This one is Maraval. Last year, this tree was the first to bear, having two chestnut clusters last year. This year, there are about 10 female flowers. Hard to say because they are so small and so high on the tree.
Precose Migoule also has a couple of female flowers, and lots of male flowers.
The very small Marigoule is vinally growing nicely, and has a few catkins of male flowers.
The Marissard seedling has no flowers. Nice looking tree, but no flowers. It's probably a mistake to buy a seedling, even if it's named.
The plan was to have them close enough together to pollinate each other. But with the small size of the trees, and the small numbers of male flowers on the trees that just started making them, I have tried to hand pollinate using catkins of the other tree. Unfortunately, doing so I broke off one of the two potentially bearing branches of the Precose Migoule. That was going to need pruning anyway, but a few curse words were said.
