The foliage still looks pretty during winter and even looks more blue. 'Jackman's Blue' can be best propagated from tip cuttings taken in autumn. If sown, Rue can get untamed wild.
Don't plant it near to your path ways or where it is easy to touch.
Some people are allergic to rue and get a skin rash from handling the plant. Especially on hot days, just brushing against rue can cause water blisters and blotchy skin, much like poison ivy. For some people, ingestion causes increased photosensitivity and can lead to severe sunburn. Ingesting large amounts of rue can cause violent stomach pain, vomiting, and convulsions. Pregnant women should never ingest rue.
