Offered for sale are pups from Brocchinia reducata, a carnivorous bromeliad native to South America.  Your plant could vary in size from approximately 3″ to 12″ in height.  They are un-bloomed offsets.

You will receive 1 pup that may or may not have roots at the base of the plants.  No worries, the roots are only used to anchor the plant in place.  I recommend diatomite and coconut coir for potting media, but any well-draining mix will do.  Shipping for Brocchinia is $15 for Priority Mail delivery regardless of the quantity of plants ordered from my shop.  We ship Mondays and Tuesdays.
