The more homely and familiar hyacinth is not only delightful in form, color, and odor, but may be recommended as a "safe investment," as it seldom fails to flower and needs comparatively little care.
The mahernia is another desirable fragrant plant. It is very effective in a hanging-basket. It comes in flower about the first of February, and its tiny yellow cups are brimful of delicious odor. A home-bred mahernia makes fine foliage, but seldom blooms abundantly; it is, therefore, best to procure the plant from the florist when fully budded. It will then flower well in a sunny window, and for three or four weeks one's room will be as sweet as summer. The wax-plant, though properly a summer blooming plant, sometimes flowers in winter. Its blossoms are very odorous, especially by night, and in structure and color they are exquisite. It is a long-lived plant, easily raised and tended, and, being a climber, may be tastefully trained on a trellis, where, with its glossy, rubber-like leaves, it is very effective. The petunia, as a window plant, blooms freely, and the white variety is fragrant--especially by night. The plant is rather ungainly in its habit of growth. To conceal its scragginess of structure twine its stems among other foliage on your stand, and place it close to the glass, and you will find it pretty and effective. And now that sweet-smelling plants are under consideration, may I not give you the details of an experiment with the common lilac as a house plant? It was made some fifteen years ago, and before I had the slightest knowledge of lilac-forcing, which is now quite common among our florists.
Early in December a stout, low bush of the hardy purple variety was, with the aid of a pickaxe, dislodged from the frost-bound earth, and with its frozen ball of sod still adhering, thus treated: a large nail-keg, having an auger-hole in its bottom on which some bits of crock were strewn, was filled to about half its depth with warm stable manure; on this the dry leafless bush, with its frozen soil, was set, and the keg filled in with mellow loam. After a good watering, the keg was placed in a deep pan, which was then filled with boiling water, and the whole set near a huge hall stove. The hot water was daily renewed at the bottom, and before many days leaf and flower-buds began to swell on the hard, bare stems of the bush. When these were well formed and the tiny buds quite distinguishable among the pale green foliage, the lilac was removed from its dim corner beside the stove, and given an entire east window in the long hall, where the temperature ranged from forty to sixty, and sometimes as high as seventy degrees. In about two months from the time of housing fourteen large and perfect clusters of pearl-white lilacs rejoiced our eyes. These blossoms were far more delicate in odor than out-door lilacs, and made a delightful atmosphere of spring-time in the homely old farm-house which was then our dwelling-place. We had, too, the novel pleasure of surprising our friends with clusters of fresh lilac in February.
