Osteospermum "Passion MIx" is a lovely variety that blooms earlier from seed than most. It should still be started very early in the season however, preferably indoors, in order to gain some maturity before being transplanted to the garden. It grows well in full sun with a well drained soil and also makes a good container plant for a deck or patio.

Dipladenia is a tropical plant requiring full sun and a rich, moist soil during the growing season -- it does best when set outside for the summer. There are two varieties of Dipladenia. D sanderi rosea is
grown for its yellow-throated pink flowers and D.
Mandevilla splendens is larger-leaved with pink-throated
flowers. The large flowers appear in the summer, on twining
stems. Both can be grown as a climber, reaching 10' or
more, or can be pruned back once flowering is finished, in
order to maintain it as a bush. The glossy leaves remain all
year long under the right circumstances, but may drop when the plant is brought in for the winter.

In the winter, provide average household warmth (minimum 55F in
winter), and bright light. Water regularly
from spring through autumn, then reduce watering and water
only sparingly during the winter months. Mist the plant
regularly during the growing season, especially when in bud
or flower, and mist occasionally during the winter. Repot in
the spring, using fresh potting soil.
