This annual makes a wonderful garden ornamental that blooms fragrant white flowers in late summer and is pollinated by hummingbirds and butterflies. Be sure not to plant next to your vegetable garden since this nightshade plant can transmit diseases easily to other members of the nightshade family (i.e. tomato, eggplant, peppers). Grow in fertile, moist but well-drained soil with full sun. 
Surface sow the seeds after last frost by lightly pressing into the top of the soil. Barely cover the seed as this plant needs about 12 hours of sunlight to germinate.  You can also start the seeds in doors 6-8 weeks before the last frost. Germination occurs between 1 ½ and 3 weeks.
