After the warmth of the earlier summer months, September brings a change. As autumn edges in, the flowers and plant materials available offer a wealth of seasonal treasures. Some are fleeting – but all deserve their moment in the spotlight.
Here are our experts’ top five cut flowers for September – all standout choices you’ll want to get your hands on this month. They bring colour, texture and oh-so-much interest to your designs.
#1 Amaranthus
One flower that really makes us welcome the changing season is Amaranthus. There’s nothing quite like it. It provides so much interest, natural movement, and amazing texture to any design. It’s the very best time of year to appreciate and get your hands on the wider seasonal selection. Whilst commonly known as love-lies-bleeding, there are now many more varieties than the traditional red trailing type – and we’re not just talking about upright forms.
Below we show just nine different varieties, giving you a glimpse of some bi-colour beauties, upright and semi-upright forms, a range of colour tones, some popular favourites and the funky spider types.
We would ask which is your favourite, but the beauty is you don’t have to choose just one, especially not in September when a wider range is available. They truly deserve their place in the top 5 flowers for September, and we encourage you to enjoy them to the max!

The selection of garden-style roses is quite extraordinary. No longer are we restricted to a handful of varieties, and whilst a wide selection is available throughout the year, some growers will start to reduce their range over the next month or so.
VIP Roses’ production in Holland is available between April and November, whilst Wans Roses, located in Germany, has a main season from March to the end of October.
That’s why we’ve chosen this month to highlight this beautiful range. Before too long, some of the fabulous varieties you can enjoy now will become dormant and unavailable for picking until 2027!
Below we’re showcasing a very small selection from VIP Roses and Wans Roses. Keep reading to discover more new varieties and explore a much greater range.

#3 Veronica
It may not be the largest or most attention-grabbing flower, but Veronica adds a dainty spike form that can bring a design to life.
Having said that, as you can see from the images below, there are now varieties that don’t have the traditional spike form – step forward Smart: Fountain, Splash and Wave.

#4 Dianthus barbatus
Dianthus barbatus is the cousin of the well-known Dianthus, better known as the Carnation, but this barbatus deserves just as much attention – especially in September, when it’s in its seasonal prime.
For many, Sweet Williams provide that nostalgic reminder of childhood, as they’re an archetypal garden flower. But did you know that Dianthus has been cultivated as a garden flower for centuries?
Although they’ve been around for some time, today we have a wide range of commercial varieties, many of them new to the market.
We’ve shared just a small selection of the many varieties available, but have tried to showcase the wonderful range of colours. Sweet Williams are available in white, pink, magenta, red, burgundy, purple and lavender, not to mention a wide selection of bi-colours.
And that’s without taking into consideration the playful all-green Dianthus barbatus varieties, such as ‘Green Trick’, Green Queen, Green Wicky, Lady in Green and Kiwi Cool. The list goes on!
#5 Alstroemeria
How many different varieties do you use?
Once upon a time, when you said ‘Alstroemeria’, you knew exactly what type of variety you’d get… Fast forward to today and we have a range of Alstroemeria the likes of which we couldn’t have imagined 15 years ago.
We’ve showcased a range of varieties from groups including standard, Florinca and specialities, such as the single-headed Fashionista®.
Take a few moments to watch the images scroll through and appreciate just how diverse the range of Alstroemeria now available to us has become.
The name of each variety can be found by hovering over the scrolling images. Alternatively, tap an image to open it in a lightbox, with the variety name shown underneath as you swipe or tap to move to the next.
Obviously, this only shows a fraction of the range available to buy throughout September and the rest of the year.
