I'm just a travelin' with Stuffies and excessive Cheesefesting person with an interest in plants that has a digital camera.
Generally I mark all my plant/flower/tree photos as CC-NonCommercial. If you want to use a plant image that doesn't seem to be marked that way, drop me a FlickrMail as it was probably just overlooked.
If for some crazy reason, you want to use one of my photos for something, just send me a FlickrMail. Mostly I just want to know for curiosity's sake.
