Q. Who is Mr. Smarty Plants?

A: There are those who suspect Wildflower Center volunteers are the culpable and capable culprits. Yet, others think staff members play some, albeit small, role. You can torture us with your plant questions, but we will never reveal the Green Guru's secret identity.

Title: Best Asclepias for Kansas City
Answered by: Anne Van Nest

QUESTION:

I have a question about the Asclepias. I live in the Midwest, in Kansas City with hardiness zone 5b or 6. I want to know which of these plants would be good for me in a cultivated garden. It's not too tidy but we have hot summers so some plants go wild. I have a lot of monarchs feeding here on all my other plants but I read that Asclepias is better for them. I wondered if you could suggest a few that the butterflies particularly like? Annuals or perennials, either will be wonderful. I would just like to know in your opinion which produces the best amount of flowers without being too promiscuous.

ANSWER:

There is a wonderful list of Asclepias (milkweed) that are native to the Midwest for you to consider on the Lady Bird Johnson Wildlfower Center Native Plant Database webpage. Just do a search for Asclepias and Kansas. As you know, milkweeds are the primary food source for Monarch and Queen butterfly caterpillars and good nectar sources for the adults.

Asclepias amplexicaulis (clasping milkweed)

Asclepias arenaria (sand milkweed)

Asclepias asperula (spider milkweed)

Asclepias engelmanniana (Engelmann's milkweed)

Asclepias hirtella (green milkweed)

Asclepias incarnata (swamp milkweed)

With its showy flower clusters that attract butterflies and hummingbirds, swamp milkweed is underutilized in gardens. In moist soils or in a pond, it will thrive. The interesting seed pods look like other milkweeds.  Good for wetland gardens and habitat.

Asclepias latifolia (broadleaf milkweed)

Asclepias purpurascens (purple milkweed)

For more information about which Milkweed is best for Monarchs, take a look at the MonarchWatch.org website. For their Bring Back the Monarchs campaign they have a profile of most of the Asclepias listed above.
