Angelica atropurpurea (American Angelica) is a large herbaceous perennial with gorgeous, rounded umbels, up to 4-10 in. across (10-25 cm), of cream to greenish tiny flowers from early summer to early fall. The flower umbels are borne on smooth, dark purple, hollow stems. They rise above the foliage of bright green leaves adorned with 3-5 finely-toothed leaflets and make a pretty backdrop for other plants. The flowers give way to dry seed-like fruits. As an ornamental plant, Angelica atropurpurea is a stunning perennial, providing height and structure in the landscape. Its seed head stalks hold well into winter and are quite decorative.

  • Grows up to 3-10 ft. high (90-300 cm) and 2-6 ft. wide (60-180 cm). Individual plants can vary considerably in size depending on environmental conditions.
  • Performs best in full sun to part shade, in consistently wet to moist soils. Plants do best in the shadiest and coolest part of the garden, especially during hot summers. Standing water is well-tolerated. Staking may be needed in exposed sites.
  • Angelica is a welcomed addition to beds and borders, woodland gardens, naturalized areas, water gardens, bog gardens, and along streams or ponds.
  • No serious pest or disease issues. Deer resistant, it attracts butterflies and beneficial insects.
  • Plants may be grown from seed and may self-seed if spent flower umbels are not removed.
  • Native to central and eastern North America.
