.
