Asclepias incarnata, Rose Milkweed, is also commonly called Red Milkweed, Marsh Milkweed, or Swamp Milkweed.  That lovely vanilla fragrance you detect coming from large rosy pink flowers possibly hosting several Monarch or Swallowtail butterflies is Rose Milkweed. Like all members of the Asclepias genus, this milkweed is often used by monarch butterflies as a host plant.

This deer-resistant plant grows best in moist but will tolerate average soils, and blooms for about a month mid-summer.  Later, large pods form which will break open to reveal seeds that will float away in the wind. If growing Rose Milkweed from seed, try fall planting - or if planting in spring be sure to first moist-cold stratify the seeds for a month.  Large numbers of Rose Milkweed can often be seen growing in wetland settings.

5 Questions asked on Asclepias incarnata

Does Rose milkweed have a deep root system?
Hi Rich, According to MonarchWatch.org, "Some are shallow rooted but known to have taproots of 18 inches or more."
Do monarchs use this plant to lay eggs on? I saw your response to this question on the tuberosa variety- that they will leg eggs on the butterfly weed, asclepias tuberosa, but it isn't their first choice. It made me wonder how this variety compares. I assume that common milkweed is the first choice. Is this true? I want to plant the varieties that have the greatest likelihood of acting as host.
You are correct, the Asclepias syriaca (Common Milkweed) is their first choice to lay eggs on. They much prefer that species to any other Asclepias. That being said, they will still inhabit the Asclepias tuberosa (Butterfly Weed) and Asclepias incarnata (Rose Milkweed) and lay eggs on if need be.
Does this variety spread (rhizomatous) or move around (self seeding)?
Hi Kyle. Rose Milkweeds are prolific self-seeders. They often have deep taproots and are less likely to spread in that way.
Is Rose Milkweed salt tolerant? I'd like to place it in my adopted roadside space, if it is.
Hi Rebecca. The vote is still out whether Rose Milkweed is salt tolerant - and to what extent. This species has proven itself to be incredibly adaptive; we think it would be well worth the experiment!
My Rose Milkweed is on year two! First year was great, this year it is wilting stem by stem starting at the flower buds. It looks sick, how do I prevent further disease? Or are these milkweed plants a lost cause?
Hi Kaitlin. Would you mind sending some pictures of the distressed Rose Milkweed plants to [email protected]. Our greenhouse staff can hopefully identify what might be the issue and help troubleshoot. From the description, it may be insects causing the problem or possibly environmental effects. After taking some photos, you may want to remove the sickly plant material and dispose of it.

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 species don't need any pre-treatment to germinate, but some species have dormancy mechanisms that must be broken before the seed will germinate. 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.

Dormant Bare Root Plants

We dig plants when they are dormant from our outdoor beds and ship them April-May and October. Some species go dormant in the summer and we can ship them July/August. 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

3-packs and trays of 32, 38, or 50 plants leave our Midwest greenhouses based on species readiness (being well-rooted for transit) and order date; Spring shipping is typically early May through June, and Fall shipping is mid-August through September. Potted 3-packs and trays of 38 plugs are started from seed in the winter so are typically 3-4 months old when they ship. Trays of 32/50 plugs are usually overwintered so are 1 year old. Plant tray cells are approximately 2” wide x 5” deep in the trays of 38 and 50, and 2.5" wide x 3.5" deep in the 3-packs and trays of 32; ideal for deep-rooted natives. Full-color tags and planting & care instructions 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.

US Shipping & Handling Charges

SEED $100.00 and under: $5.00
Retail SEED orders over $100.00 ship free!

Custom seed mixes or discounted seed sales over $100, add 5% of the total seed cost
(for orders over $1,000 a package signature may be required)

BARE ROOT and POTTED PLANTS $50.00 and under: $9.00
over $50.00: 18% of the total plant cost. (For orders over $1,000 a package signature may be required.)

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

**We are required to collect state sales tax in certain states. Your state's eligibility and % will be calculated at checkout. MN State Sales Tax of 7.375% is applied for orders picked up at our MN location. Shipping & handling charges are also subject to the sales tax.

Shipping Season

SEED, TOOLS and BOOKS are sent year-round. Most orders ship within 1-3 business days.

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 32/38/50 plugs and 3-packs) typically begin shipping early May and go into June; shipping time is heavily dependent on all the species in your order being well-rooted. If winter-spring greenhouse growing conditions are favorable and all species are well-rooted at once, then we ship by order date (first come, first serve). We are a Midwest greenhouse, and due to the challenges of getting all the species in the Mix & Match and Pre-Designed Garden Kits transit-ready at the same time, we typically can't ship before early May. Earlier shipment requests will be considered on a case-by-case basis.

*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. We send tracking numbers to your email address so please include it when you order.
