As summer fades into early fall, September brings a softer, slower energy — and the perfect opportunity to send flowers that feel warm, thoughtful, and seasonal.
Whether you’re celebrating a birthday, saying thanks to a teacher, or simply bringing beauty into someone’s day, here’s your guide to the best flowers to send in September.

September Birthdays: Aster & Morning Glory
September’s birth flowers are aster and morning glory — both symbolic, delicate, and beautifully expressive.
- Aster: A symbol of love, wisdom, and elegance
- Morning Glory: Associated with affection and renewal
They pair beautifully with other September favorites like dahlias, lisianthus, and garden roses, creating lush, personal arrangements perfect for birthday gifting.

Back-to-School & Teacher Appreciation Bouquets
The first few weeks of September are filled with transitions — and your favorite teachers deserve a little floral love. Gifting flowers at the start of the school year is a beautiful way to say:
- “Thank you”
- “Welcome back”
- “You’re appreciated”
Go-to flowers for teachers:
- Sunflowers
- Alstroemeria
- Soft-toned roses
- Gerbera daisies
- Petite seasonal mixes wrapped in kraft paper
Pro tip: Pair your bouquet with a handwritten card for an extra thoughtful touch.

Just-Because Arrangements for Early Fall
Some of the best flowers are the ones sent with no special reason at all. September is the perfect time to:
- Brighten someone’s week
- Celebrate a small win
- Show up for someone in a season of change
Our designer’s choice arrangements in soft rust, gold, blush, and peach tones reflect the season without being too “autumn-y.”

Early Fall Sympathy or Support Bouquets
If someone in your life is going through a difficult moment, a September bouquet in muted tones can speak volumes.
We recommend:
- Cream or ivory roses
- Dusty pink lisianthus
- Eucalyptus and textural fillers
- Subtle pops of lavender or mauve
Every order comes with the option for a handwritten note — because softness matters.
