This tropical favorite is perfect for growing along fences and in butterfly gardens. Mexican Petunia produces trumpet-shaped flowers that are a favorite with pollinators. The deep purple flower and dark foliage make a beautiful contrast when planted by yellow or orange flowers. Try pairing it with a Thyrallis and a Crossandra for a jewel tone garden. Ruellia is a fast grower and can spread quickly, so make sure to prune it frequently. Avoid planting Ruellia in any area that borders a preserve or naturally wooded area since it can become invasive in unmanaged areas such as these.
Ruellia flowers continuously under direct sun so plant in areas that get about 6-8 hours of sun each day. If planted in shady areas, the plant will not bloom as much, and the leaves will be sparse. Water daily when planted and regularly once it is established. Fertilize with a well-balanced fertilizer about three times during the growing season. Prune liberally at any time to keep it to the desired size and shape.
Note: These plants are grown for decorative purposes and are not intended for human or animal consumption
