Cosmos leaves

Cosmos plants are herbaceous perennials or annuals that can grow up to 6.7 feet tall. Cosmos leaves are simple, pinnate, or bipinnate and are arranged in opposite pairs. They are narrow, pointed lobes that curve outward from a central vein or spine. The lobes are arranged in a symmetrical shape, with a single or twinned lobe at the end. Each lobe has several pairs of small, pointed extensions along its length, and the base of each leaf is broad and flanged.
