Petal Petal Petals are modified leaves that surround the reproductive parts of flowers. They are often brightly colored or unusually shaped to attract pollinators. Together, all of the petals of a flower are called a corolla. Petals are usually accompanied by another set of special leaves called sepals, that collectively form the "calyx" and lie just beneath the corolla. The calyx and the corolla together make up the perianth. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term "tepal" is appropriate include genera such as "Aloe"
Lophospermum scandens with age and developing a woody caudex – a swollen, bulb-like structure at the base of the stem. The leaf stalks (petioles) are long, occasionally twining to grasp supports, thus enabling the plant to climb. The leaves are narrowly heart-shaped, long by wide, with a pointed apex and toothed edges (dentate or crenate). The leaves and stems are sparsely covered with short hairs. "Lophospermum scandens" flowers and fruits from May to November in its native habitat. The flowers are borne singly on stems (peduncles) long. The calyx has sepals that are generally narrowly ovate, long and wide at the base,
