Ruellia species is a broadleaf evergreen or semi-evergreen perennial with green foliage. In summer purple flowers emerge. Grows well with sun and regular water. Does well in well-drained soil.
Ruellia species are unusual little plant that grows small trunks and reminds me of a dwarf cordyline with large purple flowers. I have been able to over winter this plant by mulching 4 to 6 inches in winter. A great plant for the hardy tropical garden.
Foliage: strap like foliage on small trunks
Flowers: nice large purple flowers 1 to 2 inches
Height: 6 inches to 1 foot tall maybe larger in tropical gardens
