I love Native California plants and Non-Native Desert Plants like Cacti and Suculatens.
I tend to only document plants that are in my area, I love knowing the names of plant life I see, including weeds that are non native to my area.
I also use this to document my personal collection of cacti and succulents. All these are Marked as Casual/Cultivated/Not-Wild with the tag "foofoo"
