Great article! I love learning about cool plants and these are awesome examples.
I would just advise that when using photos from other sources - or any materials from other sources, that they need to be documented in the article. Something simple like:
[ Source Name ] ( url of image ) - remove the extra spaces and it will work.

I found you thanks to @shari-loveurlife's entry for the Pay it Forward curation contest. Keep up the great work!
