Plant information

New York ironweed comes by its name honestly, between the tough-as-nails plant characteristics and the rust colored seeds and rusty color of the fading blooms. While this plant is very tolerant of different soils, it prefers the rich soils of woodland gardens, with plenty of decaying leaf litter.

Slightly reminiscent of Joe-Pye weed, this tall perennial stands 4-6 feet off the ground and bears flat-topped clusters of deep lavender flower heads. Use this plant in the back of garden beds for the perfect backdrop.

New York Ironweed has moderate drought resistance and can tolerate clay soils. Along with being attractive to pollinators, this plant is also juglone tolerant (black walnut trees), so it can be planted in areas where that is a concern.

stratification code
C(60)

A	Seed should germinate when sown in a warm location.
B	Hot water treatment: Bring water to a boil, remove from heat, pour over seeds, and soak for 24 hours.. Generally this is for seed with a thick seedcoat.
C	(# of days of cold moist stratification) Seeds germinate after a period of cold, moist stratification. Mix seeds with a handful of damp vermiculite or clean sand (moist—but not wet). Place mixture in a sealed plastic bag and store in a refrigerator, NOT the freezer.

G	Highest germination rate in cool soil.
H	Seeds need scarification: One way this can be achieved is to rub the seed between two sheets of sand paper. If code "C" is also called for, scarify first.

J	Legume seeds (more info next year).
K	Parasitic species which needs a host plant.
