September Birth Flowers: Aster & Morning Glory — Meaning + What to Send

The September birth flowers are the aster and the morning glory. The aster — named for the Greek word for star — symbolizes wisdom, devotion, and patient love. The morning glory, which opens at dawn and closes by afternoon, stands for affection and the beauty of a single fleeting day. Together they make September one of the most quietly romantic birth months in the flower calendar.

The Aster: A Star on a Stem

Daisy-like but finer, asters bloom in purples, lavenders and whites just as summer flowers fade — one of the few stems that peaks in September. The Victorians treated them as a talisman of patience; the Greeks laid them on altars. In arrangements they read as texture and constellation: dozens of small stars scattered through a bouquet. They're also workhorses — 1-2 weeks of vase life, among the best of any fall stem.

The Morning Glory: Beauty That Doesn't Wait

Each bloom lives one day — open at sunrise, furled by afternoon. As a birth flower it carries a gentle message: love the day you're in. Because they're vining and fragile, florists use them sparingly as cut stems; September arrangements usually honor them with soft trumpet-shaped whites and blues instead.

What to Actually Send for a September Birthday

• The classic: purple asters massed with white accents — unmistakably September.
• The seasonal insider pick: dahlias. September is their peak month in NYC — a dahlia-aster mix is the most in-season birthday gift possible.
• The statement: a fall-toned designer's choice built from that morning's 28th Street market haul.

Frequently Asked Questions

What is the September birth flower?

September has two birth flowers: the aster, symbolizing wisdom, love and faith, and the morning glory, symbolizing affection and the fleeting beauty of a single day.

What do asters symbolize?

Asters stand for wisdom, devotion, and patient love. Named for the Greek word for star, they were laid on altars in ancient Greece as offerings — a September bouquet of asters says enduring affection rather than fleeting passion.

What flowers should I send for a September birthday?

Purple asters make the classic September gift — or lean into peak season: September is dahlia month in New York, and a dahlia-and-aster arrangement is the most seasonal birthday flower you can send.

Are asters easy to keep in a vase?

Yes — asters are among the longest-lasting September stems, often 1-2 weeks with fresh water and a stem trim every few days.
