5 Milkweeds to Plant in Your Butterfly Garden

Discover five native milkweeds to plant in your butterfly garden for stunning blooms that support monarch butterflies throughout their life cycle.

It’s not a weed, and it doesn’t produce milk, but the humble milkweed is one of the most important plants you can have in your garden. This tough native plant grows just as well in North American wetlands as it does in fields and prairies. It is a host plant for monarch caterpillars and critical to growing the monarch butterfly population. While most butterfly species can feed on a variety of host plants, monarch caterpillars can only survive on a diet of milkweed. 

Here are five milkweeds to add to your butterfly garden that will support monarch butterflies throughout their life cycle.

1. Swamp milkweed (Asclepias incarnata)

Swamp milkweed features vibrant pink blooms that attract pollinators, including monarch butterflies and native bees. As the name suggests, it thrives in wetter conditions and clay or mucky soil, making it ideal for rain gardens and wetlands. This milkweed blooms from June-October and grows up to 4 feet tall. 


2. Whorled milkweed (Asclepias verticillata)

Whorled milkweed is a resilient and versatile native plant, perfect for dry, sunny, and partly shaded areas. Its pale green-white hue and thin, whorled leaves create a delicate beauty in your garden. From May through September, this milkweed produces tiny, fragrant blooms that provide nectar for a variety of butterflies and bees, making it an essential addition to any pollinator-friendly garden. It grows between 1-3 feet tall and tolerates clay, sand, and rocky soils that may be challenging for other plants to thrive in.


3. Orange butterfly milkweed (Asclepias tuberosa)

Orange butterfly milkweed, also known as orange milkweed or butterfly weed, is a must-have for any butterfly enthusiast looking to support monarchs and other critical wildlife species. This stunning native plant features clusters of vibrant yellow to bright orange flowers, providing a splash of color that attracts monarchs, queen butterflies, and a host of other pollinators. Butterfly weed grows between 1 and 3 feet tall and blooms from June through September. With its compact, shrub-like structure, it's perfect for urban or suburban yards and even large containers.


4. Snowy milkweed (Asclepias perennis)

Snowy milkweed, aka aquatic milkweed, is abundant with creamy white flowers tinged with soft pink, that sit in clusters on stalks with short narrow leaves. The flowers bloom from May through September. This milkweed grows 1-3 feet tall and is ideal for rain gardens and partly-shaded, moist environments in the South Eastern United States (Florida, Georgia, South Carolina, etc.).


5. Showy milkweed (Asclepias speciosa)

Showy milkweed is more manageable than common milkweed, with fragrant blooms, large oval shaped leaves and spiky pink flowers at the stems. It grows anywhere from 2 to 4 feet tall and blooms June though August, thriving in the sunny, dry climates of the Western U.S. (Colorado and New Mexico). 

 

Are there other native species of milkweed? 

Yes! There are dozens of milkweed plants that are native to North America. Common milkweed (Asclepias syriaca) has large balls of pink or purplish flowers that have an attractive odor. The flowers bloom from June to August and it usually grows 3-5 feet, but can sometimes reach 8 feet! 

There's also purple milkweed (Asclepias purpurascens) with rich magenta-purple flowers that bloom from May to July and antelope-horns milkweed (Asclepias asperula), also known as spider milkweed, with green seed pods that curve to resemble antelope horns. This species of milkweed has pale, greenish-yellow flowers, tinged maroon that bloom from March to October.

Is there a non-native milkweed plant?

Yes, tropical milkweed (Asclepias curassavica) is a non-native milkweed in North America that can become invasive. Also known as mexican butterfly weed, it is native to the American tropics. It doesn't go dormant like native milkweed and it's known to become contaminated by the Ophryocystis elektroscirrha parasite that can kill monarch and queen butterflies. It's commonly sold in garden centers and big box stores so make sure you avoid this one!
