Eight-stamen pokeweed (Phytolacca octandra) belongs to the Phytolaccaceae family within the Phytolacca genus. Eight-stamen pokeweed is native to the Neotropical realm of the Americas.

Eight-stamen pokeweed displays an upright, bushy shrub growth habit, reaching up to 3 ft tall with a spread of approximately 2 ft. Eight-stamen pokeweed produces small clusters of white or pink flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Eight-stamen pokeweed every 7–10 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established shrubs mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Eight-stamen pokeweed thrives in full sun to partial shade.

Phytolacca octandra tolerates temperatures of 65–80°F. Eight-stamen pokeweed prefers humidity levels of 40–60%.

Moist, well-draining soil with high organic content. Good drainage is essential for Eight-stamen pokeweed to prevent waterlogging, which leads to root rot and fungal issues.

Feed Eight-stamen pokeweed every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established shrubs in good soil often need little extra feeding, so let weak growth or pale foliage guide you.

Stop feeding by late summer so new growth can harden before winter.

Plant container-grown or balled-and-burlapped shrubs in spring or early autumn, setting the root flare at soil level, and water well after planting.

Eight-stamen pokeweed can spread to about 2 ft (0.6 m) and reach about 3 ft (1 m) tall. Space plants about 2 ft (0.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Eight-stamen pokeweed while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.

If it flowers in spring, prune right after flowering instead so you don't remove next year's buds. Never take off more than about a quarter of the shrub in one year.
