Abstract
This research report describes the performance of several cold-hard “panicle” (H. paniculata), “smooth” (H. arborescens), and “oakleaf” (H. quercifolia) hydrangea as landscape plants and for cut flower production in Durham, NH. We established a replicated planting of sixteen newer hydrangea cultivars at Woodman Farm in summer 2020. Preliminary data from these young shrubs indicates that there are wide differences in flower production, stem quality, flowering time and duration, and postharvest floral quality – among other traits.
