A hardy low maintenance annual with striking blossoms.  Tollerates low water conditions but prefers medium moisture well-drained soils.  Prefers full sun to  light shade, stems will droop with too much shade.  Taller plants may need staking.   Seeds can be started indoors 6-8 weeks before last frost, or in mild winter climates can be seeded directly outdoors in the fall.
