Is wingstem invasive?

It can be aggressive in small gardens because it spreads readily by seed, but it is native to North America.

Does it need staking?

It can get quite tall, so planting it in a group or near sturdier plants helps keep it upright.

Safety

People: There is no significant toxicity reported for humans, but it is not intended for consumption.
Children: The plant is not toxic, but the tall, stiff stems can be sharp or abrasive if handled roughly by children.
Contact allergens: Handling the stems may cause mild skin irritation in sensitive individuals due to the texture.
Airborne allergens: The pollen can be a minor allergen for those sensitive to aster family plants during late summer.
Edibility: This plant is not considered edible and should not be consumed.

Growing it

Propagation: seed, division
When to plant: spring, autumn
Overwintering: The plant dies back to the ground in winter. You can leave the dried stems standing for winter interest and wildlife cover, then cut them back in early spring.
In containers: It is generally too large and aggressive for standard containers, but it can grow in very large tubs if kept well-watered.

Seed

1. Collect seeds in late autumn once the flower heads turn brown and dry.
2. Sow seeds directly into the garden in autumn for cold stratification.
3. Keep the soil moist until germination occurs in the spring.

Plant wingstem in the back of a border to provide height and structure for shorter, sun-loving perennials.

Good to know

Wingstem is a prolific self-seeder in ideal conditions.
It is a favorite of many native bees and late-season butterflies.
The stems carry thin leafy wings that run down from the leaf bases, a feature that sets wingstem apart from most other asters.
