Description: Mammillaria guelzowiana is a soft small solitary or clustering cactus, with the stems obscured by spines, but this specie tends to impress because of its bright magenta flower about 6 cm in diameter - very large for a Mammillaria!
Blooming season: June/July

Cultivation and Propagation: It is one of the more difficult species to grow long enough to produce clumps, but if grown correctly, it will reward the grower with generous displays of purple flowers; plants should be allowed to become crowded in their pot. Keep in shallow pots.
Watering Needs: Need regular water but do not water again until dry as it is specially sensitive to over watering. Also, it is a species that is dormant in the winter and require very little water (maybe even none) during the cold months.
Frost Tolerance: Light frost protection required. Minimum of 5ºC for safe growing (but hardy up to -5°C or less.)
Sun Exposure: High levels of light are needed to flower and for good spine development. Can be sunburned if moved from shade/greenhouse into full sun too quickly. During the spring it may be able to take full sun until the heat arrives at the end of spring. In an area that has hot afternoon sun, it may be able to take full morning sun, but requires afternoon shade or afternoon light shade.

Excited to Grow and Bloom

Planet Desert continues to exceed my expectations! I also cannot wait to see this beauty come spring/ summer when it will bloom. As always, care in packaging and shipping keeps plants happy and healthy, even when the delivery service is delayed. Finally, I also love the rewards program for future purchases.

I have been buying my cactus from Planet Desert for several years now and not once have I ever been let down or sent a less than desirable specimen. Every plant is in excellent health and shipped with intentions of preserving the plant in that exact condition. My recent order of Mammillaria Guelzowiana was no exception to the rule. Muchas Gracias Planet Desert!
