RE: big old walnut tree

I have a few to show for now,
A coconut tree: it among the expensive trees Fun fact in my country (Zanzibar) : you find two ownership in the same plot (the owner of the coconut trees and the plot owner), coconut tree provides coconut juice (special taste when fresh?), coconut oil, coconut leaves are used to make roofs of house traditional style in Zanzibar, so it worths it

Agave plant : this is a century plant. Its very protective always, with has sharp thorns you cannot even think about coming close to it
In swahili it's ( mkonge pori)

And lastly we have,
Plumeria pudica, this is a species of the genus Plumeria, native to Panama, Colombia. It's flowers are white with a yellow center, source@google
