    These flowers are also called coneflowers as they have heads that are conical in shape but you should keep it in mind to not confuse these with the purple coneflowers or the Echinacea purpurea, which are a completely different thing. Both of these flowers are from the same family and their care is similar as well, but where they differ is their color and look.

    What people also confuse this flower is with the black eyed Susan vine or the Thunbergia alata which is a tender perennial that grows in a warm climate in Africa. Both these are completely unrelated and even though they sound almost the same, you cannot confuse one with the other because one is a flower and the other is a vine.


    Where And When Do They Grow?

    The black eyed Susan grows in zones 3 through 9 which includes places like Maine, South Dakota, Wyoming, places from the southern coast, etc. Although, mostly the place where they grow the most is based on their species.

    These flowers typically bloom around late July through late August or early September. A select few of the cultivars like the Early Bird Gold have a longer blooming period and they start flowering around the second half of the spring season.


    Physical Attributes

    The plants of the typical black eyed Susan can grow up to 3 feet tall and can have 6 inches long leaves and stalks more than 8 inches long. The diameter of the flower usually ranges between 2 to 3 inches. More generally, because there are a lot of cultivars of this flower, the size of the plant ranges from 10 inches up to 7 feet.

    Because of the variety in the cultivars, the diameter of the flower can be as big as 9 inches as well. These flowers can either be single, semi-double, or fully double. The petals of this flower can be bright yellow or orange-gold. Although there are cultivators out there who have managed to get a red, bronze, and even mahogany shade to the petals.

    If you look at the center of the flower, you will find that the black eye is actually dark brown, and isn’t that the case with people who have dark brown eyes? You assume they are black and that is why this name suits this flower so well. There are other cultivars like the Prairie Sun who have a different colored center like green but those are rare.
