Ornamental Maple's

[English River Maple]

Anyone ever tap an ornamental (deep purplish/reddish colored leaves) maple tree? If so, did you test the sap? Roughly how much sap in comparison to red's, sugar's etc. Random curiousities...

[Clarkfield Farms]

Most red-leaved (that aren't Japanese maples) will be variants of Norway maple, with similar sugar concentrations.
