Mammillaria bombycina 'Silken Pincushion'

$ 9.00
Size: 4"

An absolute stunner of a specimen, Mammillaria bombycina ‘Silken Pincushion’ features a typically solitary, columnar stem with a rich bluish green base hue. Most intriguing, however, is the arrangements of the tubercles and spines. When viewed from the side, the white and rusty red spines form a starburst pattern around each tubercle. While this is incredible on its own, the real magic happens when the stem is viewed from above – it is from this angle that the natural swirling pattern formed by the tubercles, a real-life example of the Fibonacci sequence at work, is made visible!

When provided with the bright to direct sunlight it prefers, ‘Silken Pincushion’ will also produce a ring of light pink to deep magenta blooms during the spring months. To keep this variety thriving, and to encourage the stems to reach their full 8 inch height, be sure to utilize a porous soil mixture within a well-draining pot and water in accordance with a thorough yet infrequent routine, such as the ‘soak and dry’ method.

During the winter months, it is important to protect ‘Silken Pincushion’ from freezing temperatures – though a period of exposure to cooler weather in the 45-55 degree range will actually encourage more prolific blooms in the springtime!


Plant sizing is based on the diameter of the nursery pot (2", 2.5", 3", 4" etc), not the plant itself. Plants may be slightly larger or smaller than the pot they are grow in depending on availability or time of year. While we do our best to ship plants as similar to those pictured as possible, please keep in mind that all plants are unique from one to the next, and display color, shape, and growth variation based on current environment, time of year, and other contributing factors. Please note that we ship our plants as dry as possible in the fall and winter months to prevent root rot or freezing. They will plump back up after planting!
