inspiration: moss graffiti + mimosa lettering

I want to use this technique of moss graffiti to create our outdoor signage at the shop ... a green living and growing sign that reads: BOTANY. Here is where I got the inspiration from ... 

Anna Garforth describes her project Grow ... "Moss typography adorns the wall of a secret spot I found in London behind locked gates, a disused plot awaiting the arrival of new flats. I thought I'd sneak in before the small wilderness got bull dozed." 

And I love how she used mimosa flowers in her typography project Pollinate..."A type face inspired by spring using dried, pressed flowers."
