I recently stumbled upon this gray dogwood (Cornus racemosa, Cornaceae) along a ditchbank on the edge of a floodplain forest near Blissfield Michigan. The white berries were quite striking against the deep red-purple fall foliage.
The large number of white berries are popular food for birds who help distribute the seeds. I saved some of these seeds hoping to grow one to plant near my house. I’ll have to leave them in my refrigerator until spring to stratify them. I could leave them outside as nature intended, but they’ll be safer in my fridge. I read that scarifying the seed coats with acid can improve their germination rates, but I’ll have to read more about the technique.
