Populations of this species are relatively numerous and abundant. It grows in dry rocky places in the open or mainly in xerophyllous vegetation. Despite the great abundance and diversity of cacti in Mexico, Mammillaria magnimamma is one of the few cacti species that has colonized barren lava fields. In parts of its range the species is threatened by local extraction for ornamental plant trade and by the expansion of urbanized areas.

Mammillaria magnimamma is a perennial stem succulent solitary at first, later branching basally or dichotomously to form large mounds up to 50 cm in diameter or more barely rising above ground level.

This species is very variable and has received many names. In particular the spines are of variable shape and length, occasionally they are very long msmmillaria to 5 cm long. Flattened globose to globose, grey-green to dark blue-green, cm in diameter and up to 30 cm tall.

Conic-pyramidal as long or longer than broad, about 10 mm tall, firm, four-sided but not sharply angled, with latex, flowering axils with dense white wool, especially when young.

Dirty white, creamy-yellow or tinged brown with reddish midveins, to deep purplish pink, mm wide and long and in diameter.

Volume 63,page. Downloaded on 01 February Mammillaria magnimamma is easy to cultivate, and makes an interesting specimens. Over time it will produce large clumps. It grows by producing offsets, and also by dichotomously dividing and doesn’t require any special treatment, but needs as much light as possible without burning the plant, to keep the stems compact. It is a small growing, but easily flowering species.

It takes several years to offset, but once it starts it can fill a 40 cm pot in a few years given the best conditions. Use a an open and free draining mineral compost with little organic matter peat, humus that allows therefore roots to breath as it is rot prone.

Repotting every years. As it is especially prone to mammilaria under-pot in a smaller container filled with very porous compost. Use shallow pot with good drainage. It likes a winter’s rest and should be kept almost completely dry during the winter months, If the soil is allowed to be dry for too long root loss could follow but equally the same result magnmiamma occur if the plants are both wet and cold. From March onwards the plant will begin to grow and watering should be increased gradually until late May when the magnimamka should be in full growth.

Water regularly during the summer so long as the plant pot is allowed to drain and not sit in a tray of water. During hot weather you may need to water the plants more frequently so long as the plant is actively growing.

From late September watering should be reduced to force the plant to go in mammillarai a state of semi dormancy, by October you should be back in to the winter watering regime. Mammiloaria dry with ample airflow in winter.

In the rest period no high atmospheric humidity!! Care must be taken with watering as they tends to become swollen and untidy in growth habit if given too much water and shade.

Feeding may not be necessary at all if the compost is fresh then, feed in summer only if magnimmamma plant hasn’t been repotted recently.

Do not feed the plants from September onwards as this can cause lush growth which magniimamma be fatal during the darker cold months. Some magnimwmma throughout the year will increase mammillsria grower’s success. Need full sun avoiding only the harshest summer sun, if kept too dark they may become overly lush and greener and could be prone to rotting due to over watering. Tends to bronze in strong light, which encourages flowering and heavy wool and spine production.


It is an excellent plant for container growing. It look fine in a cold greenhouse and frame. It may be attractive to a variety of insects, but plants in good condition should be nearly pest-free, particularly if they are grown in a mineral potting-mix, with good exposure and ventilation. Nonetheless, there are several pests to watch for: Sensitive to red spider mite.

Overhead watering is helpful in controlling mites. Occasionally mealy bugs they develop aerial into the new growth among the mammillarla with disfiguring results, but the worst types develop underground on the roots and are invisible except by their effects.

Scales are rarely a problem. If they are not, fungicides won’t help all that much. Direct sow after last frost or cuttings. The seedlings should not be disturbed until they are well rooted, after which they can be planted separately in small pots.

Cuttings of healthy shoots can be taken in the spring and summer. Cut the stem with a sharp, sterile knife, leave the mammullaria in a warm, dry place for a week or weeks depending on how thick the cutting is until a callus forms over the wound.

Mammillaria magnimamma Haw.

mangimamma Once the callus forms, the cutting may be inserted in a container filled with firmed cactus potting mix topped with a surface layer of coarse grit. They should be placed in the coarse grit only; this prevents the cut end from becoming too wet and allows the roots to penetrate the rich compost underneath.

The cuttings should root in 2 to 6 weeks. Mammillaria magnimamma Photo by: Schelle Neomammillaria magnimamma Haw. Has blue-green body, dirty cream to reddish flower, and no central spines. It is very variable. Send a photo of this plant. The gallery now contains thousands of pictures, however it is possible to do even more.

We are, of course, seeking photos of species not yet shown in the gallery but not only that, we are also looking for better pictures than those already present. Back to Mammillaria index.
