They are the creations of Paloma Teppa, a local Miami floral designer whose company Plant the Future was responsible for all the greenery at the ELLE Spa.
In addition to the unicorns, Teppa's work incorporates rabbits and foxes and pigs and bears--oh, my! Although mostly, the white sculptures are smaller and placed in arrangements of succulent plants and glass bowls or vases.
If you are tickled pink by these guys post-scrub or facial, you should know that Teppa's Plant the Future studio is in the Wynwood arts district, where you may just be able to scoop up a unicorn of your own. For something more likely to fit in your carry-on and not alarm the TSA, you can head to cool concept store Base on Lincoln Road, which sells some of Teppa's table-top-sized bunnies bearing succulents.
Oh, and to see the ELLE unicorns, you have to book a treatment--since they're beyond the gift shop and locker rooms. But the good news is, it's still Miami Spa Month--at least until August 31!--so you can see them for just $99 plus tax and tip.
