Planting & Care

Where to Plant

  • Sunlight: Common Milkweed requires at least 6 to 8 hours of direct sunlight daily to thrive. While it can handle very light partial shade, full sun ensures the sturdiest stems and the maximum amount of nectar for visiting Monarchs.
  • Soil: This plant is famous for its adaptability and will grow in almost any soil, including heavy clay or poor, rocky ground. If your soil is extremely sandy and drains too quickly, mixing in some compost helps hold just enough moisture to get the deep taproot established.

Watering Requirements

During the first growing season, water your Milkweed twice a week to help the taproot dive deep into the soil. Once established, these plants are incredibly drought tolerant and rarely need supplemental water unless the leaves begin to wilt during a prolonged heatwave. Inconsistent watering during the first year can lead to stunted growth, but once the root system is mature, the plant becomes nearly self-sufficient.

Pruning Tips

Common Milkweed blooms on new wood, so you should leave the stalks standing through winter to provide habitat for beneficial insects. In early spring, cut the dead stems back to about two inches above the ground to make way for fresh new growth. This annual "reset" prevents the plant from looking messy and encourages a flush of vigorous, leafy stems that are perfect for hungry caterpillars.

Fertilizer Needs

Use a balanced, slow release fertilizer once in early spring as the new shoots emerge from the soil. Avoid using high nitrogen fertilizers late in the summer because this encourages soft, succulent growth that is highly attractive to aphids and may not harden off properly before the first frost. In most garden soils, a simple top-dressing of compost in the spring provides all the nutrients this native plant needs.

If you have a yen to help our amazing Monarch butterflies regain their population numbers...there is no better help than Common Milkweed (Ascelpias syriaca). Trust us, this isn't just another "weed".

Herbaceous Common Milkweed is absolutely critical to the healthy growth of these instantly recognizable black and orange butterflies. The eggs are laid on Common Milkweed plants to give caterpillars a ready food source.

This robust native plant acts as a clarion call for beneficial pollinators of all kinds, in fact. It creates showy colonies in naturalized plantings.

It's time to reimagine Common Milkweed as a valuable plant in the right landscape setting. A stand of these important native plants adds a showy, rough texture all season long.

The fragrant blooms are held in attractive spherical umbels composed of a hundred or more tiny true flowers. Intricate purple, pink and white blooms will be covered in butterflies and honey bees for several months each summer.

A strongly vertical main stem is softened with broad, thick leaves on either side. Light green on top, the underside is grayish-green with red veins.

Common Milkweed has been utilized to make fibrous cord, food, and even medicine through the years across the United States. But today, its value to Monarch butterflies makes it a staple for consideration.

The butterflies lay their eggs on the soft underside of these leaves, which contain natural cardiac glycosides or cardenolides. Nature's chemicals provide protection for the vulnerable caterpillars and make them distasteful to most predators.

Lack of habitat threatens the Monarch butterfly's migration paths. Tucking even a small planting dedicated to Common Milkweed in a sunny spot will really help boost their numbers.

Common Milkweed is native to North America and thrives in a wide array of conditions, including disturbed soil. It grows best in well-drained soil somewhere it can bask in the sun for hours.

Make a difference and leave a legacy by thoughtfully including native Common Milkweed. Order one or many more and turn some of your space into a beneficial Pollinator Garden!

How to Use Common Milkweed in the Landscape

On large lots, a generous swathe of native plantings create a magnificent feature in open, sunny areas. Mow wide walking paths through an exceptional prairie planting, where you'll appreciate the sight and fragrance of your Milkweed colonies dotted here and there.

Create a destination spot to enjoy picnics with family and friends. We are so proud to offer high-quality American wildflowers in our vast online catalog.

Even smaller gardens can help bring support for your local ecology. Although this species variety does grow vigorously, there is a way to use it on suburban lots.

Look for an area that receives lots of light each day to plan out your Butterfly Garden. Perhaps that is in your front yard or a forgotten side yard.

The key to using wildflowers in a "tame" environment is to pay attention to the finished edges. Invest in locally sourced quarry materials to edge your planned garden beds.

Once symmetrical planting beds are filled to bursting with vibrant flowering wildflowers, they become a dramatic study in contrasts. Install a formal frame around your wildly riotous blooming "living painting".

In urban areas, why not create an outdoor sign that explains the goals of your planting? Bolt a plasma-cut metal butterfly sculpture to a study column set in concrete for a long-lasting ornament that won't fly away.

Some funky neighborhoods are a little more free-form. There, add a wide curved bed that follows the lay of your land. Have fun recreating your local ecosystem in miniature and you'll spark plenty of conversation with your neighbors.

Don't forget to include cozy seating areas nearby. Keep binoculars in a weatherproof box, along with a special notebook to write down your daily sightings.

You can easily see why kids might get excited about this endeavor. Why not add a tall Tipi of annual runner beans nearby for a fun place for them to dream?

Victory Gardens and backyard orchards can realize a huge boost of productivity with Common Milkweed used nearby. Reclaim some space in your utility areas for these valuable host plants...such as behind the compost bins.

#ProPlantTips for Care

Give these native wild plants full sun so you can enjoy plenty of blooms and sturdy stems. Common Milkweed needs at least six hours of sunlight a day.

The soil type truly doesn't seem to matter to these exceptionally durable plants. In fact, this is an excellent choice to use on rough or disturbed ground in newly constructed areas.

Give a consistent schedule of water during the first season. Watch established plantings during extended drought and supplement with water as needed to protect your investments.

If you need to keep the colony in check, consider snipping the seed pods in the fall before they split open to release the fluffy seeds. They make wonderful dried arrangements and adorable wreaths.

In early spring, snip the dried stalks to an inch above ground level. Wait until spring, as the dried stalks provide winter shelter.

Yes, you may need to take up the mantle of educator by making this important choice. Become a proud ambassador for the beautiful Monarch Butterfly and order Common Milkweed from our native plant experts today!
