Offsets are then planted in a rich potting medium until they leaf out. Often, leaves on offsets are cut off, but that is not necessary. New leaves will appear once the pups establish a root system. I have seen a growing along FM 624. They have striking dark purple flowers that look a lot like winecup flowers, but they grow up to three feet tall.
Wine cups are only a few inches tall.
You were right in thinking the blossoms looked like a wine cup. They grow in sandy loam or caliche soils in pastures and woods. I must agree that these upright winecups have magnificent flowers. If you haven't taken time out to enjoy these or other wildflowers, I urge you to do so. They have really come out in all of their glory since we had some rain last month.
