This rose was at the property we bought in 2005. It did not have a tag on it...It also had not been watered for about 4 months. I did not think it would survive...I moved it and fed it, watered daily and it started to grow. It is a beautiful rose. About two years ago I found a tag where the rose had been planted. I thought that it when blooming and lush leaves that it was Rio Samba. That is what I told everyone. LOL We have moved but I brought the rose with me. It is now looks more like the pics on Dave's Garden website at our new address. It is still suffering a little since this last move. Its colors were more pronounced at our former location. I love and others have admired it.
