Daisies, sunflowers and asters are all members of the Asteraceae family, and their exact count varies according to the source.
Till date, experts have documented more than twenty thousand species of daisies. The Flora of North America Project has accounted for around 2,413 species in North America alone.Members of the Asteraceae family are mostly easy to identify. This is primarily because of the distinguished physical trait which is present in a majority of them, like a central disk or eye surrounded by thin, multiple petals.
Identifying these species is not easy and can prove to be very difficult for anyone who is not an expert in the subject. A few popular daisy varieties are African Daisy, Balsamroot, Blazing Star, Blue Mistflower, California Brittlebush (coast sunflower), Chicory, Coltsfoot, Daisy Fleabane, Desert Chicory, Desert Dandelion, Firewheel, Gold Star, Goldeneye daisy, Goldenrod, Mexican Flame Vine, Mule Ears, Orange Agoseris, Oregon Sunshine, Pearly Everlasting, Western Cone Flower and Flower Power. Most of these varieties are native North American plants, and are usually found growing in natural fields.
Some varieties like Balsamroot, Brittlebush, Gold Star, Goldeneye daisy, Mule Ears and Oregon Sunshine fall into the yellow petal category, like the sunflower. These are identified by the flower head size, shape, shape and size of the leaves and petals. Some like blazing stars and blue mistflowers are members of Asteraceae genera, but do not look like traditional daisies. The more colorful ones like the African daisy, Mexican Flame Vine and Firewheel are big hits with gardeners, especially as a fall plant.
