    I didn't realize that Acer griseum trees would be male or female, or as Acer griseum - Wikipedia says, they are Androdioecious: having male flowers on some plants, bisexual ones on others. I saw a group of four trees today at the edge of Stanley Park, two with a lot of samaras now in the winter, and two with no samaras. I just learned that a "distinctive feature" of Acer negundo is the "long chains of of keys hanging on bare winter branches" (Straley, Gerald B., Trees of Vancouver, Vancouver, UBC Press, 1992, p. 60). Surely it's just a curiosity that both trees with persistent samaras have three leaflets (or sometimes more, in the case of A. negundo). Presumably, "distinctive feature" means that it's not common. At least I can distinguish those two.

    Here is one of the male trees.

    I wouldn't conclude the barren specimens were staminate without first examining their flowers.

    1st March 2021 and my new Acer Griseum arrived, I was already informed by text yesterday that it would. It was in a 10ltr pot and had a very healthy root system. An 8 year old tree. Around 7-7ft 6 inches tall with peeling bark already showing near the base of the trunk.
    Planted in a part of my front garden to receive full sun in a raised area to allow for water to flow away from the trunk.
    The bamboo cane will be removed in a week or two.
    I will update this thread over the coming years on it's progress. I'm so very pleased.

    On a city street, bark and seeds. (And there are many seedlings underneath in the immediate vicinity.)
