Oligoneuron riddellii (Solidago riddellii)
Soil: Hydric (Wet) – Mesic (Medium)
Sun: Full Sun
Height: 6 inches – 3 feet
Bloom Color: Yellow
Bloom Season: July – October
Suggested Uses: Riddell’s Goldenrod is great for moist soils including shorelines, rain gardens and wetland restorations. Often found growing in moist prairies and calcareous fens. It is attractive to butterflies and is also a beautiful fresh-cut flower! Goldenrods are not wind-pollinated and therefore do not cause standard hay fever or allergies.
Native Range: Native to the Midwest. Native throughout Minnesota except for the Northeast corner.
Pollinators: Many types of bees, including the federally endangered Rusty Patched Bumble Bee (Bombus affinis). An important source of nectar for adult monarch butterflies.
Flowers: Flowers develop in large, bright yellow clusters. Each flower is less than 1/2″ tall and has rounded bracts. Flower clusters often have relatively flat tops, similar to Stiff Golden rod (Oligoneuron rigidum), but different than Solidago species which rise to a point (plume-like).
Leaves: Leaves are narrow (narrower than those of O. rigidum). No serrations. Leaves often feel a bit leathery.
