Neutral melody On Feb 14, 2005, melody from Benton, KY (Zone 7a) wrote:

Triangular or arrowhead-shaped leaves with many teeth or jagged edges on several leafy stems topped by yellow flower heads in a branched flattish cluster.

As indicated by the common and species names, the triangular leaves are distinctive.

These cheerful blooms carpet the high mountain stream edges from Alaska to New Mexico and Southern California. They can be somewhat invasive under prime conditions of full sun and consistent moisture. I have not attempted to grow these, since they require cooler summer temps than I have at home.
