Coreopsis grandiflora 'Domino'

This was the first coreopsis I ever grew. I have it in my current garden where it's been a star performer, continually blooming in an especially hot, windy area of an already hot, windy garden. It is one of the absolute favorites of small to medium bees/wasps/flies (which pollinate other plants too and in many cases, also have larvae that eat pests) and almost every time I walk by it (it's planted beside the house's stairs so that's frequently!) there is at least one on it.

In my previous garden it grew well for 3-4 years and then started to decline, but in my experience that is unfortunately typical of Coreopsis grandiflora cultivars.

This flower was the most stunning flower in my garden the first year I planted it. Very prolific flowering and additional blooms with deadheading. The only downside was that it was very short-lived, for me at least, and only lasted two years.

Flowers are yellow with dark brown centers. Has more of a mound-like habit than many other coreopsis varieties. Reaches a height of 15".
