Although September in the Gregorian calendar is a great season for harvest, there are also many flowers that bloom in September, such as osmanthus, red spider lilies, night-blooming cereus, lotus, oleander, gomphrena, and hibiscus, all of which bloom in September.

Besides these, do you know any other in-season flowers for September?

In the following, I will share with you ten types of flowers that bloom in September. Let’s explore them in detail.

1. Osmanthus – Blooming period: September to early October

What flowers bloom in September? The first one that comes to mind is osmanthus. Its blooming period is from September to early October, making it an excellent ornamental tree that combines greening, beautifying, and fragrance.

As one of China’s traditional top ten flowers, its scent is pure and can waft a long distance, making it truly remarkable.

Especially during mid-autumn, when osmanthus flowers are in full bloom, it is refreshing to appreciate the flowers with a glass of wine and its fragrance fills the air. Its number in ancient Chinese floral poems is also considerable.

It has long been loved by the Chinese people and is seen as a traditional famous flower. There are many horticultural varieties of osmanthus, the most representative of which are golden osmanthus, silver osmanthus, orange osmanthus, and laurel. Osmanthus can be used in food and cosmetics, for making cakes, candies, and for brewing wine.

2. Chrysanthemum – Blooming period: September to November

There are quite a few flowers that bloom in September, and chrysanthemums can definitely rank among the top three.

Chrysanthemum is one of the top three flowers in China, one of the “Four Gentlemen” in flowers (plum blossom, orchid, bamboo, and chrysanthemum), and also one of the world’s four major cut flowers (chrysanthemum, rose, carnation, and iris), with the highest production volume.

Chrysanthemum’s blooming period is from September to November, making it the undisputed master of autumn.

Whether it’s cultivated varieties like the standard chrysanthemum, desktop chrysanthemum, cliff chrysanthemum, big daisy, small daisy, Japanese small chrysanthemum, or wild chrysanthemums like the field chrysanthemum, cow’s knee chrysanthemum, fengmao chrysanthemum, kingfisher chrysanthemum, small red chrysanthemum, aster etc., all bloom in autumn and are marvelous to behold.

Not only are chrysanthemums highly ornamental, but they can also be used medicinally. Long-term use or drinking chrysanthemum tea can lead to longevity.

3. Red Spider Lily – Blooming period: September to October

Which flowers bloom in September? We can’t miss mentioning the red spider lily. It blooms from September to October and comes in red, white, and yellow.

The Japanese name for the red spider lily is “Manjushage”, translated from the Sanskrit “Maha Manjusaka” in the Lotus Sutra, meaning the heavenly flower, the big red flower.

It is one of the four auspicious heavenly flowers (Manjusaka, Maha Manjusaka, Mandarava, Maha Mandarava), which when seen, is said to eliminate evil.

The red spider lily we usually refer to is red lycoris radiata. The common white lycoris radiata and yellow lycoris radiata are not technically “red spider lilies”.

They are close relatives of the red spider lily and another famous ornamental flower known as “Surprise Lily” or “Magic Lily”, also called iron color arrow.

The surprise lily and red spider lily look very similar, but their blooming periods and meanings are different. The surprise lily’s flower language is happiness, joy, and surprise.

They usually open on summer or autumn nights, from June to October, filling the air with a delightful fragrance, hence its nickname “Beauty under the Moon”.
