Pollinator Variety — Black-eyed Susan, Coneflower
Rudbeckia hirta L.
The concept of a 'pollinator variety' is not applicable to Rudbeckia hirta, as this species is self-fertile and does not require specific partners for seed set.
In the reference 3 varieties crop Black-eyed Susan, where this is mentioned in the description.
Rudbeckia hirta is an insect-pollinated plant that does not require the selection of pollinator varieties to ensure fertility. The reproductive biology of the species allows it to successfully set seeds both through self-pollination and with the assistance of insect pollinators attracted by the inflorescences.
Unlike fruit crops characterized by genetic self-incompatibility, which necessitates planting partners for cross-pollination, Rudbeckia hirta possesses sufficient self-fertility. Providing conditions for natural pollinators to work may contribute to increased seed productivity, but it is not a mandatory agrotechnical requirement.
