Queen of the night
Queen of the night is a resilient columnar cactus often recognized for its ribbed, green stems that can tower up to 6 meters tall. Its nocturnal white flowers bloom briefly, inviting pollination, while the fleshy, spiny exterior is adapted to arid environments by retaining moisture and deterring herbivores. Thriving in rocky soils, queen of the night's root system anchors it against strong winds.
