Yellow Annual Flowers

Marigolds

• Marigolds are part of the Asteraceae family and come in a variety of colors including bright yellow. They range in height from less than 1 foot and some can grow taller than 4 feet. They have a circular shape in which several petals grow on top of one another, forming what looks like a fluffy ball. They thrive in areas that receive partial shade and like moist soil. They have a pungent smell that keeps insects at bay, which make them an ideal flower to plant with other flowers or vegetables that attract pests.

Gerbera Daisy

• Showy gerbera daisies are members of the sunflower family. The single flower consists of long petals that grow in a single or double layer around a prominent disc-shaped center. The bloom sits on top of a stem that grows anywhere from 6 to 18 inches. The petals of these flowers come in a variety of colors, including bright yellow. They like full sun exposure and damp soil. These flowers make lovely additions to bouquets.

Zinnias

• Zinnias produce blooms that grow in a disk shape with either a single layer of petals or a collection of petals piled on top of one another, forming a dome. The blooms grow on a single stalk that can reach heights of anywhere from 5 inches to 3 feet. Available with blooms in both pale and bright yellow, they grow well in nutrient-rich soil that is exposed to full sun. They require moist, well-drained soil.

Snapdragons

• The snapdragon hails from the genus Antirrhinum. The flower acquired its name because the petals resemble a dragon whose mouth snaps opened and shut when pinched. These flowers are classified by their height --- dwarf, medium and tall --- and range from 10 to 24 inches high. Several blooms grow in a spike formation, and they come in an assortment of colors, including yellow. Plant these flowers in full sun and moist soil, and you'll have abundant blooms throughout the summer that may last beyond the first frost of fall.
