Those are are beautiful! You've got a green thumb! I had a one, but recently had to to toss it because it was overgrown and bent. The flower was a hot pinkish color.
Memory lane...My grandma used to have dozens...every color and flower pattern you can think of. I remember going to the store and buying her pots and potting mix which was a fun thing to do as a kid. She always gave me a little extra to get a treat.
