Rhizoma Perennial Peanut (Arachis glabrata)
Rhizoma perennial peanut (RPP), scientifically known as Arachis glabrata, is a warm-season perennial legume gaining popularity as a forage crop and groundcover. It is closely related to the common edible peanut, Arachis hypogaea.
Considerations for Pets
- As a forage crop, rhizoma peanut is often grown in hay fields. While generally considered safe, hay can sometimes contain insects or molds that could be harmful if ingested in large quantities by pets.
Taxonomy and Nomenclature
- Scientific Name: Arachis glabrata Benth.
- Common Names: Rhizoma peanut, rhizoma perennial peanut, perennial forage peanut, creeping forage peanut, golden glory, ornamental peanut grass, Florida's alfalfa (due to its superior forage quality), amendoim-bravo, mendoim-do-campo-baixo.
- Synonyms: Arachis hagenbeckii Harms
Distribution and Habitat
- Native to South America.
- Well-adapted to subtropical and tropical environments, particularly in the coastal plain region of the United States (e.g., Florida, Louisiana).
- Often found in well-drained soils.
Ecological Role
- Can be planted in strips within bahiagrass pastures to create a grass-legume mixture, offering a viable approach to pasture management.
- Studies are ongoing to determine the best strategies for weed control when planting rhizoma peanut in existing bahiagrass pastures.
- Can tolerate up to 30% shade, indicating its adaptability to different light conditions.
Morphological Characteristics and Growth Habits
- A perennial legume with high dry matter (DM) yield.
- Characterized by long-term persistence and high nutritive value.
- Cultivars such as Florigraze and Arbrook have been selected for their high yield and quality.
- Exhibits a warm-season growth habit.
Cultivars
- Florigraze: A commonly grown cultivar known for its high yield and quality.
- Arbrook: Released in 1985, selected from plots of an accession introduced from Paraguay in 1959, known for high yield and quality.
Interactions with Other Organisms
- Can be grown in association with grasses like bahiagrass.
- Susceptible to Peanut mottle.
