These pretty prairie plants are called ‘Winecups’ since they do resemble a cup of grape wine but their name is purple poppymallow. The USDA ‘Plants Database‘ this species is native to the following states: AR, AZ, CO, FL, IA, IL, IN, KS, LA, MI, MN, MO, ND, NE, NM, OK, OR, PA, TX, VA, WY.
I have seen them sprawling around the dry prairie and have wanted to plant some in my yard for some time. I think they are gorgeous and I like their habit of spreading. This spring I purchased two small plants and put them in the drier section of my yard as they are drought resistant. I was delighted when they not only started spreading but bloomed after being transplanted just 5 weeks before.
Some of the ‘cups’ are such a deep purple while others are more a lilac color. The useful online reference Wildflowers.org describes them as follows: “An attractive, spreading, drought-tolerant perennial, Winecup is susceptible to a rust during wet seasons in the Great Plains.”
These Winecups produce nectar and attract native bees. That is an outstanding feature as bees are in trouble and they are very important to our food supply.
Purple poppymallow plants (aka Winecups) also attract butterflies. They are the larval host for the Gray Hairstreak butterfly which is the most widespread ‘hairstreak’ butterfly in North America–and they are sure pretty and petite (their wing span is only around an inch to just under and inch and a half).
