2017 Update: Echinacea hybrids– exPt 6

In 2017,  we searched for 56 of the original 66 Echinacea hybrid plants. We found 28 Echinacea hybrids, and 2 of the Echinacea hybrids we found just had dead leaves from this year.  This means that 42% of the original cohort is still alive, with the survival rate this winter of 78%. Of the surviving plants, the highest leaf count was 5 leaves, the longest basal leaf was 35cm, and only one plant had more than one basal rosette.

Most plants we measured in exPt6 looked like this.

This plot was originally developed for Josh Drizin’s experiment with exotic grasses, but 66 hybrids of Echinacea angustifolia and Echinacea pallida were also planted in 2012. In 2011, Gretel and Nicholas Goldsmith performed reciprocal crosses between 5 non-native pallida plants found at Hegg Lake and 31 angustifolia plants in P1. These plants have been revisited each summer since then.

Year started: Crossing in 2011, planting in 2012

Location: Experimental Plot 6, on Tower Road

Overlaps with: Echinacea hybrids — ex Pt 7, Echinacea hybrids — ex Pt 9

Data collected: Status, rosette count, longest leaf measurement, and number of leaves for each plant. Exported to CGData.

Products: Nicholas Goldsmith wrote a summary of the crosses he conducted in 2011.
