Aloha I have these plants I cannot Identify all 3 are deciduous the first I think is an elm but I am not sure the second has not leafed out yet but has cone-like inflorescences the Third is semi evergreen and re minds me of a huckleberry or vaccinium. sorry i ahve never seen it flower all are planted in my complex but the gardener says it is job security for him if he is the only one who knows the names of the plants in the gardens. If anyone could help I'd appreciate it Abientot Pierrot
2. reminds catkins of birch or its relatives. You should check them when the catkins and leaves are open. Talking about birch relatives. Check for the first picture some Ostrya (virginiana or knowltonii). They also have pleated leaves.
1 - agree with Hornbeam Carpinus betulus. 2 - probably Persian Walnut Juglans regia. It'll be a lot easier when it is out in leaf.
Thank you all the second one has leafed out now and has the typical juglans foliage. I will ahve to wait a couple of weeks til the flowers are out thanks a lot
