- Does flora - trees, flowers, earth contain prana?
- Is this a cosmic energy that is set in earth and nature?
- Do living organisms contain that energy?
- Can it heal or give you its power?
Energy means power, yes trees, flower have them. This energy lasts for some time only. Like when a flower rises its power lasts for 1-2 days, after this time flower or leaves fall. Every thing has its time.
what is prana? does flora - trees, flowers, earth contain it?
Prana is there in trees. Are you asking Prana means "Jeeva"? If yes then yes trees are considered as living beings.
Tulasidaskrut Ramayana When Lord Rama was asked why he hide himself behind trees and killed Vali? There is mention that those trees were cursed 7 sages who became 7 trees of "Tada" <- I do not know its English name, whom Lord Rama freed by his arrow only!! This means their energy is there. Prana should also be there.
In Shiva Maha Purana Mother Parvati converted 4 deities and Guru Brihaspati in trees, on Lord Shiva's advice she freed them too.
Earth is a goddess in Hinduism, so it should be living being I guess, in reality I do not know. :)
Varah Puran Goddess Earth is there whom Lord Vishnu told the importance of Shrimad Bhagwat Geeta.
Can it give you power? Is it used for healing?
Also we eat them and we get energy from them. Many plants are used to make medicines, so they are used for healing.

Fire has three Kalas, Vayu (Air element) has four, and the Space or Akash has five. Plants and trees are said to have six Kalas. Animals have seven Kalas. Human beings have eight Kalas.
If it is an extraordinary human being then he is said to have nine Kalas...
