Care

Pokeweed thrives in full sun and well-drained soil, tolerating a variety of conditions. It's a resilient plant that requires minimal care once established, though it can spread readily.

Watering
Water regularly when young; established plants are drought-tolerant.
Feeding
Generally does not require fertilization; can be fertilized lightly in spring if desired.
Pruning
Prune in late winter or early spring to remove dead growth and shape the plant.
Repotting
Rarely needs repotting due to its perennial nature; can be divided if overgrown.

Safety

People
Ingestion can cause severe gastrointestinal upset, including nausea, vomiting, diarrhea, and abdominal pain. Large doses can lead to more serious symptoms like convulsions and respiratory distress.
Pets
All parts of the pokeweed plant are toxic to dogs and cats if ingested, causing symptoms like vomiting, diarrhea, and abdominal pain.
Children
This plant is highly toxic if ingested, and children are particularly at risk due to their smaller size. Keep children away from all parts of the plant, especially the berries.
Contact allergens
The sap can cause skin irritation in sensitive individuals.
Airborne allergens
Pollen may cause respiratory irritation or allergic reactions in some people.
Edibility
All parts of the plant are toxic, especially the roots and seeds.

Common problems

  • Aphids Small, soft-bodied insects that feed on plant sap, causing distorted growth.
  • Root rot Fungal disease favored by poorly drained soils, leading to wilting and plant death.
  • Leaf spot Fungal or bacterial infections causing spots on leaves, often in humid conditions.

Growing it

Propagation
Seed, Division
When to plant
Spring, Fall
Overwintering
In colder climates, the above-ground growth will die back in winter. Mulch the base of the plant to protect the root system. In milder climates, it may remain semi-evergreen.
In containers
Not well-suited for containers due to its large size and deep taproot; it prefers to grow in the ground.

Seed

  1. Collect seeds from ripe berries in late summer or fall.
  2. Remove seeds from the fleshy pulp and rinse them.
  3. Sow seeds in a pot or directly in the ground in the fall or early spring.
  4. Provide consistent moisture and a sunny location for germination.

Root Cuttings

  1. In early spring, carefully dig up the plant and divide the thick taproot.
  2. Cut sections of the root, ensuring each piece is a few inches long.
  3. Plant the root cuttings horizontally or vertically in moist, well-draining soil.
  4. Keep the soil consistently moist until new growth appears.

Plant it in a sunny spot where its vigorous growth won't be hindered, and pair it with other sun-loving, relatively tough perennials.

Grows well with

  • Sunflowers They share a similar preference for open, sunny locations and can tolerate a range of soil conditions.
  • Coneflowers These perennials also enjoy full sun and can help fill out the landscape around the more upright poke weed.
  • Goldenrod Goldenrods are excellent native companions that attract pollinators and thrive in similar sunny, open conditions.

Keep away from

  • Shade-loving plants Phytolacca americana requires full sun and will not thrive or may even be outcompeted in shady conditions.
  • Plants requiring consistently moist soil While it tolerates average moisture, it doesn't prefer constantly wet feet, which can lead to root rot.

Similar species

  • Pokeweed Very similar in appearance and toxicity, often considered the same species or a closely related variety.
  • Pokeweed Another related species with similar characteristics, though typically found in different habitats.

Questions people ask

Is Phytolacca americana poisonous?
Yes, all parts of Phytolacca americana are toxic to humans and most animals, though birds can eat the berries.
Can I eat poke sallet?
While young shoots were historically eaten as 'poke sallet' after careful preparation, it is extremely risky and not recommended due to the high toxicity.
What are the symptoms of poisoning?
Symptoms include nausea, vomiting, diarrhea, abdominal pain, and in severe cases, convulsions and respiratory issues.
Does it attract wildlife?
Yes, it's a valuable food source for many bird species and provides nectar for pollinators.
How do I get rid of it?
Due to its deep taproot, complete removal can be difficult; repeated cutting or digging is often necessary.

Where the name comes from

The genus name 'Phytolacca' comes from Greek 'phyton' (plant) and Latin 'lacca' (lac, a red dye), referring to the red juice of the berries. The species name 'americana' simply indicates its origin.

Good to know

  • Also known as poke sallet or poke weed.
  • It's a very fast-growing perennial.
  • Birds are generally unaffected by the toxins and eat the berries.
  • The plant has a deep taproot that can be difficult to remove.
