How to grow a pincushion cactus

Coryphantha bumamma
The symmetrical and rugged beauty of the pincushion cacti are appreciated by many and if you are one those and have never owned one, you will be happy to find out that they are amongst the easiest of houseplants to keep!  Especially if you have sunny windows.  If they are well kept they should bloom for you.  Cacti blooms are usually showy and colorful. This one is usually a late summer to fall bloomer with reddish-yellow flowers.

The Coryphantha bumamma, (really), is considered part of group called pincushion cacti, for obvious reasons. It's common name is "Starry Ball".  This one can grow up to 6" (15cm) high.  Of course, cacti prefer a desert setting and the "Starry ball" is naturally found in Mexico. The cacti family is so interesting and varied. As you look at them and think about these unusual, sometimes comical living things, it just makes you wonder.

I happened to see this very healthy and beautiful specimen when visiting my favorite florist in McLean, Virginia.  They are happy to send plants or flowers almost anywhere in the world for you.  Flowers and Plants Etc.

Care Instructions---  
  • Direct sun. Cacti will tolerate lower light for awhile but I recommend as much direct sun indoors as possible.
  • Water when dry about 1/2" or more below the soil surface. This can be difficult and maybe painful to gauge. There are water meters available on the market which can be very helpful for some and are highly recommended for cacti growing.
  • Cacti do like to dry out but not to stay completely dried out for long. 
  • Fertilize every few months or so.  They are slow growers so that should suffice.
  • There are cacti and succulent soil mixes on the market but you can also mix half sand and half potting soil when repotting.
  • The desert temperatures have an extreme range and if your home is cooler at night than it is during the day, that is best.  A sunny windowsill is often the very best place indoors for them.
