Plant Milkweed, Save a Monarch

How Your Garden Can Help

heidi grasman |  july 28, 2026

Every summer, one of the most extraordinary journeys in the natural world plays out across North America. Monarch butterflies travel thousands of miles from their winter grounds in the mountains of central Mexico all the way to breeding sites across the United States and Canada, and back again. They navigate by the sun. They travel in generations, no single butterfly completing the full round trip. And they've been doing it, reliably, for thousands of years.

 

Until recently.

 

Monarch populations have declined by more than 80% in recent decades. Habitat loss, pesticide use, and climate change have all played a role. But one factor stands above the rest: the disappearance of milkweed from the American landscape. Milkweed isn't just a plant monarchs happen to like. It's the only plant monarch females will lay their eggs on, and the only food their caterpillars can eat. No milkweed, no monarchs. It's that simple.

 

The hopeful part? This is a problem home gardeners can genuinely help solve, one garden at a time.

An Extraordinary Migration and a Species in Trouble

To understand why milkweed matters so much, it helps to understand the monarch's life cycle. A female monarch doesn't just land on any flowering plant to lay her eggs. She searches specifically for milkweed and deposits her eggs on the leaves. When those eggs hatch, the tiny caterpillars feed exclusively on milkweed foliage. The plant's natural compounds actually accumulate in the caterpillar's body, making the adult butterfly toxic to most predators. It's a relationship millions of years in the making.

 

Milkweed was once abundant across North America, growing in fields, along roadsides, in meadows and disturbed ground wherever the monarch needed it. Over the past few decades, widespread herbicide use in agriculture, land development, and changes to how roadsides are managed have eliminated it from vast stretches of the monarch's migration route. The butterfly population has followed the milkweed down.

 

Planting milkweed in your garden doesn't just beautify your yard. It restores a piece of the habitat that monarchs need to complete their journey. 

What Is a Monarch Waystation? 

You may have heard the term "monarch waystation". It's exactly what it sounds like. A waystation is a garden planting that provides two things monarchs need: milkweed for breeding (eggs and caterpillars) and nectar-producing flowers for feeding adult butterflies as they travel. Think of it as a rest stop and a nursery rolled into one sunny garden bed.

 

The idea is powerful in its simplicity: if enough individual gardeners create small waystations, they collectively rebuild the connected network of habitat that monarchs depend on to migrate. Your garden doesn't need to be large. Even a few well-chosen plants make a genuine difference as one link in a much larger chain stretching from Mexico to Canada and back.

 

Monarch Watch, the leading monarch conservation organization, runs an official waystation certification program if you want to take the next step and register your garden as part of the formal network.

Choosing the Right Milkweed for Your Garden 

Not all milkweeds are created equal and the most important variable isn't color, it's soil moisture. The two main native milkweed groups have very different preferences, and planting the right one in the right spot is the difference between a thriving monarch habitat and a plant that quietly sulks for a season. Here's how to match the milkweed to your garden.

For Dry to Average Soil: Asclepias Tuberosa Types

Butterfly Weed (Asclepias tuberosa) is the classic with vivid orange flower clusters on a compact 24-inch plant, blooming from midsummer into fall. Hardy in zones 3–9, drought tolerant once established, and deer resistant. If you're only going to plant one milkweed, start here.

 

'Hello Yellow' is a cheerful tuberosa cultivar with the same tough, adaptable nature as the straight species but in a warm golden yellow. Planted together, orange Butterfly Weed and 'Hello Yellow' create a layered, complementary display that runs from early summer through fall — which is exactly the combination in our Monarch Waystation Bundle.

 

Showy Milkweed (Asclepias speciosa) is the bolder option, reaching 2–4 feet with large leaves and soft pink blooms in midsummer. Hardy in zones 3–8, it's a natural fit for wilder garden styles, prairie plantings, or anyone who wants a more dramatic presence in the border. 

For Average to Moist Soil: Asclepias Incarnata Types

The swamp milkweed family handles moisture better than their tuberosa cousins, making them the right choice for spots that stay consistently moist, rain gardens, or areas near water features. They're equally valuable as monarch host plants and bring their own considerable charm.

'Soulmate' is the most compact of the group at 2–3 feet, with deep rose-pink blooms and a sweet vanilla fragrance that drifts through the garden on warm summer days. Hardy in zones 3–9 and a prolific bloomer, it's one of the best choices for smaller spaces.

 

'Cinderella' delivers rose-pink, vanilla-scented flowers for up to three months straight, an unusually long bloom window that keeps monarchs coming back through the season. Hardy in zones 3–8. One planting tip worth noting, 'Cinderella' puts down a deep tap root and doesn't like to be moved once established, so choose its spot thoughtfully.

 

'Ice Ballet' is the white-flowered standout of the collection with pure, fragrant white clusters on tall 3–5 foot stems that make a striking backdrop for the pinks and oranges nearby. Hardy in zones 3–9, it handles wet conditions especially well and earns its place in rain gardens and moist borders where other milkweeds would struggle.

 

Swamp Milkweed (Asclepias incarnata) is the straight species, with soft pink blooms, 2–4 feet tall, zones 3–9, and a natural self-seeder that fills in and naturalizes beautifully over time. If you want a milkweed planting that grows and spreads on its own with minimal input, this is your plant. 

A Note on Tropical Milkweed 

Garden Crossings also carries annual tropical milkweed varieties which are beautiful, long-blooming, and genuinely attractive to monarchs. One thing worth knowing: in zones 8 and warmer where they don't die back in winter, leaving tropical milkweed standing year-round can sometimes disrupt monarch migration timing. In zones 3–7 where frost kills them back naturally each fall, this concern doesn't apply, grow them freely as the annuals they are.

The Monarch Waystation Bundle: The Easiest Way to Start 

If you want to help monarchs this season without spending time planning a planting, the Monarch Waystation Bundle makes it simple. It includes six plants, three Butterfly Weed (orange) and three 'Hello Yellow', two of the most reliable native milkweed varieties, paired together to give monarchs a host plant for their caterpillars and season-long color from early summer through fall.

 

Both varieties are hardy in zones 3–9, deer resistant, drought tolerant once established, and thrive in full sun with well-drained soil. Everything you need to start a functioning monarch waystation arrives in one order. Plant in full sun, water consistently through the first season while roots establish, and then let the monarchs do the rest.

Every Plant Counts 

The monarch's situation is serious. But it's not hopeless and that's what makes milkweed gardening feel different from most conservation efforts. This is something you can do today, in your own yard, that has a direct and measurable impact on one of nature's most remarkable creatures.

 

Migration season is underway right now. Monarchs are moving through, looking for exactly the milkweed that your garden can provide. Plant a waystation this season, and your garden becomes part of the solution.
