    That depends on the growing conditions. I have some that grow around the
corner of my house and they are 180 on the west side and 360 on the south
side. I have some who start out 180 and then go 360.

With leaves only growing on one side of the plant? Are you sure someone 
isn't just using the leaves on the other side? :-)

Funny this came up now...I just had to use some on a bad scalding burn I 
got on my hand from some very fresh coffee...

    No, I was using a short cut I thought you would get... some with leaves
growing 0` and 180`, some growing with leaves pointing all around. I also
seem to remember (it's too cold to go look) that the closer they are
together, the more they grow in just two directions.

It now looks even better, just put a lot of them on a nice isosurface
landscape, add radiosity, area light, ... and wait a loooooong time till
it's finished. :-)

That's partly from the pigmentation on the insides of the leaves; when I
created it, I was basing it on aloe, and I seem to have nailed it right
on the head.

I have since thought of a scene to add this to, and I'll be striving for
something more yucca-like next time I work on it, but if I get bored
enough, I may try making a more convincing aloe as well. :)

There IS radiosity, it's just not terribly precise because of speed and
memory considerations. For that matter, I think I turned the area light
on too. And if it hadn't been taking so damn long, it'd be sitting on a
granite function instead of a plane.. so that's almost three out of
four. Not too bad, eh?

As for using a lot of them.. it's in the cards, but I gotta finish
designing one first. ^^;

Oh, I see now...just been programming too much lately...I failed Grammar 
II last year, ok? :-)
If you had said y*rand()*360, I would have understood...
Maybe it is just different varieties, my plants are planar no matter 
what the growing conditions. I had assumed that all aloe plants were 
planar instead of radial...

    If you get a chance, separate out one small one and put it in a large
pot in the middle of a field. I suspect that if yours gets full sun they
will spread out.

    Do you live in the north?

Depends on where you live, I'm in south Michigan...I had some aloe 
planted outside on the south side of the house, and it did pretty 
well(after recovering from getting crushed by someone/something), but 
didn't spread out. I will try to remember to try this out next summer, 
but there may just not be enough light.

    Everything North of Jacksonville is Yankeeville.

    Unless they get some serious overhead sun I don't imagine Aloe will grow
right for you... I am surprised it will grow at all that close to glaciers.
