Instructions

Difficulty: Easy

Step1

See yellow. The most distinguishable characteristic of a Blackeyed Susan is its bright yellow petals. The petals are medium in size; each petal is about 1-2 inches from center to tip.

Step2

Look at the center of the flower. Blackeyed Susans, true to their name, have dark purple-black centers and a dome shape. Sometimes the center will appear brown and fuzzy.

Step3

Touch the stem. Blackeyed Susans have a scratchy, rough stem.

Step4

Examine the leaves. This wildflower's leaves feel hairy when you touch them and are shaped like a mini-sword or shaft with a pointed end.

Step5

Measure the height. Blackeyed Susans are generally 2-3 feet tall and stand very straight, like a person trying to practice good posture.

Step6

Enjoy Blackeyed Susans in the summertime. Their most common blooming period is between June and August.

Tips & Warnings

The Blackeyed Susan is native to the United States. Although it's entirely possible to see the plant in other countries, double check the characteristics when you're plant hunting overseas.
Next time you drive through Maryland, look for the Blackeyed Susan--it is their state flower.
Blackeyed Susans can often be found by the side of the road or in open meadows. They are also commonly used to beautify outdoor areas.
Don't confuse Blackeyed Susans with Browneyed Susans, which have a smaller head and bloom in late summer through fall.
Blackeyed Susans do not grow well in soil that doesn't drain properly. If you see black stems, the plant is probably growing in a soil fungus caused by too much water.
