The lipstick plant (Aeschynanthus radicans) is a tropical plant native to Southeast Asia. It is known for its vibrant, tube-shaped flowers that resemble tubes of lipstick, hence its common name. This plant is typically grown indoors as a houseplant, where it can thrive in bright, indirect light and humid conditions. It requires regular watering and well-draining soil to prevent root rot. With proper care, the lipstick plant can produce clusters of blooms that add a splash of color to any indoor space.
