I know there are gardeners who see perennial coreopsis more as workhorses of the summer garden than plants with character and style but perhaps ‘Solanna Golden Sphere’ (left, click to enlarge) will spark some affection as well as admiration for being dependable and tough.
Developed in Israel, and propagated by division rather than seed so plants are always of a reliably high quality, the dark green foliage makes a neat mound. The bright, sunny yellow flowers open from May to October, each is fully double, with a slightly darker centre. Held one per stem, they are good for cutting and last well in water.
It’s worth noting that this is a plant that rewards gardeners who nip off the fading flowers with secateurs or the kitchen scissors as this encourages more buds to develop. Plants should still flower right through until autumn without dead heading but they will look more attractive and less messy – and there will be more flowers open at any given time – if the dead blooms are snipped of at the base of their stems.
This is a very hardy perennial which can be planted in a container for its first summer then moved into the border before winter, or can be planted direct into any reasonable soil in a sunny place.
