Awesome Symmetric Plants

These symmetric plants are awesome!

Notes: The web page advertises 25 plants, but they appear to only include 24 of them. Also, the symmetries aren't literally "perfect", though many of them are really damn good. However, while the hyperbole of the title is a bit grating, the plants themselves really are awesome. Naturally, many of the different plants are also have different symmetries.
