Genus:Alternanthera

Species:dentata

Family:Amaranthaceae

Alternanthera dentata is a tropical perennial often cultivated as an annual, celebrated for its vibrant foliage that varies from burgundy to purple. The genus name derives from the Latin terms "alternans," which means alternating, and "anthera," referring to the anther. In this genus, the anthers are typically barren and arranged alternately. The specific epithet "dentata" translates to "toothed," highlighting the serrated edges of its leaves. This plant thrives in rich, consistently moist, and well-drained soil, exhibiting its most brilliant leaf color when exposed to full sunlight. To encourage a bushier growth habit, pinch back the tips of the stems.

**Season:** Spring through frost.
