Quick facts

About Long-leaf crabgrass

Digitaria longiflora, commonly known as Indian crabgrass, is a low-growing annual grass with a creeping habit, forming dense mats. Its leaves are narrow and pale green, and it produces slender, spiky inflorescences. While often considered a weed in lawns, its resilience and ground-covering ability make it interesting for low-maintenance revegetation projects in warm areas.

Native range

Tropical and subtropical Asia, and Australia

Care tips

This species thrives in full sun exposure and well-drained soils, although it is quite tolerant of various soil conditions. Watering should be moderate, allowing the substrate to dry out between waterings, as it tolerates drought well once established. Avoid excessive moisture, which can lead to fungal diseases. A common mistake is attempting to grow it in dense shade, where its growth will be weak.
