Ferraria schaeferi, commonly known as the Spider Iris, is a deciduous perennial bulb native to the arid and semi-arid regions of southwest Namibia and northwest South Africa. It typically grows to a height of 1 foot (0.3 meters) and a width of 0.5-1 feet (0.2-0.3 meters). The plant is adapted to survive in harsh environments with hot, dry conditions and is often found in sandy or rocky soils.

The Spider Iris is notable for its unique and striking yellow to brownish-yellow flowers that resemble spiders, which appear in the spring. The blooms are often speckled or marked with contrasting colors, adding to their exotic appearance. The plant is relatively low maintenance and drought-tolerant, making it suitable for xeriscaping and rock gardens. It is also used in borders and as an accent plant in succulent collections. In cultivation, it requires full sun or part shade and thrives in well-draining soils. While it is generally pest-free, it can be susceptible to rot if overwatered. The Spider Iris is not known for being invasive and is considered safe for cultivation outside its native range.CC BY-SA 4.0
