Pachycereus Pecten Aboriginum
Pachycereus Pecten Aboriginum is an impressive columnar cactus native to Mexico, capable of reaching up to 15 meters in height in its natural habitat.
Its scientific name, meaning “comb of the natives,” comes from its fruits covered with rigid spines traditionally used as combs by certain local populations. Its massive deep green stems bear 10 to 12 well-defined ribs lined with woolly areoles and robust spines. With age, it forms true forests of columns, reminiscent of iconic desert landscapes.
In spring, Pachycereus Pecten Aboriginum displays tubular white flowers, slightly pinkish on the outside, which open at night to attract nocturnal pollinators. The fruits that follow, yellow and spiny, are edible and sweet, consumed fresh or made into jams in the regions where it grows.
It thrives in arid plains, rocky hills, and limestone soils, often near warm coastal zones. These environments, subjected to extreme temperatures and rare but intense rains, have shaped a highly resilient cactus.
🌞 Direct sun: minimum 6 to 8 hours per day.
🌤️ Light protection may be provided for young plants during extreme heatwaves to prevent burns.
Lack of sunlight causes elongation and general weakening.
🌱 Spring / summer: water every 4 to 5 weeks, allowing the substrate to dry completely.
🍂 Autumn / winter: in dry warm outdoor conditions water very sparingly; in pots and cool climates stop watering.
⚡ Absolutely avoid excess moisture, which promotes root rot.
🌞 Ideal temperature: 22 to 35°C.
❄️ Minimum tolerated: around 5°C, only if the substrate is dry.
🏠 In pots, bring indoors once night temperatures consistently fall below 10°C.
🪨 Recommended mix: cactus soil + 40 to 50% minerals such as perlite or pozzolana.
A deep and heavy pot is recommended to stabilize this massive cactus.
🌸 Season: spring, sometimes summer.
🎨 Color: pure white with pinkish exterior, yellow center.
🕑 Duration: 1 to 2 nights per flower.
💡 To encourage flowering: full sun, dry winter rest, and cactus fertilizer in spring.
