Red pineapple (Ananas bracteatus) is an ornamental that originates in South America. It looks like a spiny red plant, but it really has three things going on. The red spiny parts are bracts. Between them are the equally red, but rounded inflorescences. Finally, from the inflorescences emerge small purple flowers.

The long green leaves are also spiny, so it’s no surprise to learn that these plants, which can grow up to four feet tall, are often grown as security hedges.
