THE SUNFLOWER FAMILY
 
The sunflowers are found around the globe in many different places, from temperate climates, like in Saskatchewan, to mountains or in dry regions. The sunflower family is very large and contains about 19,000 species! As you can imagine, the plants in this family can look very different from one another. The sunflowers can be shrubs or herbs, with many different leaf shapes and flower colours. One thing that is common to all sunflowers is the type of flower arrangement. In this family, there are many flowers grouped together into a head, like the one you see on a daisy. It looks like one flower from a distance, but when you get close you will see that it is actually made up of many, small flowers. The head may have ray flowers on the outside and disc flowers on the inside, or only one of the two kinds. Many of the seeds, like the dandelion, have a fluffy structure attached to the seed. This is called the pappus and helps the seeds to spread in the wind.

You probably know a lot of plants in the sunflower family. Sunflowers can be plants you eat or plants that you may grow in the yard. For example, did you know that lettuce is from the sunflower family? So are the marigolds in the garden! Maybe you have heard of Echinacea? It is a plant in the sunflower family that is used to make medicine. Some of the sunflowers are also weeds, like the dandelion.
