Posted this in the Cactus Succulents section, but Dracena is a house plant as well. So thought I would post my creation here for your enjoyment. :)

I can't decide if I like this or not. The succulents are Zebrina, then of course three Dracena Plants. I really wanted smaller pebbles, but could not find any. Can't decide if I like the white pebbles or not. Perhaps, a more natural color would have been better, but I thought it would make the white stripes on the Zebrina pop. Sorry, it's a cloudy dreary day here, and even with the flash on the cell phone, I couldn't get a brighter pic. The battery for my camera is charging. I will try a better picture as soon as it charges. But here ya go...still haven't got a figurine for in front of the Dracena's. The Dracena's have beautiful burgundy leaves, also not being picked up because of the dreary day.

Very nice Alan! I think the white pebbles look nice and I love the container. I am curious as to how you will keep those Dracaena marginata's to a manageable size. They are grown as landscape plants here in some parts of Florida and they get large. They grow so fast that I'd think it would require constant root pruning to keep them small but they sure look nice with those Haworthia plants.

Here they grow medium-slow. Perhaps because of lack of humidity??? But I suspect I will have to replace them in two years tops. I really wanted more of a succulent type plant for the main tree in the bonsai. Perhaps a jade or something like that, but could not find a nice single trunk specimen, that I could prune up into a nice tree. All of them were several plants in one pot. So, I can keep a watch out for that plant to replace the Dracaena , and put the Dracaena in a different pot when the time comes. I'll also put something hanging over the edge, as Hetty suggested, at that time. I brought it in tonight...we are suppose to get very close to freezing tonight

Alan,
I like what you did. I have an idea. What if you planted the Dracaena in it's own small pots then put inside the larger pot and cover with the stones! That way you can easily remove and prune what ever you wanted to then put back. Also the Dracaena I think needs more peaty soil and the Haworthia's like a fast draining type.

Slush, if I would have left them in the pots they came in, I would not have been able to fit them so close together in the big pot. Would have been a great idea, if I had a bigger bonsai pot

This bonsai is outdoors, not indoors. It will remain there all year long. Temps of 115 degrees in the summer will promote rapid drying too ;) But It will be shaded, and close to the north side of the house where it is cooler. And it will be watered twice a day in the summer. In the morning before I go to work (4:30AM) and at 1:30PM, when I get home from work. Thanks for the input.
