in Gardening, a knot or button put forth by the branch of a tree in the spring. The word is formed from the French bourgeon, which signifies the same, formed from the Latin burrio, of burra. Burgeon amounts to the same with what is otherwise called eye, bud, or germ. Frosts are chiefly dangerous when the burgeons begin to appear. The burgeous have the same skin, same pith, same ligneous body, and the same insertions as the stalk.
