Susan, after I did this post, I was thinking about kicking myself for posting it here. I guess this is a perennial, not a shrub. Where this one is planted is fine, for we space out our plants pretty well, and I don't think this little one will be taken over by anything. If it is, we will move it. I hate it when I see a picture of a plant in bloom and then if I get it, the flower is not the same color as in the picture--bummer!!!
