Gardeners' Notes:

Positive coriaceous On Jul 1, 2013, coriaceous from ROSLINDALE, MA wrote:

The flower color is a beautiful soft apricot/salmon that lightens a little as the flower ages. This originated as a naturally occurring branch sport of Coreopsis 'Creme Brulee', discovered at Sunny Border nursery.

This is my second season with it, and though healthy, my clump seems smaller than it was last year. I suspect that, like 'Moonbeam', it needs frequent spring division to maintain vigor.
