"Walnut or relation" = Juglans species or perhaps even another genus, although first off you should compare yours for instance with J. cinerea, which produces some quite similar leaves and fruits. There are also numerous examples of more than one Asian walnut species on West Coast properties, these are more like butternut than English walnut and the several species of black walnuts. People I've talked with who were occupying sites up here with landmark butternuts or Asian walnuts on them have never known what the trees were, one party came up with the name "white walnut".

Yes Yedidyah that is a mulberry tree.

Yes Tony, like Lisa said, those are hard to identify. You will have to wait for the fruit, and then when you cut into it. The color of the flesh, plus the size of the fruit should be a help. My cactus is blooming too for the first time this month, not fruit set yet. I keep hoping. I have the physical graffity, and yellow variety, if you are interested in cutting. Veronika

Don't eat that thing!!! Clusia rosea is a tree found in the Caribbean, including the Bahamas, Hispaniola (such as in Los Haitises National Park), Cuba, Puerto Rico, and Florida. The tree produces a fleshy, light green but poisonous fruit; once the fruit has split, the seeds are favored by birds and other wildlife. This plant is cultivated as an ornamental plant, for its flowers, foliage, and fruit. It is planted in gardens as a fruiting and ornamental tree in sub-tropical climates, and used as a houseplant in many climates. Local PR Spanish name is Cupey http://en.wikipedia.org/wiki/Clusia_major
