The special flower for September according to the British Florist Association is
the aster.
The aster, says Interflora, represents both love and daintiness. The flowers are also associated with wisdom, valour and faith, making them a great choice for dear friends and family members.
Reminiscent of a daisy, the aster is named after the Greek word for ‘star’ and, if you look at the shape of the flower, it’s clear to see why.
These delightful flowers bloom all year round and are one of the most vibrant in the autumn months.

I adore asters but we never seem to have much luck with them – they always get eaten by slugs!
Oh those dastardly slugs!
I love this post! I didn’t know all of that about the aster!
Thank you. I didn’t know much about the language of flowers until I started writing these posts. Now I’m hooked. 🌸🌺🌼
You jogged my memory for a book- have you read a book called The Language of Flowers by Vanessa Diffenbaugh? 🌺
I’ve not come across it but googling, it looks very interesting. I’ll look out for it. 🌸
