|Florida Living Wall & Green Roof Plants Nature Selected (ferns), Ft. Pickens, Pensacola by Kevin Songer|
Old forts and other relic structures that have been in existence over time are plant laboratories, experiments in drought, heat, wind and salt tolerance.
Although in reality most green roof and living wall designers do not use these specific plants typically found growing across structures, the knowledge gained from examining wild roof and wall plants is invaluable.
Identifying and classifying these found plants as to their Genus and Family classifications can help select other related but more suitable to vertical landscape plants.
Examine those plants you seeing growing downtown when you are out and about. Nature has so much more to teach us than the most detailed scientific manuals!
