They grow well at the coast and add a touch of brightness in dull corners. During the hot dry season they are best grown in pots or tubs, during the rains and cooler periods sow the seeds directly into the soil. The seeds germinate easily and in no time there is a wonderful display. Watch out for Spider Mite and Leaf Miner. Updated 10/9/2018
