In 2022, the CGW chose about 40 cultivars each of salvia, petunia, and calibrachoa to showcase the newest genetics. The salvia bed provided a stunning display at the entrance of the garden for visitors and pollinators (especially hummingbirds). Among the petunia and calibrachoa, we did a paired T-test trial, with plants either being treated with mycorrhizae or not. Though most of the petunia benefited from the mycorrhizae treatment, the calibrachoa didn’t respond because they were struggling in our high-alkaline soils. Still it was interesting to observe that some calilbrachoa did pretty well despite our high pH in the garden beds which shows the improved genetics on some of those cultivars.
