A couple years ago, I saw blooming of Black Jack flower on the river banks of our neighborhood.
In addition to Black Jack, the flower with scientific name Bidens pilosa, has many common names such as cobblers pegs, hitch hikers, farmer's friends, Spanish needle and Beggarticks.
Unfortunately, It seems the flowers disappeared from the river banks for this year, luckily, we have observed in our neighborhood. They are planted as a home garden flower.
Interestingly, we may find this flower blooming in many tropical and subtropical countries around the world, spreading from its origin areas of South America.
There are plenty of pollinators for Black Jack flowers, some of major pollinators Bees, Butterflies, Moth and Syrphid (Diptera).
Based on GoogleID, The pollinator on image 1 and image 3 is Bumbblebee. It is powerful pollinator for many plants.
Have you seen Black Jack flowers in your areas?
