Culture Notes
Wild Petunia is a native wildflower found throughout the eastern part of the United States' woodlands. They spread and are known as strong growers under adverse conditions. Wild Petunia has light green leaves that are medium in texture. Blue or violet flowers appear on this perennial in the spring, summer and fall. These flowers are showy, and their nectar is appealing to various species of butterflies.
Wild Petunia may be used as flowering ground cover and in front of perennial borders. They are attractive when massed together or planted in a container where flexible stems droop over the pot. They would make an attractive hanging basket.
Place Ruellia in an area of the landscape that receives full to partial shade. These species will grow best in well-drained soils and are very drought tolerant. If Ruellia is frozen to the ground in the winter, regrowth should occur from the roots.
These plants may be propagated by seed or cuttings. Ruellia can spread, as it readily reseeds itself. These plants bloom profusely, especially in the spring and fall.
