About Kermes oak
Quercus pseudococcifera, commonly known as false kermes oak, is an evergreen shrub or small tree native to the Mediterranean region, valued for its dense and resilient foliage. It features small, leathery, spiny, dark green leaves, giving it a robust and ornamental appearance. It is ideal for low-maintenance gardens, xeriscaping, defensive hedges, or as a standalone specimen in Mediterranean landscapes, providing structure and drought resistance.

Care tips
It requires full sun exposure for optimal growth and good fruiting. It is extremely drought-tolerant once established, so watering should be sparse, especially in summer. It prefers well-drained soils, even poor and calcareous ones, and does not tolerate waterlogging. A common mistake is overwatering, which can lead to root rot.
