Nice. I use a Canon Powershot S3 Is or something. I don't have any macro lenses.
I love taking pics with black backgrounds. All I do to do that is put something black behind the plants I'm photographing, and aim two CFL's on the plant and away from the black background and take pics. Most of the time I'm too lazy to use a tripod, so I just rest the camera on the pot or my knee to keep it steady.
