When you say you're going to use 8" pots, do you mean a grouping in each pot or just one per pot? Crypts are small plants. I generally grow them in 4-5" pots, maybe 6" max. You could do a dish garden grouping of 3 in an 8", but in that case it would be better to use a shallow pot, like a bulb pan.

They aren't really succulents and don't like to dry out much. They don't like to be out in full sun either, but indoors in a bright window should be fine. Try Michael's Bromeliads or Tropiflora for mail order. Both are online.

Thanks for the information!

I thought they were succulents because they were listed in a page about them...

Also, thanks for the sizing. I have one large window but if necessary, I can move the crypts away from it a little. The can hang out with the snake plant I just bought.

I'll look at those vendors. Thank you!
