never saw a hawthorn.
i read in my fairies book:

It symbolizes hope.
Like all thorn bushes, the hawthorn is a sacred gathering place of the elves.
However, it has the reputation of being unlucky.
farmers from europe smell the plague from the scent of the hawthorn. perhaps for this reason, or from even older memories, it is considered disastrous to bring it into the house.
that's just what i read. i don't know if it's true. but you should always look at both sides of plants, even though i romanticize some plants.
it is a very strong heart tonic.
Blacksmiths liked to use the wood of hawthorn because it burns the hottest.

however, because i have never found it myself, i have not yet studied the legends and mythology of the bush in depth. so this is only superficial information that you should not be irritated by.

it should also be noted that christianity has demonized some plants. so that people no longer dare to deal with them. this means that we no longer know the true kernel, but only the information that christianity has associated on the plant.
my assumption is that plants help us to tread our soul path and the current system prevents this on all levels.
