The pink pineapple is an ornamental species of pineapple from Brazil. Characterised by its pink inflorescence, its proper name is Ananas comosus var. ananassoides and while between 4-5 cm in length it sits upon a stalk which can be upto 40cm tall. They are edible but because of their strong acidic taste they are rarely eaten.
In nature, bees, butterflies and birds are attracted to it, and outside of nature, human beings like me :)
