| 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. |

| Slender hawksbeard is 15 to 70 cm tall. The taproot is long and thin. The stem is branched and woody at the base. If you break the stem, you will notice a milky juice, like in the dandelion. The leaves are mostly basal, and the leaves on the stem are very small. The basal leaves are usually woolly-hairy with a purplish midvein and are lobed on the edges. The last lobe is long and pointy. The flowers are in heads. The yellow ray flowers are toothed at the tip. The fruit is yellowish-green and has a white, barbed pappus. | |||||||||
| WHERE DOES IT GROW? | |||||||||
| Slender hawksbeard is found on open, grassy slopes. | |||||||||

| This plant is found in the Cypress Hills and surrounding area in the Cypress Upland and Mixed Grassland ecoregions. | |||||||||
| WHY IS IT RARE? | |||||||||
| Slender hawksbeard is endangered in Saskatchewan because it grows in small clumps in the southeastern part of the province and is vulnerable to habitat loss. | |||||||||
| HOW TO IDENTIFY SLENDER HAWKSBEARD | |||||||||
| * Are the ray flowers yellow? * Are the leaves deeply lobed, with the last lobe long and pointy? * Are the fruits greenish? * Did you find it in the Cypress Hills? | |||||||||
