Lazy S's farm says this, "AND not only is it deer resistant but planted amongst your other perennials and allowed to naturalize, WILL KEEP DEER OUT OF YOUR GARDEN. They won't go anywhere near this plant!"
In Sequim that isn't the case, but the plant is still worth the space. I have a wester flisk growing with heather and the deer will still investigate any crocus coming up and prune the weeping cherry.
I love to garden in the great northwest. I have a growing interest in TBI for their beauty, foliage texture in the border and our resident deer mostly ignore them:)
