The pineapple(Ananas comosus) is actually an infructescence, and the real fruits are each bracts (“scales”) on it (as it is the case of strawberry, in which the “black dots” are the real fruits). It is a herbaceous plant (short growing), growing to about 1 meter tall, and perennial (with a long life span). The fruit does not have seed so you can plant the “crown” of the pineapple.
