You may have heard people say that cacti only flower once every seven years.
This is not true. Once a plant is old enough, it should flower regularly every year.
Some plants will flower after only two or three years from seed.
Others need to be much older, perhaps as much as 100 years old before they will flower.
Cactus flowers may be red, orange, yellow, white, pink or magenta, but never blue. They might be bold and spectacular, or more delicate.
What’s different about the flower on the right?
All the flowers shown above are round, and even in shape. This one isn’t, it’s an unusual irregular shape.
Flowers that are irregular in shape are known as zygomorphic.
This is a Christmas cactus, but there are other cacti with similar irregular flowers.
