Common Geranium, Garden Geranium, Zonal Geranium (Pelargonium  hortorum)

Cultural Practices:
The geraniums have trouble surviving the summer heat. They need shade in summer, and care should be taken to keep their roots cool by using mulch and making sure that if they are in a pot, the pot stays in the shade. Fall is a good time to plant geraniums in Phoenix, so that they grow slowly until the main blooming time in spring. In colder climates, plant them after the last frost date.
Sow at 70 to 85F (21 to 29C). Plant 8-10 week transplants 1 foot apart (30 cm). Remove the spent flowers to promote new buds.

Blooming Habits:
White, orange, pink, red or purple flowers.
