Although not a true Rose,but looks like one I was given a Black Swan Desert Rose from our Vietnamese neighbor who has about 200 of different varieties of them.Some are two to three foot tall with basketball sized trunks.Very impressive and the easiest to care for.He has sold the larger ones for up to $1000 bucs each to some real diehard interior designers and photographers.Almost like a Bonsai type looking Rose/Tree.
