Asclepias incarnata 'Soulmate' (Swamp Milkweed) lights up the mid-to-late summer garden with clusters of pink petals surrounding a white heart. This native star attracts and nourishes hummingbirds, butterflies, bees, and pollinators of many shapes and sizes – especially Monarch butterflies. With a sweet vanilla scent, it’s deer and rabbit resistant. This easy-care plant brings as much pleasure to the gardener as it does to the pollinators in sunny borders and meadows with average-to-moist soil.

Description

Asclepias incarnata 'Soulmate' (Swamp Milkweed) has cheery bright pink flowers and upright stems with long green leaves. It stands at 3-4' tall and is a worthy addition to a sunny border or meadow garden, where this easy-care perennial can provide sweetly scented flowers from mid-to-late summer. Swamp milkweed likes moisture and will tolerate clay soil as well. With a broad native range, Asclepias is a very important plant for the monarch butterfly – it is the host plant essential for the survival of monarch caterpillars, and an important nectar source for mature monarch butterflies. Consider planting several species such as Asclepias tuberosa, A. syriaca, and A. purpurascens to provide plenty of variety for monarchs and non-stop garden color from June to September.

Planting & Care

Asclepias (Milkweed) are sun loving plants that are essential perennials for monarch butterflies providing food for caterpillars and nectar for adult butterflies. They bloom from mid-summer into early fall and, with their milky sap, are resistant to rabbits and deer.

Asclepias can be divided into two groups for plant care; Asclepias tuberosa with orange (sometimes yellow) flowers and all the other species with pink (sometimes white) flowers.

  • Asclepias tuberosa (Orange Butterfly Weed) - this perennial stays dormant until later in the spring than many other plants, especially when grown in pots. It's fine to plant dormant plants; don't up-pot them for planting later in the growing season.
  1. Need sandy or gravelly soils (except the Clay form which does well in heavier soils including dry clay.)
  2. Does best with gravel mulches.
  3. After their second growing season, only requires deep but infrequent watering. Plant in full hot sun.
  4. Just a few handfuls of compost and Yum Yum Mix added to the planting hole is enough. Don't plant into a rich, highly-amended soil.

Special comments:

  • When planting dormant plants, water thoroughly after planting and wait to water again until the plant comes into active growth, at which time a deep watering every week or so is adequate. Take care not to overwater young transplants.
  • Asclepias has a long, carrot-like tap root that should remain undisturbed after planting and should NOT ever be divided.

Most Asclepias species are late to wake up in the spring, and will often be shipped as dormant plants. Don't despair if your milkweed is asleep. The white roots and woody crown are alive just waiting for consistently warm weather to wake up and begin to grow.these perennial species stay dormant later in the spring than many other plants, especially when they are grown in pots. It's fine to plant dormant plants; don't up-pot them for planting later in the growing season.

Preferred growing conditions:

  1. These species grow in a wide range of soil types, including clay.
  2. They don't need mulching (except in very hot climates).
  3. These are moisture-loving perennials and do well in wet to moderately moist soil conditions.
  4. Plant in full to part sun areas.
  5. They like compost enriched soils at planting time.

Special comments:

  • Asclepias syriaca and A. speciosa will spread to make big patches of plants and are best planted in parts of the landscape where they won't crowd out less vigorous plants. Not recommended for the prime spots in your perennial beds.
  • Asclepias incarnata (Swamp Milkweed) is a more refined grower and is fine to include in perennial beds.

Oftentimes, Milkweeds won't grow much their first season in the ground, so be patient. They are establishing their root system and crown. By the second growing season, the plants will begin to get bigger and look more robust. Asclepias species are an odd bunch and don't behave like many other more familiar perennials. So be patient and accept their quirky nature.

Garden care:

  1. Fertilize Asclepias just once in fall with Yum Yum Mix and Planters II. - Naturalized plantings don't need additional fertilization.
  2. To encourage re-seeding and provide winter interest with their ornamental seed pods, leave the stems intact over the winter. In mid-spring, remove old stems just above ground level.
  3. All species of Asclepias are late to emerge in the spring, so don't be concerned if other perennials come up first and they remain dormant.

Beautiful plant!

"The plants are TOP quality! Currently, I have them in a big outdoor pot until I decide on their permanent location. They already are over 3 feet tall and beginning to bloom. I can't wait to enjoy their fragrance! I have been looking for this particular variety and High Country Gardens came through! You will not be disappointed with your purchase. I also bought sweet peas which are fabulous and beginning to bloom. THANK YOU HCG for offering a variety of hard to find perennials…. will order again and again. I have no cons so far…."

— Kathy (5/5)

Healthy plant.

"The plant arrived in very good shape and was a substantial size. It's already doubled since I planted it a few weeks ago."

— DWD (5/5)

Healthy plant

"So, at first I recieved the wrong plant, but I contacted High Country and they sent the correct plant right away. It started very small, but grew extremely quickly and is already about to bloom. I didn't think it would bloom first year, but it turned out to be a fast grower. I planted it at the edge of my marsh pond, and it loves it there in it's sunny, moist location. I'm very happy with this Soulmate Swamp Milkweed, and would buy again1"

I have a black thumb

"I have a black thumb but I am trying to learn gardening. I was so excited when my swamp milkweed started growing but then the leaves started turning yellow. Eventually, all the leaves fell off. I'm afraid I killed it but I'm hoping that there is some way I can bring it back. I really want to create a garden that attracts hummingbirds and butterflies."

"This plant is very happy. No blooms yet however I might have to wait a year for it to blossom."
