I've ordered from a variety of places, but haven't ordered any in the last few years. I think I recall Cap Cod Violetry having the widest selection. They do not have a website that I can find, but here is their contact info:

I bought some from Bluebird Greenhouse, over the 'net. Of course this meant I saw and then had to order two plants (but they sent three), so use judgment. I chose Bluebird because I could order pots and flowers to ship together, while other places wouldn't ship them together and I wouldn't have been able to slip the two plants into the order. :D

Also, try the individual fruit cups or applesauce cups (like the Mott's Minis, though I buy generic). I have my sucker in one and plan to use them for small pots. They're the perfect size and wider than tall.

Here is a link that might be useful: Bluebird Greenhouse

I like my Oyama pots. I have my minis in 1.5" and the semis in 2.5". They are doing really well.

I use 3" plastic bathroom cups.

Which do you consider more important with the size. The diameter of the top or the over amount of room for soil and roots? Hmmmm not sure that makes sense to anyone but me. Lets say you have a 2.5 in pot and it holds a little bit more then 2 ounces. (I measured using water just to see) Then you have a container that is bigger around, 3 inches, and shorter but holds the same amount, 2 ounces. Do you think it makes any kind of difference in the long run to the plants growth?

Ha, I started typing out a response and realized that I have no real idea except perhaps aesthetics :D. All I know is that the trailing AVs are typically grown in pots that are wider and more shallow than the azalea pots that regular AVs are grown in.

AVs are shallow rooted. The pot needs to 1/3 the diameter of the leaf spread. The depth can be about the same. Or shorter in some cases.

Tommy do you know why that is? Just trying to understand the reasons behind the rule. Use to get me in trouble with my parents and teachers lol.

I am NOT an AV expert first of all so corrections are always welcomed. They have a small root zone and do not need a lot of soil and too much soil can lead to root rot. That goes for ANY plant by the way.

Wouldn't it be the same amount of room just in different directions if both areas measure slightly more then 2 ounces? In the 2.5 pot the roots have room to grow down and in the shallow 3 inch they have the same room but grow out instead. At least that is how it seems to me. I was wondering if there isn't some other reason for the diameter.

I'm not sure the shallow root system applies to all a/vs.
I have a Genuine Jewel which I just repotted and it had a massive root system.
And interestingly enough there was one in our annual show last year in what most of us would describe as a totally oversized pot.

AV roots like to be contained. After repotting the first thing they seem to do is shoot roots out to find the limits of the pot. After you have repotted AV's for awhile you will see.
