Solidago canadensis
A hardy perennial with pretty fluffy golden heads on 2 to 3-foot stems in late summer and autumn. Butterflies and bees, also Hoverflies love this flower and they eat pests like greenfly and blackfly, so a good companion plant in the organic garden. The plant quickly spreads to make a carefree patch, but it can be invasive so should not be planted near sensitive environmental areas where it may invade.
It can also be used to give yellow and brown dye from the leaves and the flowers. (see our books section for more about natural dyeing)
