Tips For Growing Milkweed/Butterflyweed (Asclepias)

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.

1. 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.

  • 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.
  • ust 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.
  • 2. Asclepias speciosa, A. syriaca. A. incarnata (Milkweed) - 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.
  • 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.
  • Garden care:

    • 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.

      Comments about High Country Gardens Asclepias incarnata:

      Very pleased with this -- which has taken off in the second year. Lots of different pollinators like the blooms, mostly bumblebees here, but I have seen a lot of other things visiting the flowers, too. Including at least one monarch butterfly, the first one I have seen in my life.

        Q & A

        Suggested Companion Plants:

        USDA Hardiness Planting Zones

        To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.

        • If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
        • If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).
