Flowers That Are in Season in September

Updated July 19, 2017

Some flower varieties are available year round: roses, carnations, lilies, daisies and orchids. However, most flowers are seasonal and only bloom during specific times of the year. If it is September, and you are planting flowers in your garden or purchasing flowers as a gift for a friend or loved one, it is important to know which flowers are currently in season. They will be readily available and less expensive than flowers that are always available.


Also known as mums, chrysanthemums are perennial plants that bloom in late summer and early fall. The blooms come in a variety of shapes including daisy shaped, button shaped and pompons. The blossoms are available in red, yellow, orange, purple and white. This plant's flashy and colourful blooms make it ideal for decorating gardens and patios. Chrysanthemums do best in full sunlight.


Dahlias are perennial plants that first originated in Mexico. They bloom from late summer until the first frost. The blooms come in a range of shapes, sizes and colours. Some dahlia plants are only 12 inches tall while other species of dahlias can grow to a height of 8 feet. Dahlias are popular for landscaping and make great cut flowers. They do best in full sun and should be watered at least once a week.


Marigolds are annual plants that bloom until the first frost. The blooms come in many colours including yellow, red, orange, white and multicoloured. Marigolds are known for their strong odour and are used to repel insects. The plants are available in a variety of sizes ranging from 6 inches to 4 feet tall. Marigolds make great cut flowers and are used to edge flowerbeds. They do best in partial-to-full sunlight. The soil should be kept slightly moist.


Sunflowers are annual plants native to North and South America. They can grow up to 12 feet tall and typically bloom in late summer. This plant's flower is known as a head and is composed of approximately 1,000 to 2,000 individual flowers. The petals on the outer section of the head are most commonly yellow, but they can also be orange or maroon. The brown centre of the head turns into seeds when the plant matures. Sunflowers are commercially grown in America for these seeds. The seeds are edible and can be used to produce sunflower oil. The large vibrant heads of sunflowers make them great plants for decorating flowerbeds and gardens. Sunflowers grow best in moist soil and full sunlight.
