Rue (Ruta graveolens) is a charming perennial with aromatic, fern-like leaves and clusters of yellow flowers. Evergreen foliage takes on blue-green hues and releases a sweet and spicy fragrance when touched. Though it blooms with small yellow flowers in early summer, Rue is valued for its foliage. It serves as a host plant for swallowtail butterflies, including the black swallowtail, giant swallowtail, and anise swallowtail. You can find adult butterflies laying eggs on the leaves, then enjoy watching the caterpillars grow through the season. It may not be as showy as other pollinator plants, but it's just as important to include it in your garden!

We planted one plant and got two swallowtail caterpillars very soon. Fun to watch them grow!!
It’s healthy and happy!
I am between zone 4-5b and we planted the rue in full sun in a very stable mature bed. It started out with a few yellowing leaves and it has not settled in yet. It has been a month and it still looks like it did when we planted it. There has been no growth or dying off, it is exactly the same size it was when it came out of the box. We buy a lot of plants on line and GreatGardenPlants has a very good track record with us. Their shipping and packing is excellent.
We have not given up hope and we want to give the rue it a few more weeks. It looks fine, but it hasn't "taken" to the earth in any noticeable way. One of nature's little mysteries.
