Mammillaria compressa
Mother of Hundreds!
When I first saw a mass planting of this Mammillaria at the Huntington Botanical Gardens I fell in love with the species and said I had to grow it. I went home and ordered seed immediately and after several years of growth I have more plants than I personally need. This Mammillaria starts out developing a solitary head that is about 4" in diameter and 8" tall, eventually clustering and making a mounding colony up to 3' in diameter. Each body is covered in angular tubercles that have 4 to 6 bristly, radial spines on the tip of each tubercle. The axils or areas between the tubercles normally display wool and bristles, but the amount of wool varies by seedling . In late winter and spring light to dark pink flowers occur in rings near the upper third of the plant bodies.
Images shown were taken at the Huntington Botanical Garden. Notice the variation in spination and axillary wool development.
