Need some suggestions

I am new to this group my name is Brian Williams. I live in Louisville KY and I am currently working on a large display greenhouse. I have been growing a lot of plants for the past 10 years and aroids are my specialty. I have recently gotten more interest in orchids and bromeliads as well as gesneriads. I really enjoy the specie forms and the highly unusual rather than the african violet types. I have a rock wall that is 40 feet long 10 feet tall in a large greenhouse the low temps are 60f and the highs maybe 95 or lower around the wall. Their is a misting system that comes on every half hour for 15 seconds. I am looking for someone who may grow odd species that would have plants that would like this situation. I seem to be very fond of Columnea species and other small trailing or hanging varieties. The only hybrids I have seemed to like are of the episcias which I would also like to find more forms of. I like the more metallic to variegated forms it seems of these. If any of you are growing many of these and would be interested in a trade please let me know or if you know of a source for them. I am sure their are many other odd species that I do not know about but would love to find or hear about. I have many plants in my collection and a few gesneriads already and help would be great thanks.

Here is a photo of some species I took photos of at Atlanta Botanical gardens recently.

Hi Brian I've been watching your great interesting wall ! I may have a few plants you'd like ? I will Dmail you.

Hi Brian.

Obviously you have your pick of columneas and aeschynanthus.

As far as odd species are concerned, you might consider a unifoliate streptocarpus or some of the sinningias. I don't know how small you can go, but some of the micro mini sinningias (about 1-2" in diameter and height) grow on vertical cliff faces and are really rather unusual and cute.

Unifoliate streps don't have much wow factor, and some are monocarpic, but they are interesting botanically speaking. Not sure if this one is available in the US: http://gesneriads.ca/strep203.htm
Many of the others are grown by enthusiasts and are available in seed form from the gesneriad society
haygarthii http://gesneriads.ca/strep201.htm
gardneri http://gesneriads.ca/strep199.htm
primulifolia http://gesneriads.ca/strep184.htm and http://gesneriads.ca/strep185.htm
rexii http://gesneriads.ca/strep110.htm

Some of the Sinningias that might work - again not WOW type things, but these do have tubers:
sp. Ibitioca http://home.earthlink.net/~sinnvenner/4ibit.htm
sp. Rio das Pedras (micro mini) http://home.earthlink.net/~sinnvenner/4rdps.htm
cooperi http://home.earthlink.net/~sinnvenner/4coop.htm
douglasii http://home.earthlink.net/~sinnvenner/4doug.htm
glazioviana http://home.earthlink.net/~sinnvenner/4glaz.htm
calcaria (not sure if I've seen this one available) http://home.earthlink.net/~sinnvenner/4calc.htm

Speaking of orchids, has someone suggested a phrag lithophytically?

oh, and I'll send you dmail.
