Quick answer: September's primary birth flower is the aster (Aster species), the star-shaped late-summer bloom symbolizing love, wisdom, faith, patience, and elegance. The name "aster" comes from the Greek word for "star." The secondary September birth flower is the morning glory (Ipomoea), a fast-growing climbing vine whose trumpet-shaped flowers open at dawn and close by afternoon — each individual bloom lasts only one day. Morning glories represent love, affection, fleeting beauty, and life's impermanence. The aster is the 20th wedding anniversary flower. September's birthstone is the sapphire. September spans two zodiac signs: Virgo (Aug 23–Sep 22) and Libra (Sep 23–Oct 22). Important safety note: Morning glory seeds contain hallucinogenic compounds and the plant is toxic.
Meet September's Birth Flowers
September is the threshold month — summer's last warmth giving way to autumn's first chill. September's birth flowers reflect this transition perfectly: one blooms when most others have faded, representing enduring strength; the other opens for just a few hours each morning, representing the precious brevity of beautiful moments. Few flower pairings capture the meditative quality of early autumn as well.
The aster (Aster species) is September's primary birth flower — daisy-like, star-shaped blooms in purple, blue, pink, white, and red that emerge when most summer flowers have faded. The name aster comes directly from the Greek word for "star" — and one glance at the flower explains why. Slender ray petals radiate from a golden central disc, creating a perfect star shape. There are between 250 and 350 aster species worldwide, all members of the daisy family (Asteraceae) — the same family that includes sunflowers, dahlias, and chrysanthemums.
The morning glory (Ipomoea species) is September's secondary birth flower — a fast-growing climbing vine producing trumpet-shaped flowers in blue, purple, pink, red, and white. Each individual flower opens at dawn, closes by afternoon, and lasts only one single day. A healthy vine compensates by producing dozens of new blooms each morning. The genus Ipomoea contains over 1,000 species, including the sweet potato (yes, sweet potatoes and morning glories are botanical cousins, with the same characteristic heart-shaped leaves).
Aster Meaning & Symbolism
The aster's symbolism is rooted in its star-shaped form — a flower that brings stardust down to earth. Across cultures and centuries, asters have consistently represented:
- Love and wisdom — the dual core aster meaning
- Patience and elegance — Victorian floriography qualities
- Faith and trust — modern symbolism for steady devotion
- Daintiness and refinement — Victorian "delicate love" interpretation
- Memory and remembrance — French WWII tradition of placing on graves
- Purity and innocence — particularly white asters
- "I won't forget you" — Japanese hanakotoba meaning for shion (purple aster)
- Strength and resilience — blooming when other flowers fade
- 20th wedding anniversary — official anniversary flower for two decades together
"Star" — The Greek Etymology
The word "aster" comes from the ancient Greek αστηρ (aster), meaning "star." The flower's star-shaped appearance with petals radiating like sunbeams from a central golden disc gave it this name thousands of years ago. The Latin form astrum survives in modern English words including astronomy, asteroid, astronaut, and asterisk. Few flower names have spawned such a rich linguistic legacy.
Aster Mythology & Folklore
⭐ Astraea, the Starry Maiden
The most enduring aster myth centers on Astraea, the Greek goddess of innocence and justice — sometimes called the "Starry Maiden." Astraea was the last of the immortals to leave the earth at the end of the Golden Age, returning to the heavens to become the constellation Virgo. According to legend, Astraea looked down from the heavens one night and wept when she saw that the Earth had no stars. Her tears fell to earth and transformed into asters — star-shaped flowers that became earthly constellations scattered across meadows and hillsides. This story directly connects the aster to its name and explains why asters are sometimes called "earth stars."
🐍 Snake-Repelling Incense (Ancient Greece & Rome)
In ancient Greek and Roman cultures, the burning of aster leaves was believed to scare away snakes and ward off evil spirits. Greek and Roman households would burn dried aster leaves as protective incense — particularly during religious ceremonies and in newly built homes. This protective tradition gave asters a sacred status; they were considered offerings worthy of the gods and were placed on altars to Venus (Roman goddess of love) and other deities.
💕 Romans & Venus's Love Potions
Roman tradition associated asters with Venus, the goddess of love. Roman herbalists incorporated aster petals into love potions and aphrodisiac preparations. Carrying a few aster petals was believed to attract romantic attention. This Roman tradition spread into medieval European folk magic — French romantics into the 19th century still concocted love charms from aster leaves.
🇭🇺 The Aster Revolution of 1918
On October 31, 1918, in Budapest, Hungary, protesters demanding independence from the Austro-Hungarian Empire wore asters on their hats as their political symbol. The flowers represented hope, peaceful resistance, and the desire for a new beginning. The peaceful revolution succeeded, and the event came to be known as the "Aster Revolution" — one of the few political events in history named after a flower. The Hungarian First Republic was established weeks later.
