Huanyu, also known as Fenestraria rhopalophylla, is a general term for species in the genus (also called the stone plant genus), and is described as a "living stone." Because of its unique form and colorful appearance, it has become a very popular ornamental plant. To adapt to its environment, it evolved from a dicotyledonous plant into a typical succulent spherical-leaf plant, surviving on the meager moisture stored in the water-storage tissue within its cortex. Its top surface is called the "window." Inside the window, chlorophyll carries out photosynthesis. The top is slightly flat, with a slit in the middle. In autumn, plants 3 to 4 years old produce yellow, white or pink flowers from this slit.

Morphological characteristics

Perennial small succulent plant. The stem is very short and often invisible. The modified leaves are thick and fleshy, with two opposite leaves joined to form an inverted cone. There are many varieties, each with its own characteristics. In autumn, 3-4 year old Huanyu plants produce yellow, white, pink and other colored flowers from the slit between the opposite leaves, mostly opening in the afternoon, closing in the evening, and opening again the following afternoon. A single flower can stay open for 7-10 days. When in bloom, the flowers cover almost the entire plant, making it very delicate and beautiful. After the flowers fade, fruits form, and very tiny seeds can be harvested. Huanyu is shaped like a colorful stone, rich in color, small and exquisite, and enjoys the reputation of being a "living stone."

The entire plant is fleshy, with a very short stem. The fleshy leaves are joined in opposite pairs, shaped like an inverted cone. They come in colors such as pale grayish brown, bluish gray, grayish green and grayish brown. The top is nearly ovate, flat or raised, with dendritic depressions, and semi-transparent. Flowers emerge from a small slit in the middle of the top, yellow or white. A plant usually produces only 1 flower (rarely 2-3), opening in the afternoon, closing in the evening, and lasting 4-6 days, with a flower diameter of 3-5 cm. After flowering, it readily sets fruit and seed.

Growing environment

It likes sunlight, and the optimum growing temperature is 20°C-24°C. In spring and autumn, it is best placed on a south-facing balcony or windowsill for cultivation. This is precisely its peak growing period, and it should be watered once every 3-5 days to promote growth and flowering. The growth pattern of Huanyu is that it begins to grow between March and April, pauses growth during the hot season, enters a summer dormancy period, then continues to grow and flower after the weather cools in autumn, and enters the overwintering period after the flowers fade.

Place of origin

It is native to the extremely arid, rain-scarce desert gravel areas of Cape Province, South Africa, with annual rainfall below 250 mm, an average winter temperature of 10°C, and summer temperatures of 20-25°C. It goes dormant in the dry season, and the spherical body gradually shrinks and buries itself in the soil, leaving only the top surface exposed above the ground like gravel. This kind of "mimicry" serves to prevent birds and animals from eating it.

Propagation

It is mostly propagated by sowing, and autumn sowing is preferable. Seedlings can emerge 10-20 days after sowing. During the seedling stage, excessive moisture should be avoided. During high summer temperatures, it goes dormant or semi-dormant, so it should be slightly shaded and watering should be restricted.
