These grow extensively in large shaded grassy areas here in Houston. I have transplanted some to pots and have had great success keeping them; however, I must say they are extremely succeptible to spider mites and aphids. More so than almost any other plant I have tried to grow here my violets, and particularly these, are constantly overcome with black aphid-like insects and colonies of spider mites. While they grow well in pots under good condition, keeping them healthy in the abyssmal ecological black hole of much of Houston's urban area can be quite a chore.

I discovered the Missouri violet on April 3, 2004 growing under a peach tree in the yard. Then l transplanted it to the garden for later seed collection, but l never found seeds. Apparently the purple flowers are male flowers. The violet/pansy family Violaceae is in the Violales order along with the Cucurbitaceae squash/melon family. Those all have male and female flowers too, so that makes sense.
