Question
Viburnum in full bloom 5-14-2025 in woods adjacent to Flume Pond along Buzzards Bay in Falmouth, MA. Long silky hairs along veins on back of leaves. Keys to V. dentatum or rafinesquianum but not clearly to one or the other. Surface of flower (around ovary under scope) shows no cilia. Other Viburnums here right now are only in early flower bud - a week at least away from flowering (like the Dentatum with round leaves).
Answer
Dear cknox, good morning. You appear to have photographed Viburnum dilatatum or V. wrightii, two non-native species from Asia that have minute, unstalked glands on the leaf blade surfaces. I can't tell you which one for certainty without additional images or a collection that I could inspect. Feel free to reach out to me directly (ahaines@nativeplanttrust.org) and we can get this plant identified for you (note: if it has passed flowering, that is acceptable, many of the characters that identify these two species are present throughout the growing season).
