Dewayz, I'm definitely not a pro, but I know the basics. Here's one piece of advice that many people overlook: pay attention to what is around the plant. Remove the clutter and notice the background. Aim for the simplest, cleanest surrounding and background that you can achieve. No matter how wonderful your plant is, the viewer's eye will move immediately to surrounding clutter.
Also be careful with glass backgrounds. Your photo above isn't bad, but sometimes glass will bounce unwanted light or reflect things you don't want in the photo.
Play with your point of view. Rather than shooting from above (standing position), try moving down to the level of the plant or even lower, looking up toward it. Sometimes your POV will be determined by what part of the plant you wish to emphasize.
You can achieve a lot with a camera phone and a spot lamp plus maybe an overhead light. If possible, avoid using your camera's flash. If you must, try standing further away and zooming to between 1.5x and 2x. This is to weaken the bright flash, which can look harsh. If too close to the subject, it will blow out detail. Too far back can look grainy, so play with it.
Finally, take advantage of whatever editing tools you have. You don't need a fancy photo processing program. Minor cropping and color correction make a big difference. Nearly every photo can be improved with some cropping, even just a little.
Here are a couple of examples of what I've mentioned, taken just now in my kitchen.
Nice plant, but clutter is distracting
