Rue was one of the herbs planted in the first herb garden on the south side in 1992. It did really well there. For some reason I have no photos of it, just where it should be but you can’t see it. It was a pretty and robust plant early on so not sure why there are no photos.
I had noticed when I weeded that south garden a day or so later I would have dark brown splotches on my hands for a while. It took a few years to figure out what I was reacting to: the rue.
Sometime between 1999 and 2003 it was winter killed. It had been having a hard time with winter kill for a few years but always managed to come back. But this time it didn’t and I didn’t replace it due to the skin irritation.
Ruta graveolens L. aka garden rue, common rue, German rue, herb of grace, countryman’s treacle, is a hardy, evergreen perennial shrub from which you can use the leaves. It grows 2’ – 3’ high and can be found in pastures, roadsides, and abandoned lots. Zones 4 – 9.
