2017 Update: Echinacea hybrids — exPt 7

This summer, we measured hybrid Echinacea plants in experimental plot 7 at Hegg Lake. 159 of the original 294 planted seedlings (54%) were found this year. We searched 243 of the 294 positions where plants were originally planted (the other 51 positions were not searched because plants have not been found for at least three years in a row). The table below shows the fate of plants in 2017 summarized by cross-type — the first name in the cross type is the maternal species, and the second name is the paternal species (e.g., ‘ang x pal’ is angustifolia mother and pallida father).
