What kind of tripod is best for flower macro photography?

Question

What kind of tripod would you recommend for macro photography? The subjects being flowers low on the ground. I have a fairly good tripod but the center column gets in the the way meaning that I can't lower the camera enough.

With this tripod, I can place the camera upside down. Sorry for asking but is this an usual macro photography way of shooting? My setup consist of a T2i, extension tubes, focusing rails and external live view remote.

Edit: This is what I mean by "upside down".

Answer

Well, I'm not sure what you mean by 'with this tripod, I can place the camera upside down' - but many existing tripods can invert their center post and allow you to place the camera between the legs of the tripod. This may or may not be sufficient for what you're asking, its difficult to tell without seeing your setup.

Other options may include a tripod like the Manfrotto 055XPROB which has a center post that can rotate and tilt over its legs (see the picture on the included link). This would allow you to get closer to your subject if the other method doesn't work.
