I love them all! But, I am a tropical loving girl and I have always said I ended up in the wrong growing zone. lol
I once grew the plant in the first photo which is rather difficult. I think it was called a bat plant as the flowers looked like a bat in bloom. I don't know the latin name but it really does not matter. Those flowers are superb and I wish I had a conservatory that was also a butterfly habitat. That is my wish list. Have a great day old-guy.
