Vernonia noveboracensis New York Ironweed

Qty
Growing up to 7ft high, the purple flowers of Vernonia noveboracensis (New York Ironweed) tower over many other wildflower species of late summer and early fall, while providing nectar to foraging bees. The tall dead stalks remain standing well throughout the winter months, giving migrant bird species a place to perch in early Spring.

BONAP Map Key

This map shows the native and adventive range of this species. Given appropriate habitat and climate, native plants can be grown outside their range.

Seed:

Growing your own plants from seed is the most economical way to add natives to your home. Before you get started, one of the most important things to know about the seeds of wild plants is that many have built-in dormancy mechanisms that prevent the seed from germinating. In nature, this prevents a population of plants from germinating all at once, before killing frosts, or in times of drought. To propagate native plants, a gardener must break this dormancy before seed will grow.

Each species is different, so be sure to check the GERMINATION CODE listed on the website, in the catalog, or on your seed packet. Then, follow the GERMINATION INSTRUCTIONS prior to planting. Some dormancy can be broken in a few minutes, but some species take months or even years.

Seed dormancy can be broken artificially by prolonged refrigeration of damp seed in the process of cold/moist STRATIFICATION. A less complicated approach is to let nature handle the stratifying through a dormant seeding, sowing seeds on the surface of a weed-free site in late fall or winter. Tucked safely beneath the snow, seeds will be conditioned by weathering to make germination possible in subsequent growing seasons.

Bare Roots:

We dig bare-root plants from our outdoor beds and ship them April-May and October. We are among the few still employing this production method, which is labor intensive but plant-friendly. They arrive to you dormant, with little to no top-growth (bare-root), packed in peat moss. They should be planted as soon as possible. Unlike greenhouse-grown plants, bare-root plants can be planted during cold weather or anytime the soil is not frozen. A root photo is included with each species to illustrate the optimal depth and orientation. Planting instructions/care are also included with each order.

Potted Plants:

Trays (38 plants) leave our Midwest greenhouse based on species readiness (well-rooted for transit) and based on order date; shipping begins early-May and goes into June. Each of the 38 plant cells are 2” wide at top x 5” deep; ideal for deep-rooted natives. Full-color tags and planting instructions/care are included with each order.
