can ibuy a giant cactus for my home?

It depends what you mean by giant. You can certainly get some very large ones from specialised cactus nurseries, and the British Cactus and Succulent Society forum has a lot of advice. But large for a cactus could be a couple of feet in which case it would be very old and very costly. Indoors is fine as long as there is plenty of light. Don't buy on ebay, many of these are taken from the wild, and generally are illegal since many are protected.

Hi Weeruby,

Where abouts are you? UK? We have a couplle of large cactus I'm selling before the spring (emigrating).

One is nearly 6 feet tall and a prolifick producer of extra stems. And we have a twin pair just over three feet.

I'll try and take some pictures for you.
