Goldenrods are powerhouses – keystone plants that serve as hosts for more than 100 species of butterflies and moths, and rich late-season sources of pollen and nectar for countless beneficial insects followed by sustenance in the form of seed for birds.

Now Mt. Cuba Center, the native plant garden and research institution in Delaware, has published the results of its three-year trial of 70 different goldenrods – and their manager of horticultural research Sam Hoadley is here to tell us what they learned about the best goldenrods and how to use them in your garden.

Sam is the Manager of Horticultural Research at Mt. Cuba Center, where he evaluates native plant species, old and new cultivars, and hybrids in the famed Mt. Cuba Trial Garden. I always look forward to our conversations and getting his first-hand insights into each genus they explore there, and Sam will also be presenting a virtual class on goldenrod February 18 at 6:00 pm – 7:30 pm.
