The large flower star cactus belongs to the Asclepiadaceae family, a perennial succulent herb, also known as the large flower rhino horn, native to South Africa. The plant has many branches at the base, forming a clump and growing upright. It has a succulent stem, gray-green in color, thick, with four-angled ridges, toothed projections, and short soft hairs on the edges. The stem is about 20-30 cm in height and 3-4 cm in diameter. The flowering period is approximately from June to September. The flowers grow from the base of the tender stems, with ovate flower buds that are like small eggs, splitting into five petals that resemble a starfish. Some people also call it the "sea star flower." The flowers are large, with a diameter of about 15-20 cm, having purple-red filaments inside the petals and dense purple-brown fine hairs on the edges. The flowers have a slightly rotten smell, not very pleasant, hence the name "smelly meat flower," which can only attract flies to help with pollination.
The large flower star cactus prefers a warm and dry climate, is robust in nature, drought-resistant, and enjoys fertile, well-drained sandy soil. The optimal growth temperature is 16-25°C. In winter, it's best to place it outdoors to receive ample sunlight, with temperatures above 10°C to prevent dormancy due to low temperatures. It should be kept warm, moved indoors or into a greenhouse, and watering should be controlled to avoid frost damage to the succulent stems due to low temperatures, which could affect growth and appearance. In the summer高温, the plant may enter a semi-dormant state. To prevent sunburn and red spots caused by direct sunlight, it can be placed in a slightly shaded area, with enhanced ventilation and heat dissipation, controlled watering, and attention to moisture control to prevent rotting due to humidity. During the plum rain season and typhoon season, it should be protected from prolonged rain to prevent root rot.
Since the plant grows rapidly, it can be repotted every spring using organic compost, mixed with some珍珠石, vermiculite, or expanded slate to increase drainage. Every 15-20 days, a liquid fertilizer for leafy plants can be applied to increase fertility.
Propagation methods include division, cutting, and seeding. Division is usually done during repotting; cuttings can be done at any time with the right temperature, using branches over one year old, about 10 cm long, and planted after the wound is dried. After seeding, the seedlings grow slowly and take 4-5 years to bloom, which is a long wait, but it's worth a try for those with patience.
When the large flower star cactus is not flowering, it looks like other succulents. It is suitable for placement in a bright indoor area or as an accent in a rockery or bonsai. However, the smell of decay and the swarming flies when it flowers might scare many people.
