Comfrey
Botanical Name: Symphytum Officinale
Comfry is one of the best plant companions out there. It can make a great fertilizer for other plants due to its deep roots (6-10'). Because of their depth they extract nutrients from the subsoil, which is not often accessible by other plants. See the video below by Homesteading with the Zimmermans on how to make this fertilizer tea.

More Detail on Companions:
Comfrey enhances soil fertility by drawing up essential nutrients from deep within the soil and making them more accessible to neighboring plants near the surface. Comfrey is recognized for its ability to supply the essential nutrients nitrogen, phosphorus, and potassium, which are the primary elements required for optimal plant development.
Pruning Tips: To prevent the plants from spreading, trim them back once they start blooming.
When to Harvest: Comfrey leaves can be harvested at least 4 times a year starting mid-spring. Then start harvesting leaves about every 6 weeks until early fall. Stopping in early fall will allow the leaf out and build up winter reserves.
Harvesting Tips: Cut the leaves back to about 2 inches above the soil. It's best to cut the big leaves on the bottom of the plant so it can focus on the higher smaller leaves to grow and also allows more light to the bottom of the plant. When harvesting the roots, wash them in cold water, then cut them into small chunks and dry them out.
**When foraging for wild herbs, be sure to pay attention to where you are getting it from. Be cautious about harvesting plants grown in potentially contaminated areas like roadsides, driveways, unfamiliar terrain, and areas that may have been sprayed with herbicides.
If ingested: It might be toxic to dogs
