This fun little cactus is a unique plant that blooms and will eventually form tiny mounds.  Mammillaria duwei is a small growing but easily flowering species that will make clumps given the best conditions.


  • Flowers: Yellowish/cream to light yellow, about 20 mm long and in diameter.
  • Blooming season: Flowers readily, and for a long period from spring to the early summer.
  • Hardiness: Reputedly sensitive to frost, but less so if kept on the dry side prior to, and during, cold weather (hardy to -5° C for short periods). However, warmth throughout the year will increase the grower's success (minimum 5° to 8°C during the rest season).
  • Exposition: Outside bright sun, filtered sunlight, or afternoon shade, inside it needs bright light and some direct sun. Subject to sunburn if exposed to direct sun for too long. Tends to bronze in strong light, which encourages flowering and heavy wool and spine production.

This unique cactus is a great addition to your collection. Shop Planet Desert for this cactus and more!

Mammillaria duque & Ferocactus macrodiscus

This was the first time I was anxious about my order. The weather was extremely hot, the box was hot and the plants were hot. All in all, the plants arrived in good condition and now hope to get many years of enjoyment watching them grow and bloom.

Prolific Blooms Despite its Small Size

Highly recommend. Mine is a small cactus, only 1 1/4" across, but bigger than it was last year when it arrived. I was pleasantly surprised when it bloomed last April and it is in bloom again, nine small, creamy yellow flowers or buds in a halo on its top. This little guy is beautiful even when it's not in bloom because its spines are delicate, star-like, and lie flat against the stem, so they won't poke you when handled.
