Plant Crossandras in an area that gets about 4 to 6 hours of full sun during the day.Protect the plant from the grueling heat of the hot summer months. Firecracker flower prefers fertile organic soil that is well-drained. Avoid planting in wet areas since they do not like having wet feet. Water daily when planted in the landscape until established. Water thoroughly, but do not soak. After established, water as needed, especially during the hot summer. If planted in containers, water consistently when the top inch of soil feels dry to the touch. This lovely plant can also be enjoyed as an indoor plant as long as it has plenty of bright light and warmth.  In zones 9 and above, Corrandras are perennials. In zones 8 and below, they are regarded as an annual or use as a lovely container plant.
