If one or more of the layers (whorls) is missing, the flower is known as an incomplete flower. Bisexual flowers.

What are the four main types of flowers?
A stereotypical, or complete, flower is made up of four kinds of structures arranged in sets (whorls) around the tip of a short stalk or axis, called a receptacle. The four main whorls (starting from the base of the flower or lowest node and working upwards) are the calyx, corolla, androecium, and gynoecium. The flower are the specialized part of an angiospermous plant that occurs singly or in clusters, possesses whorls of often colorful petals or sepals, and bears the reproductive structures (such as stamens or pistils) involved in the development of seeds and fruit.A flower is a fragile blossom that has petals and grows at the top of the stem of a plant. Flowers attract bees, who help out with the pollination process so more plants can grow. Roses, daisies, and carnations are all types of flowers. Flower is also a verb meaning to bring forth flowers.A complete flower is a plant biology term that refers to a flower that is made up of four parts: sepals, petals, pistils, and stamens. If any of these four pieces, which are essential in the formation of a flower, is absent, the flower is referred to as an incomplete flower.
Are marigolds perennials?
Annual vs. Perennial. In general, marigolds are considered tender perennials in warmer climates (USDA zones 9-11) but are usually grown as annuals in cooler climates. This classification is based on their ability to survive the winter months. Marigolds are typically grown as annuals, meaning they complete their life cycle in one season and do not come back each year. However, in warm climates, such as USDA zones 9-11, they may reseed and return the following year. Most gardeners replant them annually.Sow marigolds in late spring, or set them out as bedding plants. In climates with long, hot summers, make a second planting in summer for great autumn color. Broadcast seed into cultivated soil so that the seeds are about 2 inches (5 cm) apart and one-half inch (1 cm) deep.Marigolds are typically grown as annuals, meaning they complete their life cycle in one season and do not come back each year. However, in warm climates, such as USDA zones 9-11, they may reseed and return the following year. Most gardeners replant them annually.Marigolds are at the top of the list for a reason: These sun-loving annuals are super-tough, bloom from planting until a freeze, and have almost no pests. They come in heights ranging from 6 inches to 4 feet tall.
Which plants last the longest, annuals or perennials?
Perennials have a longer lifespan than annuals and may bloom for several weeks or months each year. Lavender, jasmine, wisteria, peonies, and ornamental grasses are popular perennial choices for gardens, providing consistent beauty year after year. Perennials are a flower garden’s backbone, providing beautiful color, texture and form. They are easy-care, dependable performers that come back every year.Which perennial flower has the longest bloom season? While many perennial flowers have long bloom times, the threadleaf coreopsis Moonbeam variety (Coreopsis verticillata ‘Moonbeam’) is a perennial with the longest bloom time. Moonbeam blooms early in the summer and will continue to do so until the end of the fall.Among the different types of plants categorized by their lifespan, perennials are known to live the longest. Let’s break down the types of plants: Annuals: These plants complete their life cycle in one growing season. They grow, flower, produce seeds, and die within a year.
