head
Quick Summary
A flower head, also known as a capitulum, is a type of inflorescence where sessile flowers are arranged on a main axis, making the entire cluster resemble a single flower. This structure is characteristic of the Asteraceae family, which includes plants like dandelions and sunflowers. In a head inflorescence, the youngest flowers are typically located at the center, with older flowers blooming towards the periphery. This arrangement allows for a prolonged flowering period.123
