The pollination biology of hybrids of Echinacea simulata and Echinacea paradoxa.

On a glade at Shaw Nature Reserve, MO two species of Echinacea (Echinacea simulata and Echinacea paradoxa) co-bloom and are hybridizing. The F1 hybrids have a yellow- cream color, and the F2 hybrids, which are orange in color, result from a backcross of either parent. Pollinator observations were conducted to determine the pollination system of both species and hybrids. Current pollination data was compared with past data (2013 and 2014).  Current seed data was compared with past data (2013) to get average seed sets. The main pollinator in 2013 and 2014 was Bombus spp., but shifted in 2017 to Apis mellifera. The main vector for hybridization of the two species also shifted from Bombus spp. to butterfly’s which aren’t as effective pollinators. This change in main pollinator did not impact the reproductive success of either Echinacea species or the hybrids
