Still about Viburnums: berries
Greeetings. I am new to the forum. I have searched for an answer to my question, but I'm still confused.
We are planting for birds in our back yard. We live in central Iowa, zone 5. Along with some of the other bird-attracting plants we have planned, we want to plant viburnum, but I'm confused about how to get a good berry crop. I read about needing to plant more than one clone. Is this true for all varieties of Viburnum? Does "more than one clone" mean more than one plant or more than one variety?
While I'm at it, may I also ask which varieties are most attractive to birds for my zone?
