Coreopsis lanceolata ‘Sterntaler’

4 Photos


Coreopsis lanceolata ‘Sterntaler’ proved to be reliably hardy throughout the entire trial. The plants did not flower the first year; however, that was not uncommon. By the second year, they developed into large, vigorous plants that were full of flowers. Unfortunately, downy and powdery mildew both became a problem during the summer of 2013. Plant quality did deteriorate, but not enough to kill the plants. ‘Sterntaler’ looked great when it flushed out new leaves the following spring, but they again deteriorated after flowering, likely due to a persistent downy mildew infection. It’s worth noting that Coreopsis lanceolata and its cultivar ‘Sterntaler’ were among the few non-rhizomatous plants to survive the entire trial.
