One doesn't usually think of maples as common Texas trees however native stand of sugar maples (Acer saccharum Marsh.) still survive in TX Lost Maples Canyon as holdovers from the last ice age. Sugar maples are a common landscaping plant but they are heavy water users. The native red maple (Acer rubrum), with its beautiful red seeds and leaves, is much more common. Both will have the five-pointed leaves like one sees on Canadian flags and beer bottle labels. Both will also produce the "helicopter" seeds hat twirl and spin as they fall from the tree.
In late winter/early spring maples will begin producing leaf buds. These tiny buds and the newest leaves they produce make a good woodland's nibble. They can be added raw to salads or even cooked like spinach.
Maple seeds can be roasted like pumpkins seeds. Remove the seeds from their "wings" before roasting. The young leaves are best within the first few weeks of appearing and are delicious raw and wonderful when added to salads, especially with a tangy oil/vinegar dressing.
The inner bark is mainly a survival food. Cut long vertical strips of the bark off the tree, not exceeding more than 10% of the width of the tree trunk. Taking more will most likely kill the tree and even just taking 10% will greatly weaken it. The inner bark looks like a brown paper bag. Slice it into thin strips then boil it for several hours to make a mush. It will still tastes pretty much like a boiled paper bag.
Tapping sugar maples is best done in late winter when daytime highs are 40-50F but below freezing at night. Texas weather rarely gives such a clear sign so some luck is involved in getting the timing right. Note that it takes boiling down 40 gallons of sap to get one gallon of syrup.
