Two Leopard's Bane were planted last fall and survived the winter . They are in sun/part sun. The soil has been amended with lots of organic matter. The flowers were cheery in the spring. Now , mid-July their leaves are browning. One plant is much worse than the other. These plants did get a little crowded with Yarrow growing beside them. I have cut back the Yarrow to fully expose the Leopard's Bane, but the plants are still declining. We have had a very wet spring/early summer.
Is this decline part of a normal cycle ?
