NICE! Plant of the Month

(Rivina humilis)

Family: Phytolaccaceae

Other Common Names: Rouge Plant, Rivina, Bloodberry. Baby peppers.

Type: Perennial herb. Leaves and berries are toxic to humans if ingested.

Natural Habitat: Native to the Edwards Plateau; found throughout Texas and most southern and western states in moist woodlands and in hilly chaparral.

Growth: 1-2 feet.

Deer Resistance: Moderately resistant.

Wildlife: Birds and butterflies.

Light Tolerance: Dappled shade, part shade to full shade.

Flowers: 2-inch spikes with delicate white and pink flowers; blooms March to October.

Fruit: Bright red berries from spring to fall.

Leaves: 1-3 inches long; deciduous; ovate to lanceolate, with wavy margins.

Water Requirements: Medium

Soil Requirements: Prefers moist, well-drained sites; sand, loam, clay, caliche.

Planting Instructions: Space plants 1 foot apart. Dig a hole at least two times wider than, but the same depth as the root ball in the nursery container. Sides of the hole should be irregular, not smooth. Remove plant from container, taking care to support the root ball. Loosen exterior roots gently with your fingers. If the plant is root-bound and cannot be loosened by hand, the outer roots may be cut in several places. Lift the plant by the root ball and place into the hole. Backfill hole, using soil that was dug out. Do not add any soil to the top of the root ball. Gently firm the soil with your hands, but do not tamp it down. Place 3-4 inches of mulch over the bare soil around, but not touching the base of the plant.

Watering Instructions after planting: Water deeply after planting to settle soil around roots. Then water every 7-10 days, as needed, during the first growing season. Before watering, check soil moisture at a depth of an inch or two at the edge of the root ball. Skip a watering after a rainfall of ½ to 1 inch. Maintain this watering schedule until the first fall. Reduce watering during the cool and winter months. In a “normal” year, no watering may be necessary during the fall and winter, but during a dry period, monthly watering may be needed. Second Spring and thereafter: Water monthly only during the periods of drought. Once established, native will survive with little supplemental irrigation.

NICE! Tip: Pigeonberry goes semidormant during dry summer months. Leaves return with the fall rains and turn a beautiful purplish-red color in the late fall. This plant thrives as a groundcover in part to full shade. Pigeonberry’s real attraction is that it blooms pink flowers and bears bright red berries simultaneously. The berries produce a red dye.

Look for the NICE! Plant of the Month signs and information sheets on your next visit to a participating Boerne nursery. And thank you for supporting native plants by using them in your landscapes.

About the Region

Fall Symposium 2025 Logo - Teach for the Future

Salado, the location of our Fall 2025 Symposium, lies at the intersection of two ecoregions: the Edwards Plateau (Limestone Cut Plain) and Blackland Prairie (Northern Blackland Prairie).

The Edwards Plateau area is also called the Hill Country; however, this general term covers a much larger area extending farther north. Spring-fed creeks are found throughout the region; deep limestone canyons, rivers, and lakes (reservoirs) are common. Ashe juniper is perhaps the most common woody species found throughout the region. Additional woody species include various species of oak, with live oak (Quercus fusiformis) being the most common. Sycamores (Platanus occidentalis) and bald cypress (Taxodium distichum) border waterways. This area is well known for its spring wildflower displays, though they may be viewed in spring, late summer, and fall, as well. According to Texas Parks and Wildlife, average annual rainfall in the Edwards Plateau ranges from 15 to 34 inches.

The Blackland Prairie extends from the Red River south to San Antonio, bordered on the west by the Edwards Plateau and the Cross Timbers, and on the east by the Post Oak Savannah. Annual rainfall averages 30 to 40 inches, with higher averages to the east. This region is dominated by prairie species. The most common grass species include little bluestem (Schizachyrium scoparium) and Indian grass (Sorghastrum nutans) in the uplands and switchgrass (Panicum virgatum) in the riparian areas and drainages. Common herbaceous flowering plants include salvias, penstemons, and silphiums. This area has suffered greatly from overgrazing and agricultural use. Few intact areas remain, though many of the plants can be found along county roadsides throughout the region.

Our fall Symposium host chapter, the Tonkawa Chapter, includes both of these ecoregions.
