Cross pollination of native fruiting shrubs
I'm trying to create a more bird-friendly environment in my yard. I'd like to plant serviceberry and/or viburnum. I have light shade under some tall locusts and a tuliptree. The space is not huge--do these species need several plants each in order to flower? I was leaning toward viburnum nudum or trilobum and amelanchier grandiflora, but I'm flexible.
