Rudbeckia triloba ‘Prairie Glow’ (Brown-Eyed Susan) [20 Seeds]

(2 customer reviews)


Germination Information: I recommend these seeds for experienced seed-starters only, because they may require some patience and experimentation. The easiest approach is to surface-sow (do not cover) the seeds in fall to mid-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 January, give the pot an artificial chilling period of about 2 months.

It is possible that these seeds could germinate (though perhaps at a lower than optimal percentage) if you sow them in warm, moist, bright conditions. But if you try that and no seedlings appear within 3 weeks or so, then try the artificial-chilling approach above before moving them back to warmth and light.

With their bold, bright, daisy-form flowers, rudbeckias are so wonderful for summer color. ‘Prairie Glow’, a strain of our native brown-eyed Susan (Rudbeckia triloba), offers something different than the usual solid golden yellow, with varying amounts of red to orange in the dark-centered blooms. The bushy plants are in the range of 3 to 5 feet tall and flower from midsummer into fall. ‘Prairie Glow’ can bloom the same year you start it from seed, or it can act like a biennial, with flowers the second year from a summer sowing. The plants may even last an additional year or two after that. If you leave the dried seedheads on the plant, it is likely to self-sow from the seeds the birds miss, so you can have an essentially perennial patch from just one sowing. Full sun to light shade. Annual, biennial, or even a short-lived perennial; Zones 4 to 8.

Collected in mid to late September 2022. At least 20 seeds.

    Germination was all over the place with these, just as noted on the website. I have several strongly-growing plants, some that are further behind, and some pots where nothing has happened yet but I’m sure it will. As Nan notes, it seems that the key to these is to try several different methods!
