|The actual flowers of the Poinsettia are tiny and clustered
within green cups, which themselves are clustered within a
mass of bright red bracts. Nectar is produced in the yellow,
mouth-like appendages on the sides of the green cups.
In some cases, what appears to be a single flower is a dense cluster of flowers, with specialized, petal-like flowers arranged in a circle around them. This is the highly successful strategy of the sunflower family.
|In the Anthurium, the actual flowers are
the tiny bumps on the long spadix.
For additional examples of "false flowers," I refer you to my article of several years ago in Florida Gardening Magazine: False Flowers
I also featured two genera of the Araceae in Florida Gardening articles: Amorphophallus and Calla lilies.
For a nearly complete list of my Florida Gardening articles, and for a link to the website where you can find an index to all of their articles, go to Florida Gardening Magazine. The magazine is devoted to gardening in Florida, but in my own articles, I often explore more botanical questions. The magazine is also followed by people in similar subtropical climates around the world.