🪦 French WWII Grave Tradition
In France following World War II, it became customary to lay asters on the graves of fallen soldiers — particularly French soldiers killed during the war. The asters carried the message "things might have been different" — a quiet floral acknowledgment of loss and what was sacrificed. This tradition extends the aster's meaning into the realm of remembrance and honors, similar to the poppy in Anglo traditions.
🌸 Japanese Hanakotoba — "I Won't Forget You"
In Japanese hanakotoba (the language of flowers), the purple aster is called shion (紫苑). Its specific message is: "I won't forget you." This makes the Japanese aster a particularly meaningful flower for memorial occasions, expressions of lasting love, or messages to friends or family who are far away. The Japanese tradition extends the aster's "remembrance" symbolism into deeply personal emotional connection.
Michaelmas Daisy & St. Michael's Day
In the United Kingdom, native aster species are called "Michaelmas Daisies" because they bloom around St. Michael's Day (September 29) — the feast day of the Archangel Michael. The flowers became associated with this religious feast and remain part of British harvest-time and autumnal celebrations. Michaelmas marks the end of the harvest year in traditional British agriculture, making the aster a natural transition-time flower.
Thomas Jefferson's Monticello Asters
Thomas Jefferson, third President of the United States, grew China asters (Callistephus chinensis) at his Monticello estate in Virginia. Jefferson was an avid gardener and kept meticulous records of his plantings. His preference for China asters helped popularize them in American gardens. China asters are technically a different genus (Callistephus) than European asters (Aster) but share the same star-shape and symbolic meaning.
Chinese Traditional Medicine — Zǐ Wǎn
In Chinese traditional medicine, the aster is called zǐ wǎn (紫菀) and has been used for centuries to treat respiratory conditions, high blood pressure, inflammation, sciatica, and stomach ailments. Some modern research has investigated active compounds in aster extracts, though clinical applications remain in early stages. The plant's medicinal heritage adds practical depth to its symbolic significance.
Aster Colors & What Each Means
Purple Aster
The classic aster color. Symbolizes wisdom, admiration, royalty, and spiritual depth. Most popular color for traditional gifts. Japanese "shion" = "I won't forget you."
White Aster
Innocence, purity, new beginnings. Ideal for weddings, baptisms, and celebrations of fresh starts. Also used for sympathy bouquets.

Monarch Butterfly Migration & Asters
Beyond their symbolic meaning, asters serve a critical ecological role. They are one of the most important late-season nectar sources for monarch butterflies during their fall migration to Mexico. Asters bloom precisely when monarchs need fuel for their long journey south. Planting asters supports butterfly conservation — making them a meaningful flower for environmentally-conscious gardeners.
Morning Glory Meaning & Symbolism
Where the aster's symbolism is rooted in stability and endurance, the morning glory's meaning is built on the opposite: impermanence and the precious brevity of beautiful moments. Morning glory symbolism includes:
- Love and affection — the core romantic meaning
- Fleeting beauty — the most distinctive morning glory meaning
- Renewal and new beginnings — daily resurrection at dawn
- Unrequited love — the Victorian interpretation (love that returns each morning but fades)
- Undying love — the modern positive interpretation
- Mortality and impermanence — Japanese mono no aware connection
- Spiritual aspiration — climbing toward the light
- Seizing the day — carpe diem reminder
- Devotion that renews — coming back each morning
Morning Glory's Cultural & Mythological History
Aztec Sacred Ritual Plant
Morning glories are native to Mexico and Central America, where they were used by the Aztecs and other pre-Columbian Mesoamerican cultures in sacred religious rituals. The Aztecs valued morning glory seeds for their psychoactive properties (some morning glory species contain naturally occurring compounds similar to LSD). The seeds were used by priests in shamanic ceremonies to induce visions. This sacred history gave morning glories deep spiritual significance among indigenous peoples of the Americas long before European introduction.
Japanese Asagao — Morning Face
Morning glories arrived in Japan over 1,000 years ago and quickly became culturally central. The Japanese name is "asagao" (朝顔) — literally meaning "morning face." Japan hosts the annual Morning Glory Festival in Tokyo each July, celebrating these brief, beautiful blooms. The flower became closely connected to the Japanese aesthetic of "mono no aware" (物の哀れ) — the gentle sadness of things passing, the bittersweet beauty of impermanence. Few flowers embody this concept as perfectly as the morning glory.
