I have a love/hate relationship with this plant and am now in the process of trying to eliminate it, at least from the "tame" flower beds.

I too got this originally from Gardens North. The first few years were fabulous - sure, it's a bit reminiscent of a huge mustard in appearance but the flowers are showy, quite long lasting, sweetly fragrant and hugely enjoyed by our honeybees.

But ... it self seeds profusely, to the point of weediness, and the roots are tough and of the "resprout from any snippet left in the soil" persuasion.

I suggest that if you grow this you should be vigilant about deadheading - do not let it seed into your flowerbeds! One for the wild garden, perhaps?

The perennial Sisymbrium luteum is a native of Japan, Korea and Manchuria. It was formerly known as Hesperis lutea. I obtained seeds for it from Gardens North Seeds a number of years ago and have enjoyed the airy yellow blooms each year since. It grows about 4.5 ft tall for me and has never reseeded. A very easy and trouble free plant to grow that adds color to my yard at a time of the year when not a lot else is blooming.
