September has two birth flowers: the aster and the morning glory. They are an unlikely pair — one a sturdy perennial that holds its color well into fall, the other a climbing vine whose blooms open at dawn and close before noon. If you are looking for September birthday flowers with some meaning behind them, both are worth knowing. This guide covers what each flower symbolizes, how they compare as gift options, and how to find the right bouquet for someone born this month.
Why September Has Two Birth Flowers
The tradition of birth month flowers traces back through Roman customs, Victorian flower language, and regional practices that developed independently over centuries. Because no single tradition set the rules, some months ended up with more than one bloom.
For September, the aster is the primary birth month flower, recognized across most of North America and Europe. The morning glory is the secondary flower — linked to September through its natural bloom window, which runs from early summer through the first weeks of fall.
As a gift flower, the aster is the practical choice: widely available, it holds well as a cut stem, and it carries real symbolic weight. Morning glory is harder to source but speaks to something different — presence, affection, and the particular beauty of things that don’t stay. Knowing what sets them apart makes it easier to choose between them.
Aster: The Star-Shaped Bloom of Late Summer
The name comes from the Greek word for star. Petals fan outward from a tight yellow center the way a starburst does, giving the bloom a clean, structured shape that holds up in arrangements both simple and layered.
Aster flower meaning centers on wisdom, patience, and enduring love. In Victorian flower language, asters were given to express deep admiration. In Japan, the aster carries the message “I won’t forget you” — which lands differently on a birthday than a generic bouquet does.
Color matters here. Purple asters are the most common, associated with wisdom and quiet distinction. Pink reads as warmth and affection — a natural fit for a close friend or partner. White asters are understated: sincere, calm, and suited to almost any relationship.
Asters are also the official 20th anniversary flower, worth keeping in mind as anniversary flowers when that milestone falls in September.
As a cut flower, asters typically last five to seven days. That staying power makes them a reliable choice for birthday flowers when delivery timing is not perfectly controlled — the arrangement still looks good on day three.
Morning Glory: Brief, Bold, and Worth the Moment
Morning glory is a difficult gift flower to source. It grows as a climbing vine rather than a cut stem, its blooms last only a few hours each morning, and it rarely turns up in commercial bouquets. Most florists simply won’t carry it.
What it offers is meaning — and that meaning is specific. Morning glory symbolizes affection, renewal, and the beauty of something that doesn’t ask to be permanent. In Victorian tradition it was linked to love that goes unreturned: not tragic, but honest about its own limits. The flower opens fully and then lets go.
That sentiment travels well without the actual stem. A loose, informal arrangement ordered just because — no occasion attached, no explanation required — carries the same spirit. With morning glory, the gesture matters more than the ingredient.
How to Choose a September Birthday Bouquet
For most September birthdays, asters are the better starting point. They are in season, they hold their shape well in transit, and a color chosen with some thought makes the bouquet feel personal rather than generic.
Purple or lavender asters suit someone thoughtful or quietly creative — the Virgo end of September. Pink asters work for a closer relationship: a friend, a sibling, a partner. White is the right call for a colleague or someone whose taste you are less certain of.
For an arrangement that feels seasonally grounded, asters pair naturally with dahlias — both peak in late summer, and the dahlia’s larger head gives the aster room to add texture without competing. Our mix bouquets follow what is in season, so September arrangements tend to include asters alongside dahlias and similar fall stems.
If you know what the recipient responds to, a single-variety aster arrangement is the more considered choice. If you are less certain, a mixed seasonal bouquet is a sound default.
September Flower Delivery Across the Bay Area
Flowers Valley offers same-day flower delivery throughout the San Francisco Bay Area. Orders placed before noon typically arrive the same afternoon.
Asters stay in stock through the end of September, which means they work for birthdays across the full month — Virgo birthdays in early September and Libra birthdays closer to the end. For arrangements that need to arrive fully open, ordering a day ahead tends to give the best result.
If you are not sure what to write in a note, mentioning that the aster is their birth flower is enough. It is a small detail, but it tends to stay with people.
