Floral scents head canon. · 5:26am Oct 9th, 2019
With how often Twilight is described as smelling like lavender in fan fiction, I've developed a bit of head-cannon that all Equestrians (pony or human) have natural, vaguely floral aroma. And that the "love juice" of females have a flavor associated with this scent.
Characters I have this h.c. for and their associated floral scents and tastes:
Princess Twilight Sparkle - Black Sage / Black Sage nectar
Human Twilight Sparkle - Purple pitcher sage / Purple pitcher sage nectar
Sunset Shimmer - peach blossoms / Gold dust peaches
Pinkie Pie - Roses / Rose hips
Fluttershy - Cherry blossoms / Rainier cherries
Applejack - Apple blossoms / Blondee apples
Rainbow Dash - Chicory / Chicory blossoms
Rarity - Mangosteen fruit
Adagio Dazzle - Nasturtium
Sonata Dusk - Borage flowers
Aria Blaze - Mission Fig
Huh. Weird but neat concept. And it does make sense if you extend the whole "lavender unicorn is lavender-scented" thing to its logical conclusion. Though associating Rarity with mangosteen makes me think of the Pokémon Tsareena, a.k.a. the mangosteen dominatrix. (Seriously, its previous form evolves when it learns Stomp.) Not sure if that's a coincidence or exactly what you were going for.

Well, re: Rarity, it's her color scheme (purple and snowy white, like a mangosteen), and, y'know, how exotic, rare and valuable the fruit is. Where I live, on the rare occasion that any of the markets have fresh mangosteen, it goes for ca. $25 / lb.
If that's not Rarity, I don't know what is.
And I'm sure Rares would be a good dom. I can easily imagine her stepping on someone if they asked nicely (or begged, depending on the situation).
