I want to plant edible, non-cultivar viburnums which are native to my local area (Northern New Jersey). These would be: V. lentago (Nannyberry); V. Prunifolium (Blackhaw); & V. trilobum (Cranberrybush). In addition, I would plant V. nudum (Witherod) which is not edible.

QUESTION:

Must I plant a pair of EACH individual specie in order for polination to occur for fruiting, or will they mutually polinate eachother, despite being different species?

Note: I do understand that when they are of the same specie, them must not be too closely related (i.e. two Viburnum lentagos must not come from the same mother plant); I am just wondering if, for instance, V. lentago and V. nudum, etc. could sucessfully polinate eachother.

Thanks,
Steve

p.s.: If anyone is growing an American Persimmon or Salix discolor that is greater then 20', please let me know - I'm looking for a full photo beyond the score of what I could find online.

I am no expert though. I would try to find someone or even search the old threads to find some info from Kevin z5(?) or Viburnum Valley. They are both what I would call experts on viburnums and have posted some great info on this forum on this topic over the years. If you have no luck doing that, I would hop on over to the shrubs forum.
