Polyanthus plants, sometimes known as primrose, are a spring plant that offers blooms in a rainbow of colors. There is a difference between a Polyanthus and a Primrose. A primrose has one flower on a stalk, but a polyanthus has many.
One of my favorite flowers: Columbine Genus: Aquilegia spp. Zones: Bloom time: May; then six weeks later. To prune: Cut the stems all the way back to the foliage. Good to know: After the second bloom, leave the blossoms on the plant to reseed.
