Certain woodland plants help ease our transition out of peak spring ephemeral bloom. Just as we start to miss the Erythronium and Anemone, these stalwarts come into bloom and herald the rest of the season in the flowering understory. …

If we assigned a persona to every genus of plants, that of Corylopsis would be owned, I think, by Audrey Hepburn. Elegant and fair. Strong-willed. Independent. No rough edges.
