A word/phrase which refers to the smell of nature?

Similar to the word 'petrichor' in its purpose. I'm looking for a word/phrase that can be used to describe the smell of grass/pollen/trees/wood/earth essentially the outdoors.

Similar to the smell of a garden or wooded area in the summer or perhaps freshly mowed grass?

It's not specifically olfactory, but I'd use Bucolic:

of or characteristic of the countryside or country life; rustic (-- Collins)

The "outdoors" smells like a lot of things! I can think of a words referring to various specific scents that recall being out in nature:

earthy, woodsy / woody, mossy, mildewed, moldy, pine, loamy, flowery, fresh. And more of a stretch: crisp, musky, animalic, sweet, heady (like 'the thick smell of nectar')

Woodsy fragrance is broadly used to refer to the smell of forest.

Woodsy is defined in Merriam-Wesber:

relating to or suggesting the forest
