Asclepias tuberosa Butterfly Weed

* We are unable to ship PLANTS (bare root or potted) outside the contiguous US or to CA due to regulations.


Asclepias tuberosa, Butterfly Weed, is most often a distinctive bright orange but there is some variation in flower color, from deep red-orange to yellow. This distinctive color and the absence of the typical milky sap make identification easy.

Butterfly Weed needs a drier, well-drained location to successfully seed into and grow well. In older mature plants the long tap root can extend down a foot or more. They can be transplanted if dug carefully during dormancy but if enough root material is left behind they will regrow. The leaves are somewhat narrow, up to 1” and tapered, with no stem.

This is a great Milkweed for a sunny location in a dry area. Mature plants in ideal locations can make as many as 20 stems at an average height of 2’. The vivid orange color, low mounded profile, and ability to attract and sustain butterflies make this plant a well-known favorite for all types of gardens.

Dormant bare root plants ship each year during optimal transplanting season: Fall (October) or Spring (April/May).

Potted plants come in a tray of 38 plants and ship early May into June. Click here if you prefer to mix/match up to 6 species in a tray.

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.

*PLEASE NOTE: we are a mail order nursery and have no retail facilities, but you may pick up your order if prior arrangements are made. Pick up orders are subject to **MN Sales Tax.

Shipping & Handling Charges:
SEED $100.00 and under: $5.00
over $100.00: 5% of the total seed cost

BARE ROOT and POTTED PLANTS $50.00 and under: $7.50
over $50.00: 15% of the total plant cost

TOOLS and BOOKS have the shipping fee included in the cost of the product (within the contiguous US).

**MN State Sales Tax of 7.375% is applied for orders shipping to Minnesota only. Shipping & Handling Charges are also subject to the sales tax.

Shipping Season:

SEED, TOOLS and BOOKS are sent year-round. Most orders ship within a day or two upon receipt.

BARE ROOT PLANTS are shipped during optimal transplanting time: Spring (April-May) and Fall (Oct). Some ephemeral species are also available for summer shipping. Since our plants are field-grown, Nature sets the schedule each year as to when our season will begin and end. We fill all orders, on a first-come, first-serve basis, to the best of our ability depending on weather conditions beyond our control.

POTTED PLANTS (trays of 38) typically begin shipping early-May, based on order date and when all the species in the tray are transit-ready. We are a Midwest greenhouse and due to the challenges of getting all the species in the Mix & Match and Garden Kits transit-ready at the same time, we typically can’t ship before early-May.

*We are unable to ship PLANTS (bare root or potted) outside the contiguous US or to California due to regulations.

Delivery:

We ship using USPS, UPS and Spee Dee. UPS and Spee Dee are often used for expediting plant orders; they will not deliver to Post Office Box numbers, so please also include your street address if ordering plants.
