Gardeners' Notes:

Positive diamonddi On Apr 7, 2010, diamonddi from hollister, CA (Zone 9a) wrote:

I grow this cactus in strawberry pots and also have them in a hanging basket. I use the type of basket liner that is made of soft thick coconut like fibers so I can cut a small opening in the liner and stick a new little baby cactus in the side. Especially, since these plants multiply very quickly. I highly recommend this cactus as they are so easy to grow. I tend to kill potted plants with kindness and these babies even thrive throughout my overwatering.

Neutral Xenomorf On Mar 7, 2005, Xenomorf from Valley of the Sun, AZ (Zone 9b) wrote:

The subspecies 'echinaria' is different in that it has 2-3 dark central spines. Unlike the subspecies 'elongata' which has none or very short central spines if any.
The 'Copper King' cultivar has copper colored spines on top.

Other valid synonyms are: Cactus elongatus, Cactus intertextus, Krainzia elongata & Mammillaria tenuis var. media

This cactus is easy to grow. Needing only occasional water and minimal fertilizing these are perfect for indoor gardeners. They can take indirect light or even a bit of shade and grow well under lights.
