The Tephrocactus Alexanderi’s stem is what makes it special. The flat and oval stems are green or bluish-green. These pads have tiny, hair-like spines. They’re all connected, like a chain, giving the cactus a cool pattern. Besides its unique appearance, the stem is good at soaking up water when it rains and storing it for dry times.

Tephrocactus Alexanderi has pretty flowers that add color to its unique appearance. The flowers are small and appear on the edges of the flat pads. These flowers come in different colors, like pink, red, orange, or yellow, making the cactus look even more charming. When it’s flowering in late spring to early summer, it brings a cheerful and lively vibe to the cactus. Although considered a short-relative period, it is enjoyable for those who appreciate its beauty.

Tephrocactus Alexanderi has roots near the surface of the soil. These shallow roots are spread out to grab water from a big area. When growing this cactus in the ground or pots, it’s important not to make the roots too wet, which can be bad for the cactus. Even though the roots are not deep, they still help the cactus stay put in the soil, especially when it gets windy. So, caring for the roots is essential for keeping this cactus healthy and happy.

Care Guide

Light: Tephrocactus Alexanderi thrives in bright, indirect sunlight. Provide at least 6-8 hours of sunlight per day. Place the cactus away from direct sunlight for a long time, as it may damage the delicate stems.

Temperature: This cactus prefers warm temperatures. Keep it in an environment where temperatures range between 70-100°F (21-38°C) during the day and not below 50°F (10°C) at night.

Soil: Use a well-draining cactus mix or create a mix by combining regular potting soil with sand or perlite.

Watering: Tephrocactus Alexanderi should be watered sparingly. Check the soil’s dryness between waterings. Water deeply when you do water, but be sure to water until the water flows out of the drainage hole. Reduce watering in the winter months and more often in growing seasons. However, you should set your watering timetable because of different growing conditions.

Humidity: Tephrocactus Alexanderi can tolerate low humidity levels. However, avoiding high humidity is essential, as it may lead to fungal issues.

Fertilization: Feed the cactus with a diluted, balanced cactus fertilizer in the growing season (spring and summer) every 4-6 weeks. Please remember to say NO to fertilizer in winter months.


You can make more Tephrocactus Alexanderi plants in two ways: using seeds or cuttings. With seeds, collect them, put them in the soil, and keep it a bit wet until they grow, which takes a few weeks. Pick a healthy piece for cuttings, let it dry for a day, then plant it in a bit of deep soil. Use root stuff and put it in a warm, bright spot but not too sunny. Roots should grow in a few weeks to a couple of months. Whichever way you choose, be patient and take good care of more cool cacti!


To sum it up, Tephrocactus Alexanderi is a cool plant you can grow from seeds or cuttings. Just give it good soil and sunlight, and don’t water too much. Be patient, and soon you’ll have more of these awesome cacti to enjoy! Happy planting!

  1. Love succulents, I’ve been playing around with them for the last couple of year, reading up on them and propagating them, my main aim is to be patient with them, and trying to learn their names, would you have pictures of them with their names? So I could put a name on my pots?
