Mammillaria compressa
Horticultural Data | Shipping & Availability | Top
Mammillaria compressa originates from the central Mexican states of Hidalgo, Queretaro, Guanajuato, Tamaulipas, Nuevo León and San Luis Potosi. This plant works well in cactus gardens as a low spreading medium-scale ground cover. Mammillaria compressa can be grown in containers as well and will quickly offset to fill them. This is an easy Mammillaria to grow, resistant to rot and erratic watering. Mammillaria compressa has sharp spines and should be located away from foot traffic. Mammilliaria compressa is easily propagated by dividing offsets or can be grown from seed. Fruit should be significantly overripe before harvesting seeds. From seed it germinates best in vitro in gelatin or agar.
This is a fast growing Mammillarias species. It is a grey-green globular cactus which spreads by division to form small colonies. Underground, Mammillaria compressa grows a long club-shaped caudex root to store water. Above ground, Mamlillaria compressa is covered in angular tubercules that have 4 to 6 bristly, radial ½” – 1″ spines. The axils on this plant often display wool and bristles, the amount of wool varies by seedling. In early spring it flowers with ¼ to ½” flowers of carmine red to pink, which form a ring around the crown of each cactus. Growth is quicker in richer well-draining soils. Its tiny fruit are remarkably delicious — tasting like strawberries.
