In persimmons you can get fruit formation without seeds, but in some species if you don't have seed formation then you don't get fruit. For example, in citrus you can have seedless triploids or there are known genes that cause seedlessness. Things that can affect seedlessness are things like ploidy level or perhaps some kind of genetic barrier. I assume you are just talking about interspecific hybrids in general? Many are fertile and have been used in different breeding programs. In regard to the seedlessness of interspecific hybrids, I don't think you can make a general claim one way or the other as several factors can affect that. I think it would be cool, but I'm not going to do it. It may require some extra effort, like embryo rescue or ovule culture. ![]() So while it may not be impossible, I can't find evidence of anyone having made the cross before. ![]() florida are in the same subgroup) and they have different fruit structure. They are grouped in different subgroups (C. That would be an interesting cross, and I've wondered about that myself, but I don't know how sexually compatible they are.

Starting with maples, three common ones are Sugar Maple, Acer saccharum,Īsh trees which are in decline due to Emerald Ash Borer, In an effort to not get too far into the woods (weeds) not pun intended, I will just share one or several examples of some Genus, but not all species within the Genus. When looking at bud arrangement, trees with lateral buds opposite of each other include Starting with deciduous trees, I’m reminded something I teach my Environthon students – MAD – BUCK. In addition, you are encouraged to create a site map of the trees in your home landscape and documenting as you install new ones. Arboretums are a great place to study trees since many plants are labeled. If you commit to embracing tree identification as a four-season activity, observing the tree in spring, winter, summer, and fall (even going as far as to label it), you can become proficient at tree identification.
