The largest bromeliad is Puya raimondii, which reaches 3–4 m tall in vegetative growth with a flower spike 9–10 m tall, and the smallest is probably Spanish moss.
Bromeliads are easy and colourful plants to grow in the warm climate garden. They do best if they have some shelter from the midday sun. They need light and some sun to bring out the colours in their leaves. They produce pups, their offspring, which one can cut off and plant again. Once the plant has flowered it will die, but not before it has produced one or several pups. I grow many different types,
Neoregelia, Nidularium, Vriesia, Aechmea, Tillandsia, Guzmania and more.
Bromeliads are one of the more recent plant groups to have emerged, presumed to have evolved at the close of the Cretaceous, over 65 million years ago. Fossilized bromeliads have been dated back to roughly 30 million years ago. The greatest number of primitive species reside in the Andean highlands of South America suggesting a beginning there. The west African species Pitcairnia feliciana is the only bromeliad not endemic to the Americas, and is thought to have reached Africa via long-distance dispersal approximately 12 million years ago.
Humans have been using bromeliads for thousands of years. The Incas, Aztecs, Maya and others used them for food, protection, fiber and ceremony, just as they are still used today. European interest began when Spanish conquistadors returned with pineapple, which became so popular as an exotic food that the image of the pineapple was adapted into European art and sculpture. In 1776, the species Guzmania lingulata was introduced to Europe, causing a sensation among gardeners unfamiliar to such a plant. In 1828, Aechmea fasciata was brought to Europe, followed by Vriesea splendens in 1840. These transplants were successful enough that they are still among the most widely grown bromeliad varieties.
