Italian Villas and Their Gardens 

Though it is an exaggeration to say that there are no flowers in Italian gardens, yet to enjoy and appreciate the Italian garden-craft one must always bear in mind that it is independent of floriculture.The Italian garden does not exist for its flowers; its flowers exist for it: they are a late and infrequent adjunct to its beauties, a parenthetical grace counting only as one more touch in the general effect of enchantment. This is no doubt partly explained by the difficulty of cultivating any but spring flowers in so hot and dry a climate, and the result has been a wonderful development of the more permanent effects to be obtained from the three other factors in garden-composition—marble, water and perennial verdure—and the achievement, by their skilful blending, of a charm independent of the seasons.
