In the garden
Phytolacca americana is a perennial herb native to the USA that establishes as a tall, single-stemmed plant often reaching about 2.0 m. It flowers in the UK from July to September and is cultivated where its size and seasonal presence are acceptable. The species is listed as fully hardy in UK terms (H7) and is also rated USDA 4–8, so it tolerates a range of temperate conditions without winter protection. Plant it in a sunny spot; the species prefers full sun and soils that are moist but well drained, and it will grow in sandy, loamy or clay ground. Give plants room for their mature height and avoid densely planted, high-footfall sites because every part of the plant is toxic if eaten. When working with Phytolacca americana always use gloves and other protective equipment to reduce the risk of contact or accidental ingestion. Because of its stature, place it where it will not obstruct paths or be within reach of children and dogs, and allow a management plan for removing unwanted seedlings. The plant’s combination of size and toxicity means planning for its location is as important as its soil and light requirements.
