Pelargoniums are from the Cape region of South Africa. Voodoo will produce some lovely maroon flowers with dark purple/black markings. Dead head the old flowers to keep them flowering throughout the summer. They are best grown in a free draining soil/compost in a sunny location. Height and spread 45cm. If you live in a mild area you may be lucky enough to over winter outdoors but if not grow them in pots and over winter indoors.
