This species possesses remarkable adaptability and can endure various living environments, withstanding temperature extremes ranging from 5℉(-15°C) to 104℉(40°C).

The blue-gray leaves will turn into shades of pink, jelly yellow, or lavender, occasionally accompanied by rare bloody spots. This characteristic arises from an ideal balance of sunlight and temperature. That makes Graptopetalum paraguayense look like Graptopetalum 'Purple Delight', another species of the same genus.

Cold Hardy Temperature: -4℉(-20℃ )

Orostachys succulents, belonging to the family Crassulaceae, are a testament to nature's beauty and resilience with their unique patterns and shapes. These biennial or perennial herbs are native to subtropical and temperate regions across China, Japan, Korea, Mongolia, and Russia. Some even thrive in extreme conditions, growing on the roofs of tile houses and in mountainous terrains. During summer and autumn, these succulents produce many seeds after flowering. Once the seeds mature, the mother plant dies, but the seeds quickly reproduce in the following spring, allowing for a continuous cycle of growth and beauty.

Due to hybridization, Orostachys succulents have evolved into several ornamental potted plants, including Orostachys chanetii, Orostachys japonica, Orostachys iwarenge, Orostachys spinosa, etc. Orostachys succulents are incredibly hardy and can tolerate temperatures ranging from -4℉(-20℃) to 104℉(40℃), making them ideal for any space.

The stems of these buds emerge from the mother plant crazily like plant vines and extend outward, imparting an alluring and distinctive appearance.

Growing Orostachys boehmeri in a flower pot of appropriate height is highly recommended. The plant's side buds should be allowed to overflow from the mouth of the pot and hang outside the edge, creating an elegant and beautiful display. Orostachys boehmeri grows faster during spring, summer, and autumn, and its leaves may shrink slightly in winter. Nevertheless, the plant has strong cold resistance and can survive temperatures as low as -4℉(-20℃).
