Tumbling Mustard

A Tumbling Mustard plant looks like a loosely branched bush, about 3 or 4 feet tall. When the seeds are ripe and the plant is dry, it can often break off near the ground and go tumbling along with the wind, scattering its seeds. The flowers follow the typical Mustard pattern -- all have four petals, four sepals, and six stamens (4 tall and 2 shorter ones).
