I had to laugh (well, only a little) at one gal who commented on my site; she accused me of making a mistake, and that there are only really three kinds - a red kind, a green kind and a cobweb kind, and that the only reason my plants look different is that the pictures were all taken when the plants were in different stages of dryness, I tried to be kind and pointed out that all the pictures on the page in question were taken at the same time. I don't think she believed me.
