The plant was introduced to the US early and has been traditionally used for greens and medicinally. However, recent studies are indicating that consumption of Yellow Rocket could damage the kidneys.

I have not personally grown this plant, but several older people visited the nursery I worked at asking to pick this from the fields. They used it as a pot herb (cooked greens.) They called it "creases." It grows as a weed in the nursery fields, but I don't believe it was considered invasive.

Negative Equilibrium On Dec 4, 2004, Equilibrium wrote:

"Problem Child" introduced plant in my region. Not native to North America. Very weedy. I think it was originally used to treat wounds. Rather an early blooming species and I am relatively sure I saw it poking up with crocus one year. This makes it easier to spot and pull out of the ground if you want it gone! Most lawn care professionals routinely use chemicals to eradicate this around me.

I have had this plant growing up a wall for several years now and this year it finally bloomed. The foliage is outstanding and the blooms are pretty. I cannot say it has been invasive.It does take a few years to settle in and bloom.