Hopi Native American Spiritual Messengers
For the Hopi people and other Native American tribes of the southwestern United States, morning glories embody spirituality and act as messengers between the physical and spiritual realms. Their daily blooming and fading cycle symbolizes the eternal cycle of life, death, and rebirth. Some Hopi ceremonies incorporated morning glory imagery into ritual practices honoring the daily cycle of the sun.
Victorian Floriography — Unrequited Love
In Victorian English flower language, morning glories were primarily associated with unrequited love. The reasoning was poetic: the flower opens with hope each morning but withers by afternoon — like love that returns daily but is never fully received. Victorians sometimes sent morning glories to communicate "my love returns each day but goes unanswered." Modern interpretations have shifted toward the more positive "undying love" meaning, but the Victorian melancholy still echoes in the flower's symbolism.
Yellowstone's Morning Glory Pool
The Morning Glory Pool in Yellowstone National Park's upper geyser basin was named in the 1880s for its remarkable resemblance to the flower. The pool's blue-and-yellow coloration — created by thermophilic bacteria — mirrors the morning glory's typical hues. Over the decades, the pool's colors have shifted due to people throwing objects into it (now strictly prohibited), but the name endures as a tribute to the flower's iconic visual identity.
Georgia O'Keeffe's "Blue Morning Glories" (1935)
The pioneering American artist Georgia O'Keeffe, known for her dramatic close-up flower paintings, created one of her most celebrated works "Blue Morning Glories" in 1935. The painting features magnified blue morning glory blooms in O'Keeffe's signature abstract style. The work cemented morning glories in modern American art history and remains one of her most reproduced floral paintings.

Growing Guide — Asters
- Plant in spring after last frost. Asters are perennials that establish best in spring. Container-grown plants can also be planted in fall.
- Choose full sun. Asters need at least 6 hours direct sunlight daily for best flowering. They tolerate light afternoon shade.
- Use well-drained, fertile soil. Add compost when planting. Slightly acidic to neutral pH preferred.
- Space appropriately. Plant 1-3 feet apart depending on variety. Tall asters need more space.
- Water deeply but moderately. About 1 inch per week. Avoid wetting foliage to prevent mildew.
- Pinch back in early summer. Pinch tips of stems in June to encourage bushier growth and more blooms.
- Stake tall varieties. Some asters reach 5-6 feet and may need staking.
- Deadhead spent blooms. Remove faded flowers to extend blooming season and prevent unwanted self-seeding.
- Divide every 2-3 years. Asters spread aggressively. Divide clumps in early spring to maintain vigor.
- Cut for vase at 45-degree angle. Remove lower leaves to keep vase water clean.
Growing Guide — Morning Glories
- Soak seeds overnight before planting. Morning glory seeds have hard coats. Nick seeds with a file or soak overnight in warm water.
- Plant after last frost. Morning glories are annuals (in most climates) that need warm soil to germinate.
- Choose full sun. Morning glories need at least 6 hours direct sunlight daily for prolific blooming.
- Provide climbing support. Install trellises, fences, arbors, or strings BEFORE planting. Morning glories climb up to 12 feet.
- Use well-drained soil. Morning glories tolerate poor soil — actually bloom more in less-fertilized conditions.
- Plant seeds 1/4 inch deep. Space seeds 6-12 inches apart along support structure.
- Water moderately. Once established, morning glories are drought-tolerant. Over-watering reduces blooming.
- Don't over-fertilize. Too much nitrogen produces lush foliage but few flowers.
- Allow self-seeding (or don't). Morning glories readily self-seed — collect seed pods to control spread or plan for reseeding.
- Wear gloves when handling seeds. Due to toxicity, always wash hands after handling. Keep seeds away from children and pets.

The Hungarian First Republic was established weeks later.
Why do morning glory flowers only last one day?
Each individual morning glory bloom opens at dawn, reaches peak in mid-morning, begins closing in early afternoon, and wilts entirely by evening — lasting only ONE day. A healthy morning glory vine compensates by producing dozens of new blooms each morning. This brief lifespan is what makes morning glory the perfect symbol of impermanence and the beauty of fleeting moments.
Why is morning glory called "asagao" in Japan?
"Asagao" (朝顔) means "morning face" in Japanese. The name perfectly captures the flower's habit of opening with sunrise and closing by afternoon. Japan has cultivated morning glories for over 1,000 years. The flower is closely connected to the Japanese aesthetic "mono no aware" (物の哀れ) — the gentle sadness of things passing, the bittersweet beauty of impermanence.
Is the aster the 20th anniversary flower?
Yes. The aster is the traditional 20th wedding anniversary flower, marking two decades of marriage.

What does the Japanese "shion" mean?
"Shion" (紫苑) is the Japanese name for purple aster in the language of flowers (hanakotoba). Its specific message is "I won't forget you."
