Nasturtium officinale

Wildflowers Dicots Eudicots Rosids Brassicales Brassicaceae Nasturtium

Nasturtium officinale flowersWatercress. Grows in streams. Common in the Ventura River. Small patches show up on various creek.

It is difficult to get a good feel for when it blooms since winter floods tend to scour it out of our creeks, but in the winter 2011-2012 we did not get a heavy enough rain, and it looks as though watercress starts blooming in late March and finishes in mid-December.

Formerly this was known as Rorippa nasturtium-aquaticum. Calflora claims it is indigenous to California, while Wikipedia implies it is only native to Europe and Asia.
