Oligoneuron riddellii (Riddell’s Goldenrod) [20 Seeds]


Germination Information: I recommend these seeds for experienced seed-starters only, because they may require some patience. The easiest approach is to purchase and surface-sow (do not cover) the seeds in fall to late winter, setting them outdoors in a spot protected from mice so they can get a chilling period and then germinate when conditions are right in spring.

If you sow after February, set the pot in a plastic bag in your refrigerator for about two months before moving it to a warm, bright place for germination. (Remove the bag if the pot will be exposed to any direct sun.)

It is possible that these seeds could germinate if you sow them in warm, moist, bright conditions. But if you try that and no seedlings appear within 2 to 3 weeks, then try the refrigerator-chilling approach above before moving them back to warmth and light.

Note that this information will not appear on the seed packet you receive.

As a group, goldenrods are hard to beat for bright blooms, late-season color, and pollinator-feeding flowers. I grow several kinds here at Hayefield, and I’m always on the lookout for different species to try. Riddell’s goldenrod (Oligoneuron riddellii, formerly Solidago riddellii) was a new one for me last year, and it’s definitely a keeper. The flat-topped to somewhat domed bloom clusters and the plant’s clump-forming, compact habit (to around 3 feet tall) make it stand out from other species. It’s pretty in the garden and great as a cut flower too. This Midwest native thrives in full sun and moist to wet conditions. Perennial; Zones 3 or 4 to 7 or 8.

Seed collected in late October 2021. At least 20 seeds.
