Let us explore which among these is white silk cotton.
A) Sida- It is a species of flowering plant and is considered a weed in some areas. It is believed to be originated in Central America.
B) Ceiba- in the American tropics, the Ceiba tree or the white silk cotton is a huge tree. It’s scientific name is Ceiba pentandra.
