This plant isn't an orchid as stated. It's related to Hoyas, in the family Asclepiadaceae. Grows as an epiphyte on trees where it can completely 'veil' over the trunk and branches. It likes high humidity and warmth. And it can be grown without soil.

Just rescued this plant from Lowes. The tag it came with gave very little care instructions, but so far it seems to be doing fine. I had no clue this was a member of the orchid family! The tag did say medium light, however it started to whither, so I put it under something a little stronger and it has sort of evened itself out. No new growth, but no new death either. I think it needs to be in something a bit more shallow. Im hoping to get it outside in the spring, if I can keep it going through the rest of the winter. Pretty plant, though!
