About Orchard grass
Dactylis smithii, known as kalliokoiranheinä, is a perennial grass from the Poaceae family, characterized by its lanceolate leaves and dense panicle inflorescences. It is a robust and compact-growing plant, ideal for rock gardens or as ground cover in full sun areas, providing interesting texture and a fresh green color. Its resilience to adverse conditions makes it an excellent choice for low-maintenance landscapes.
Care tips
It requires full sun for optimal growth and abundant flowering; it tolerates partial shade but with less vigor. Watering should be moderate, allowing the substrate to dry out slightly between waterings, as it is a drought-tolerant species once established. It prefers well-drained soils, even poor or rocky ones, adapting well to a wide pH range. Avoid overwatering and waterlogged soils, as this can lead to root rot.
