Gardens are becoming more and more numerous in the Alps; almost every year lengthens the list. For present purposes, however, we will content ourselves with visiting three only - three of the oldest and most representative; and, as Alpine plants may be roughly divided into two sections - the limestone-loving and the granite-loving - we shall be careful to choose a garden in a limestone, and one in a granite district; the third being one which is purely scientific, as apart from the more decorative and protectionist aim of the other two. We will also visit them in the order in which the writer last saw them in the Spring and Summer of 1909.
