2016 Update: Echinacea hybrids–exPt 6

Echinacea Pallida at Hegg Lake

Echinacea Pallida at Hegg Lake

Although originally used as part of Josh Drizin’s experiment with exotic grasses, this plot also has hybrids of Echinacea angustifolia and Echinacea pallida. Gretel and Nicholas Goldsmith performed reciprocal crosses between 5 non-native pallida plants found at Hegg Lake and 31 angustifolia plants in P1 and planted 66 seedlings between grasses in 2012. These plants have been revisited each summer since then. This year, on August 3rd, Laura Leventhal and I found 36 of the original 66 plants – a sharp decline from the 55 found last year. This means that 55% of the original cohort is still alive, with the survival rate this winter of 65%. Of the surviving plants, only three had more than one rosette.

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’s summary of the crossing done in 2011 can be found here.
