What are and how do I obtain miniature cacti?

November 21, 2009 12:11 PM

Are miniature cacti just younger plants or do they have their own name or classification? Awhile ago I saw some tiny (~1 in. apiece) cacti for sale in a big box garden/home supply store, but am not having luck finding them online (getting a lot of hits for dollhouse miniatures, etc). I would like to buy some but know neither the right terminology to use, nor where I'd buy them. I've already browsed several online cacti stores w/o success. Thanks for your help tracking this down!

"Indoor cacti" is the phrase you're looking for, I believe. Looks like Cactus Joe will ship you some.

You may also be interested in the miniature cacti available from ThinkGeek. They're a bit smaller than one inch, though.

Best answer: They're all over in hardware stores here in AZ - Lowe's, Home Depot. I think I've seen them in hardware stores elsewhere in the country as well (whoo $1.99 young plants!). They're just the offshoots of older plants of the same time, and are generally available in variety packs. I haven't seen them labeled very accurately.

Many cacti also grow from seeds and Home Depot has mini greenhouses for various cacti usually available in the spring.

There's a cactus nursery near where I live called B & B Cactus Farms. They have a wide selection (and pretty cacti!) and ship anywhere in the US.

Response by poster: Smaller is better, thanks MaxK and carsonb.

So, bookdragoness, if they're just offshoots will they grow larger with time?

Actually, it's more like they grow larger with water. My friend mists hers once every week or so and it isn't appreciably larger than when I first saw it two years ago. It was only when I started watering my aloe often that it grew another foot and put off offshoots (over a two-year period).

Someone gave me a very tiny cactus from Wal-mart a few years back. It grew to be a couple feet high with frequent watering and lots of sunshine. I finally tossed it out after accidentally brushing up against the needles. Ugh. (And by the way, the ones you might see in Wal-mart with the impossibly large colorful flowers on top are fake - the flowers are glued on.)

Best answer: You'll need to find out the botanic name to determine the size. As pointed out above, they are offshoots, and could grow into something huge. I wouldn't subscribe to the idea that restricting water will keep them small; it may slow them to a degree but a plant's eventual size is determined by genetics. While many succulents can remain dormant for a long time, eventually they do have to be watered and will use that opportunity to grow. If you want something that will stay tiny for a very long time, look into lithops. They are small, spineless, and grow very slowly. Care is somewhat exacting but minimal- they will die if overwatered.

Response by poster: Thank you, oneirodynia. Sounds like a great place to start.

(This is for a gift idea, for what it's worth--I've long been known to kill my own plants, even those that don't need a lot of water).
