Winter flowering plants are not too plentiful, at least such as will bloom in the cool temperature of a greenhouse; we have many fine winter flowering exotics, but they either require a hothouse temperature to bloom freely, or are more difficult to manage during summer; we are indebted to the Celestials for many of our most valuable winter flowers, Azaleas, Camellias and among others that beautiful little gem the Chinese primrose. They are all of hardy and robust habit, and are thus within the reach of all, so far as cultivation is concerned, a recommendation of much importance to those amateurs who cannot devote much time to their collection. It has often occurred to me when visiting amateurs’ greenhouses, that they would derive much more pleasure from their labors were they more select in the choice of their plants, choosing those only of known hardy and free blooming qualities, instead of aiming at a varied assortment, often expensive, and rarely satisfactory. I was more deeply impressed with this fact during a visit to an enthusiastic amateur last winter. On entering his greenhouse I was struck with the gay and cheerful appearance it presented, and it was only when about leaving that I observed the only plants in flower were a few Camellias, two or three Cinnerarias, and a quantity of Primulas of various colors, but these were so well arranged and set off with a profusion of healthy foliage, and the Primroses showing such fine rounded trusses, that I am confident not one person in ten would have noticed this simplicity of its production. Although this plant is very hardy, I am aware that many amateurs are not so successful with it as they would wish. This, I presume, arises principally from its liability to decay if kept too damp at root, either from using pots of a large size, or supplying water too freely. Four and six inch pots will be found of ample size, not that a plant will not grow in a pot three feet in diameter as well as it would in one inches. The only difference would be that, in the former, the plant would probably require water once a month and the latter daily.
