2018 Update: Echinacea hybrids– exPt 6

In 2018, we searched for 30 of the original 66 Echinacea hybrid plants. We found 29 Echinacea hybrids… which shows incredibly low mortality!  This means that 40% of the original cohort is still alive, with the survival rate this winter of more than 96%! Of the surviving plants, the average leaf count was 2.2 leaves, the longest basal leaf was 14.75cm. These plants are considerably smaller than their exPt9 counterparts, despite being several years older.

This big bluestem made finding these tiny plants pretty hard!

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. A chapter of his dissertation, which he defended in December, reports on the fitness of hybrids compared to plants of either species.
