Don’t go grabbing a bottle of wine just yet! These wine cups, Callirhoe involucrata, belong to the Malvaceae, or the mallow family. It is native to many of the plains states, including Missouri, New Mexico, North Dakota, Oklahoma, Texas, Utah, and Wyoming. This is a drought tolerant plant that does well especially during hot summers without much rain and in the sun. It will also tolerate some partial shade. Due to the overall tolerance of the plant, it is recommended that one does not try to transplant as it will give resistance. The resistance comes from the long taproot of the plant. The plant prefers well-drained sandy or loamy soils but will tolerate clay. It can rot if the soil is poorly drained.
Wine cups is a purple flowering perennial that is also known as the purple poppy mallow. Its low and mat-forming habit makes it a great groundcover plant that does well in Zones 4-8. Eventually, this plant will spread to about 3 feet wide and about 6 to 9 inches tall. It can easily be used for naturalized areas but can also easily fit in amongst formal areas. Palmately arranged leaves and magenta flowers help characterize the plant. Each magenta colored flower has five petals in an upward cup formation and can be found from mid-spring through fall. Each flower will close in the evening and open again in the morning. Once a flower has been pollinated, it will remain closed.
This plant is great sprawling over rock walls, in rock gardens, and elsewhere. Plant individual plants only several inches apart so that they will mat together. One can plant with a variety of plants depending on the purpose of the garden. Some suggested plants to plant with the Wine Cups are Veronica, Stachys (lamb’s ears), Hemerocallis (daylillies), and Aquilegia (columbine).
