Yes, for sure. I carry medicine bags around my neck (even right now as I am writing this answer) with herbs and gems/stones. They are very important for me in many ways.
I also work with elementals: Sylphs, Ondines, Gnomes and Salamanders - the guardians of the Elements. Air and Water are my strongest guiding Elements. I am happy You connect with Water as well, it is a beautiful Element and so are its guardians, the Ondines!
I connect with the Spirit World too. There are many ways for that.
Interesting question. May Wakan Tanka guide your path. All the best!
I love the outdoors and it helps me to "clear my thoughts" and feel good to be outdoors, but I do not have a spiritual connection with plant forms or anything other than humans, animals and God. I love trees, plants and the ocean and other bodies of water, but not in the same way I love animals, people and God.
