This tiny mystery has been blooming for almost a month, I kept forgetting to get a photo to post. About 2 years ago I wedged a plant in a clay pot in the crotch of this crape myrtle. At some point a squirrel (I assume) dislodged it and it fell down and got lodged where I could not reach it. The pot was broken and I was able to retrieve a few shards but could not get to the plant. It has been hiding in there with no food, only occasional rain water and still lives on. I have no idea what it is, the flower is only about 1.5".
