False blue indigo's spikes of clear blue flowers in late spring can nearly carry a border by themselves. They also make great cut flowers. Large, inflated nearly black seed pods set in after flowering, giving this plant another interesting element. It is low maintenance and will look great in any natural or informal setting.

The intense scarlet red blooms and yellow centers of this bedding plant will stop you in your tracks. ‘Cosmic Red’ blooms all summer and looks great at the front of the border and in containers. As with other cosmos cultivars, grow this plant in full sun and moist, well-drained soil. The already hypnotic color will intensify as light levels increase.
