Sunflowers, also known as the leaf blade, are a versatile plant that captures sunlight and converts it into energy. They are heat-tolerant, resistant to pests, and attractive to pollinators. Sunflower seeds can be harvested in late summer and fall for a healthy snack or feed to birds.
During the blooming stage, sunflowers transform into vivid displays of bright petals, attracting pollinators to aid in fertilization. As the flowers fade and seeds develop within, sunflowers can be harvested for personal use or wildlife use. Sunflowers are dicotyledons, with vascular bundles arranged in a ring inside the stem. The common sunflower is harvested for its edible oily seeds, which are used in cooking oil production and other uses such as food for livestock.
The outer yellow “petals” on the flowerhead are called ray flowers, which are made up of multiple petals fused together. Ray petals are usually yellow but can be orange. Sunflowers have other edible parts, such as the leaves, which are thick-walled cells that add mechanical strength to the stem, and the inside of the sunflower is composed of tiny disk flowers with five petals fused into a spiral. Each sunflower head can contain as many as 1000 to 2000 seeds.
Sunflowers have a high amount of fat, which often leads people to veer away from them. Understanding the facts about sunflowers, including their origin and how to use them, is essential for those interested in growing and using these versatile plants.

What chemical is in sunflowers?
Sunflowers emit sesquiterpene lactones (SL), a naturally occurring chemical that can inhibit the growth of some plants. This is a plant defense mechanism called allelopathy, and all parts of the sunflower plant contain SL. To protect sunflowers from these SL-sensitive plants, it is recommended to plant a “barrier” plant or plants next to the sunflowers. These plants should be resistant to SL, such as thyme, rosemary, basil, carrots, corn, legumes, dianthus, vinca, lemon balm, lantana, coral bells, dead nettle, daylily, and dahlia.
Plants that do not do well as neighbors include tomato, lettuce, kale, broccoli, cabbage, and some grasses. The majority of plants that produce sesquiterpene lactones are in the Asteraceae family, including echinacea, rudbeckia, daisy, and aster. These plants are good companion plants for sunflowers but may also add SL to soil.
