Any scent in the realm of including: woods, greens, natural unusuals. Woods being plants, or wood types in general, such as: logs, pine, maple, etc. Greens being non-flowering plant species and similar such as lemonbalm, parsley, etc. Natural unusuals being things in nature such as rainwater, meadow, or fruits.
This scent category includes desserts, gourmands, culinary, and drinks- which can be any assortment of types of food items. Different examples such as particular cinnamon rolls exist, or different sodas, and the list continues. A very broad category.
This category includes any number of smells of manufactured types such as candles, soaps, perfume, etc. These scents may have natural influences, but would be from a candle or a soap rather than the object itself (or combination of objects). Detergents fall into this category (being soaps), but more astringent cleansers (like bleach) would fall into a higher rarity class.
