Crossandra Infundibuliformis Acanthaceae Firecracker Flower Plant

09:08 This striking plant, also known as Crossandra undulifolia, is a small shrub from the rain forests of southern India and Sri Lanka. Its shiny, dark green leaves with wavy edges are held in opposite pairs and are 2V2-5in/6.5-13cm long. 


From spring to late fall, the flowers—in shades of yellow, orange, and red—rise in twos and threes from upright tufts of green bracts. Each has a tube-shaped base, but flares out into a lobed disc up to PTinAlcm wide. Even young specimens will flower readily, but after about two years they tend to lose their vigor and should be replaced.  crossandra2binfundibuliformis2bhouse2bplant2bpotted2bimage-8207085 The form ‘Mona Walhead’ has salmon pink blooms; those of Crossandra pangens are yellow. Crossandras are good for groups, since they flourish best when surrounded by other plants and enjoy humid conditions. acanthaceae2bhouse2bplant2bimage-9662342 Check for red spider mites; regular misting will help to discourage this pest. crossandra2binfundibuliformis2bplant2bpotted2bimage-6978848 A reluctance to flower may mean that the plant is in too much shade. Move to a brighter place and pinch off some leaf growth to stimulate flower buds. crossandra2binfundibuliformis-7196007 Falling leaves and a drooping appearance may indicate that the plant is standing in a cold draft; move it to a warmer place. firecracker2bflower2bpotted2bplant2bpic-6473966 FACT FILE
