NICE Summer 2026 Plant of the Season

Pigeonberry (Rivina humilis L.): Perennial ground cover for shade

Description: Pigeonberry (Rivina humilis L.), also called Coralito, or Rouge Plant, is native to the southern US as far north as Oklahoma. It is a small shrubby perennial that can grow from 18 to 34 inches tall in North Texas with smooth (glabrous) leaves that are 1 to 3 inches long. It has an upright habit. Pigeonberry is perennial and deciduous, going dormant over the winter in North Texas.

Flowers and Berries: Pigeonberry has very small pinkish-white flowers during most of its growing season that give rise to brilliant red berries. The plant often has berries and flowers at the same time.

Planting sites: Pigeonberry can be planted in dappled, part or full shade and in many types of soils.

Watering Instructions: Pigeonberry should be watered after planting and again every other week during its first growing season. Once established, Pigeonberry will grow with existing rainfall because of its drought tolerance;
during extreme drought, it may go dormant, but will re-emerge from the soil after the first rainfall.

Comments: Pigeonberry is an outstanding addition for shady areas that are not irrigated. Its wavy foliage is very attractive and its red berries are irresistible to birds and will attract a variety of birds to your yard. However, neither the berries nor other parts of this plant are for human consumption. Consider using Pigeonberry instead of hosta in shady areas. Pigeonberry won’t need the supplemental water that hosta must have to survive our North Texas summers.

About the Region

2026 Fall Symposium Logo

This low-elevations region of Texas extends inland from the barrier islands, about 60 or so miles, and stretches from Brownsville to Louisiana. In total, it covers about 9.5 million acres, with a high point of 150 feet in elevation. More than 1000 species of plants can be found in this region. On the southern end, species more common in Mexico (such as Sabal mexicana) and Central America occur.

The barrier islands provide us with dune systems, and clay flats to the inland side, which have species found in these areas alone. Many plants here, such as Ipomoea pes-caprae (beach morning glory), can be found throughout tropical regions of the globe. I’ve encountered the same species on the beaches of Guam.

Once inland, vast marshes and wet prairies occur. Occasionally, oak (Quercus fusiformis) groves can be found. Common grasses include species of Bothriochloa, Paspalum, and Sporobolus; eastern gamagrass (Tripsacum dactyloides); and switchgrass (Panicum species). Many rivers and creeks cut through the Gulf Prairies, and along these riparian areas various species of trees, Sabal minor, and other plants adapted to clay soils can be found. Due to overgrazing, farming, and fire suppression, woody species such as mesquite (Prosopis glandulosa) and huisache (Acacia farnesiana), and invasive species such as chinaberry (Melia azedarach), Brazilian pepper (Schinus terebinthifolius), and Chinese tallow (Sapium sebiferum) have increased and displaced our native flora.
