House plants improve your indoor environment in many ways. Healthy plants look nice, contribute to a calming atmosphere and filter pollution from the air. Some indoor plants and trees also smell nice; their scented leaves or flowers contribute a lovely aroma to your home. Choose a scented indoor tree or houseplant suited to the light and humidity conditions of your home and enjoy its natural scent for years to come.
Pink Jasmine (Jasminum Polyanthum)
The pink jasmine is simple for even beginning gardeners to grow indoors or out. It requires bright, indirect light to bloom and its vigorous growth may necessitate training the vines along a wire or trellis. It is also an attractive hanging plant. Pink jasmine features clusters of five-petaled pink-and-white flowers that produce a strong, sweet scent.
Pelargonium (Pelargonium sp.)
Pelargoniums -- also called scented geraniums -- come in a vast assortment of styles, colours and scents. The fragrance of a pelargonium comes from its leaves, which are faintly scented until they are crushed. Most pelargoniums produce clusters of brightly coloured but unscented flowers. The leaves of some varieties smell like mint, roses, cinnamon, apple, lemon or coconut. Pelargoniums are low-maintenance houseplants and the leaves can also be used for flavour in cooking.
Gardenia (Gardenia Augusta)
Gardenias have very specific lighting, fertilisation, temperature and moisture requirements, but many indoor gardeners feel that the glossy green shrub is worth the trouble. Under the right conditions, gardenia plants produce waxy, pure-white blossoms with a strong, sweet fragrance that can perfume an entire room.
Meyer Lemon (Citrus Meyeri)
The Meyer lemon is a dwarf hybrid tree that grows well and will even fruit indoors. They need acidic soil, consistent humidity and five to six hours of bright light every day, but the light, sweet scent of the lemon flowers will repay the effort. The lemons have a sweet aroma as well, and the Meyer lemon is a prolific bearer once it is established.
Hyacinth (Hyacinthus Orientalis)
It is simple to force a hyacinth bulb to bloom indoors even in the winter. A bulb placed in shallow potting soil or even a bed of stones, kept moist and exposed to light will bloom in four to six weeks. Hyacinth flowers are large and very strongly scented and they come in shades of purple, blue, pink and white. After the blossoms have faded, the bulbs can be transplanted in the yard to bloom again in future years and new bulbs forced for indoor use.
