Hi Everyone,

I just dug this up from my brother's yard this evening and he has no idea what it is and neither do I. He says they planted it last spring and it has sprouted up all over his beds in various areas of his yard. It's pretty but it's purple and I have too much purple. But I do like it so much that I'll find a spot for it.

I'm sure you garden afficionados know what this is....can you clue me in? Ceejay.....your expertise is requested my dear!!!!!!

Thanks,
Kristi
