Whorled Milkweed is a North American native meadow plant and the primary host plant for the Monarch butterfly. Also known as Asclepias verticillata, this plant can be found in most of the Central and Southwestern United States. In addition to Monarch butterflies, many other beneficial insects, such as native bees and wasps, are attracted to this milkweed. It is a plant that adapts to many conditions and soil types and is the latest blooming of all the milkweeds, blooming from late July to October.
The creamy white flowers of Whorled Milkweed are very fragrant and blend well in meadow plantings or naturalized plantings in a garden. The loose flowering heads and leggy shape make this plant blend in well with a cottage garden or pollinator bed in a kitchen garden. Whorled Milkweed is one of the more toxic milkweeds for livestock and should not be planted near open grazing areas.
Whorled Milkweed Care
Whorled Milkweed grows well in full sun to part sun and will tolerate a wide range of soils. The soil should be well drained but moist. Milkweed does not require high nutrition to grow well and will self-seed heavily in fertile soils. After this native plant is established, it is drought tolerant and will require little supplemental irrigation. Milkweed spreads mainly from underground rhizomes that extend from the main plant. Vigorous spreading can be kept in check by dividing and replanting it every 2-3 years.
The spent flower heads can be deadheaded to keep self-seeding under control. The tiny seed is wind dispersed and can spread far from the mother plant. Clear away the previous season's top growth in early summer. Allowing it to remain in place over the winter will protect any Monarch eggs laid the previous season and shelter pupating larvae.
Whorled Milkweed Spacing
Whorled Milkweed can be spaced 12 inches apart. This allows for good coverage of the ground and weed suppression while maintaining adequate air circulation.

Plant Shipping
Below are some factors we consider when determining when to ship the plants depending on the timing of the order.
Winter to Early Spring
We ship only when it's warm enough to plant in your growing zone.
Sometimes plants aren't completely ready to sell and ship in early spring. We will wait until the plants are ready before shipping so you don't get a subpar product.
For Southern plants we will be able to ship much earlier than plants coming from our northern nursery.
Summer
If there is extreme heat we may delay shipping for a week or several weeks.
We review what areas the plants are traveling through as well as your location.
Fall into Winter
We’ll ship plants out all the way up to the end of the fall planting season!
Winter
Get your order in early to reserve your plants for Spring planting!
Once your plant is shipped you’ll receive an automated email with tracking information.
