A bit invasive but a nice strong plant. The purple leaved forms are excellent color contrast at that height , about 3 foot. I raise the purple ones at the base of a garden wall so I can just mow along infront of them to keep them in bounds.
Since this appears to be Loosestrife can someone tell me how to control the growth pattern. Each yr (3) it growns from the center and has beautiful yellow flowers. It's almost like the flowers weigh down the limbs and it spreads or lays back, leaving the center empty. I could almost sit a flower pot in the center - which would be really beautiful. But this mean it needs trimmed or divided? If so, when? I would love to share this plant with anyone who wants to try it - just for postage.
Thanks for any help you can give.
