I have two of Jacob Cline monarda and BOLTONIA AsteroidesSnowbank each. Since Boltonia needs to support and grows tall, I was thinking of pairing these two together on each end of my sunny perennial garden on a slope (anchor plants on the background).
IS this a wise idea? I understand Jacob needs support or droops all over. I was hoping by planting these front and back, I oculd get some support. Any advice?
