Common Milkweed Common milkweed, a tall summer bloomer in 39 states, thrives in open spaces with full sun, but small gardeners should consider less aggressive types. Why we love it: Globes of pink-purple stars shine on 3- to 5-foot tall plants from June through August.

Swamp Milkweed Striking magenta and white flower balls bloom summer through fall and prefer shade and moist soil. Why we love it: Growing in 43 states, this adaptable 2- to 5-foot-tall plant is readily available. Also, swamp milkweed is not a romper.

Butterfly Weed Butterfly weed, a vibrant plant found in 41 states, blooms in warm golds and oranges, with its flat-topped clusters displaying their beauty from May to September. Why we love it: Well-behaved and compact at 1 to 2 feet tall, it’s easy to fit into any sunny, well-drained garden..

Whorled Milkweed This 2-foot by 2-foot prairie plant, with fine-textured needle-like leaves and pale cream summer flowers, prefers dry sunny conditions. Why we love it: One of the first types of milkweed to emerge, it sustains monarch butterflies who arrive early.

Purple Milkweed The plant, averaging 2 to 3 feet tall and wide, thrives in consistent watering, loamy soil, and partial sun, though it may take time to establish. Why we love it: That look-at-me rosy magenta is distinct among milkweeds and will be the jewel that sets off the rest of your collection.

Sullivant’s Milkweed/Prairie Milkweed This milkweed, resembling a pink columbine bouquet, thrives in full sun and moist soil, growing 2 to 3 feet tall and 1 foot wide. Why we love it: It spreads more slowly than common milkweed but is just as lovely.

Showy Milkweed The showy milkweed, reaching up to 3 feet tall, thrives in dry, arid soils with good drainage, making it an excellent choice for western and southwestern U.S. gardeners. Why we love it: The star-shaped blooms are stunning and it is very drought tolerant.

Antelope Horn Milkweed/Spider Milkweed This Southwest native stunner, similar to A. viridis, mimics horns' seed heads and grows up to 2 feet tall, preferring sun and sandy or clay soil. Why we love it: The floral show lasts from March to October, getting better each year.

Short Green Milkweed A. viridiflora, a type of milkweed, has palest green flowers resembling stylized alliums and thrives in sandy or gravelly soil in hot, dry conditions.

Poke Milkweed This plant features drooping clusters of white or purple flowers that float on 3- to 5-foot-tall plants from May to August. Why we love it: Poke milkweed is one of the most shade-tolerant types of milkweed, so give it a try if your gardens are more shady than sunny.
