Our Swamp Milkweed Collection is the perfect start to your butterfly garden, rain garden, stream bed, or anywhere you want to see beautiful flowers and pollinators in wet soil. Pink and white flowers on tall stems with lovely long green leaves look beautiful in large plantings, or paired with other tall perennials. In fall, look for plentiful silky-haired seeds. Asclepias incarnata (also known as Rose Milkweed) is a native perennial, and the sole host plant of Monarch Butterflies. In time, these deer resistant plants will spread and naturalize to help your pollinator garden grow! Collection of 3 plants.
The ‘Swamp Milkweed Collection’ features a trio of long-lived native perennials with pink and white flowers. Asclepias, or 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. 'Rose' Swamp Milkweed will spread more slowly that its relatives, making it a better candidate to include in traditional perennial garden beds. Milkweed can be slow-growing, and slow to wake up from dormancy in spring, but these long-lived perennials are essential for the survival of monarch butterflies, and long-lived once established! We highly recommend giving these beauties a place in your garden. Mature plants range from 36-48" tall x 24-36” wide.
Our Swamp Milkweed Collection comes with 3 plants (1 of each) and covers approximately 12 square feet when planted together.
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.
Preferred growing conditions:
Need sandy or gravelly soils (except the Clay form which does well in heavier soils including dry clay.)
Does best with gravel mulches.
After their second growing season, only requires deep but infrequent watering. Plant in full hot sun.
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.
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:
These species grow in a wide range of soil types, including clay.
They don't need mulching (except in very hot climates).
These are moisture-loving perennials and do well in wet to moderately moist soil conditions.
Plant in full to part sun areas.
They like compost enriched soils at planting time.
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.
Fertilize Asclepias just once in fall with Yum Yum Mix and Planters II. - Naturalized plantings don't need additional fertilization.
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.
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.
