Although the current wave of popularity enjoyed by the rose began in the nineteenth century under the sponsorship of the Empress Josephine of France, the rose has been a cherished inhabitant of gardens since earliest times. In this respect it shares the esteem of gardeners with the lily and violet. However, unlike those flowers, its popularity has never waned. Its close association with mankind has led to its inclusion in the customs, languages and cultures of the peoples of the western world. In tribute to its beauty the Greeks gave it the title “Queen of Flowers”—a title which it well deserves if we are to credit the many attempts to grow it in the myriad climates and soils of the earth.
The genus Rosa is widely distributed over the north temperate zone. In a plant group whose members are adapted to the many different climates of this broad geographical area, it would be strange indeed if there were not at least one rose which would flourish in almost any given climatic condition.
Because the climate of Iowa and its neighboring states is rigorous and highly changeable, certain handicaps are presented to the rose grower living in this area. However, it is possible to select rose varieties that may be grown with a minimum of care in locations suitable for other sun-loving plants. The experienced gardener will carefully study the requirements of his particular situation before choosing the roses to grow in his garden.
