Tender evergreen shrubs from China and Japan, belonging to the
Rubiaceae family. Gardenias have deep green glossy leaves and
waxy white single or double blooms. They are highly scented and
have been prized by ardeners for this reason and for their stately
Gardenia jasminoides is a warm weather shrub requiring a minuimum
temperature of 60F. The shrubs thrive in a rich sandy loam and
make excellent borders or potted plants, outdoors or in.
Outdoors, they should be planted in an area where they will receive
some shade in the heat of the day. The soil should be rich loam
with a pH of 5.0 to 6.5. It is beneficial to add generous amounts
of rotted leaves or compost to the soil.
When growing the gardenia as a house plant, be prepared for some
effort. Care must be taken to keep the humidity high and to keep
the plant from drafts, the soil acidic enough (between 5.0 and 6.5),
and the light high. Their scent is very strong and can be overpowering
in a small room, so choose your location according to your tastes. If
your water contains large quantities of calcium, you can add some lemon
juice to it before watering as this will lower the pH of the
water. Without enough acid in the soil, the plant cannot process
the nutrients in the soil properly and the leaves will yellow and drop.
Propagation is performed by air layering or by taking softwood
cuttings in the spring. Cuttings of about 3 inch in length are
inserted into sandy peat. The cuttigns should be placed in a
propgation case or covered with plastic or glass and kept warm with
bottom heat and the soil kept moist until roots are formed. At
this time, the cuttings are potted separately in a medium comprised of
equal parts loam, peat and well rotted leaves or compost with a
generous sprinkling of sand. Young plants are kept warm and moist
with frequent mistings. Bushy plants are assured by pinching out
the tips of the new shoots during the summer.
The plant has been used a perfume and to treat headache,
toothache, hepatitis, inflammation, nervous disorders and sores.
