Maple is one of the largest, most varied species of tree used in bonsai cultivation.
Its leaf size, branching and wood growth characteristics make it a great candidate for addition to any collection.
They do not do well indoors at any time of the year.   In the fall the leaves turn colors, and drop.  They are bare from late fall through early spring.
A Norway Maple should not be kept indoors in winter unless it is in a location where the temperature never goes above 40 degrees.
