Ceropegia woodii is a flowering plant in the genus Ceropegia (Apocynaceae), native to South Africa, Swaziland, and Zimbabwe. It is an evergreen succulent trailing vine that grows to 2-5 cm in height and spreads to reach up to 2-4 m in length. Its leaves are shaped like hearts, about 1-2 cm wide and long. When exposed to sufficient light they have a deep green colour; under insufficient lighting the leaves are pale green. With age it develops a woody caudex at its base. The roots, and occasionally the stems, will often develop tubers. On the stems these form at nodes and are likely the reason for the common name of rosary vine.
The flower is in general form similar to those of other Ceropegia species. The corolla grows to 3 cm in length and is a mixed colouring of off-white and pale magenta. The five petals are a deeper purple.
Ceropegia woodii is a very popular houseplant, often grown in hanging baskets so the long trailing branches can hang down with their leaves spaced out like a row of large beads. Several cultivars have been selected, some with variegated leaves.
It requires excellent drainage, should be watered only when dry, and should never stand in water. Excess water should be removed from plant saucer after watering. It can be grown outdoors only in subtropical and tropical areas, with a minimum temperature of 15 °C. Partial shading is useful when the plant is grown outdoors.
Mandevilla, sometimes also wrongly called Dipladenia, is a genus of about 100 species, mostly tropical and subtropical flowering vines belonging to the Apocynaceae family.
Mandevilla is native to Central and South America and many Mandevillas come originally from the Organ Mountains forests near Rio de Janeiro in Brazil. The genus was named after Henry Mandeville (1773-1861), a British diplomat and gardener.
Mandevillas develop spectacular flowers in warm climates. The flowers come in a variety of colours, including white, pink, yellow, and red. As climbers, Mandevillas can be trained against a wall or trellis to provide a leafy green and often flowering picture of beauty. They have a tendency to attract insects like mealybugs and scales.
Mandevilla is also considered to be toxic.
Stephanotis floribunda (Madagascar Jasmine) is a flowering climbing plant. Its trumpet shaped blooms are in season year-round and are a popular component of bridal bouquets. It is a vigorous climber, tough stemmed, bearing dark green leathery leaves, which grow in pairs at regular intervals along the vine. Stephanotis floribunda grows best in sunny, tropical conditions or indoors on a sunny windowsill. They can be moved outside or into a greenhouse during the summer.They can grow from 2-6 meters, and are widely cultivated as garden plants.
The flowers are waxy, star-shaped and highly scented, about 3cm long, in clusters and are produced in summer. Flowers fade to yellow after several days. They are a favourite in weddings, used in bridal bouquets, corsages and decorations. Normally the plant has to be a little old and root bound to start flowering. Once it does, the result is very rewarding. The flowers are long-lasting and sweetly scented.
Propagation is by cuttings or by the seeds, which are produced irregularly.
