Hetty: That is one Gorgeous orchid! Gee ... I wish folks in our area would throw things like that in the trash!! Lucky find!
I don't know much about orchids but I love growing them and I have a few. I got a surprise bloom this morning with this orchid I purchased a couple of months ago at either Home Depot or Lowe's. There was a tag in the pot with a picture of a much different orchid ... which is what I thought I was getting. Down in the potting medium was another tag and it ends up being that one. Not as pretty as the one I thought I was buying but it's pretty just the same. I really don't know who comes up with these names!
