Fleur569, how poetic! You must be a poet at heart!? The clover shape is obvious now that you've said it; I was thinking tiny hearts, which is fairly close. I have only seen this plant in bloom once because we think it is actually my neighbors but borders our yards in an area that I rarely visit. The reason we are not sure it belongs to the neighbors is that there are no fences in our neighborhood which makes it hard to know where one property ends and another begins!
