Clusia rosea - Autograph Tree

interestingly named tree, D1. I have heard of Banyan trees are they related to baobabs?

No, Baobabs are related to the Hibiscus. They in the same family, Malvaceae.

Ficus or Banyan trees are in the Moraceae family (Mulberry tree family). You most likely can grow Mulberry trees easily there.

I never really thought about it til you mentioned it, D1. Yes, Morus alba is hardy to zone 3 and I'm in zone 4b. will have to give this some consideration and do a search for availability. Thank you! I was planning a small clump of Gleditsia (honey locust) as they are zone 4 hardy perhaps, depending on availability and price I can do the same with Morus.

Morus alba can get really large, very fast (like most Ficus species). Morus nigra (fruiting Mulberry) tends to be smaller.

Morus alba has a weeping form as well as the standard. I think I'd prefer the standard. given how fast the robins eat the red elderberries (not edible by humans) I don't think I'll have fruit to spare on the mulberries. I'd rather have the fruiting trees because they attract birds. the only Morus mentioned in my encyclopedia of Canadian trees and shrubs is the alba. the gleditsia have pods of bean-like seeds which I think might be attractive to the squirrels but it's the yellow lacy foliage that I'm planning to add. I have black walnut(3), hazel(an approx. 300 square ft thicket), and beeches for nut/seeds and a very healthy population of red, gray and black squirrels! I have had Amur Maples in my previous garden and like the hardy attributes of all Amur species and I'm kind of taken with the description of the Phellodendron amurense (Amur Cork Tree)which has a very triangular shape with open branching... and it's listed as mildly invasive... (just my kind of tree). It's also listed as hardy to zone 3. Where I'd find them is a mystery though.

I guess Morus nigra would be more of a challenge. I read it's more tender. Morus alba is a very fast grower. It should do very well there.

It sounds like you have a lot of wildlife there. With all those fruit-bearing trees I guess it attracts a lot of those animals. :>))
