Rough Goldenrod
In late summer the blooms appear along 18-inch arching stems held above the foliage to provide a stunning display of yellow flowers that resemble fireworks, hence the cultivar name. These blooms are very attractive to various butterflies and bees. It pairs nicely with the blues and lavenders of asters or Joe-pye weed. 'Fireworks' is not aggressive and will not try to take over your garden as it spreads slowly by rhizomes. Divide every three to four years or as needed. Cut the plant down in early spring before it starts growing again.
