Common Rue | These plants were grown from seed in the nursery at Yew Dell and are supposed to be the variegated form. A few of the leaves had variegation early on but they have lost all of it now. A great pollinator plant and a host plant for Swallowtail butterflies! The light blue/green foliage adds some interesting contrast to the garden although caution should be used when handling this plant because of allergic reactions. Gardening can be treacherous sometimes!
