Faits intéressants

Riddell's Goldenrod was originally seen in open prairie-type habitat. In a home garden, it would thrive in an area with reliable moisture. As the flat-topped clusters of bright yellow flowers blossom, the leaves may wither away resulting in naked stems. Plants grown from seed may only flower in the second or third year. As with all goldenrods it is a pollinator magnet and an important fall source of nectar and pollen.
