While most gardeners are looking forward to seeing the leaves changing this season, a few are lucky enough to be in growing zones that have flowers in store for the first of the autumn months!
Many Perennials and a few shrubs rebloom in the fall, often flowering more if you’ve been deadheading religiously throughout the growing season. But either way, you will enjoy loads of blooms in this unlikely time of year!
Keep pollinators well-fed, support hummingbirds throughout their migration, and keep your vase bouquets brimming in blooms with fresh flowers by including these September flowering plants in your landscape!

September Flowering/Reblooming Shrubs
September is high time for reblooming flowering shrubs, and others that just aren’t ready to slow down until frost makes them in cooler climates! Why not have one of these new selections that not only blooms in spring but will also pump out another round of blooms in the new growth at this time of the year? Fantastic idea!

- Spirea (S. japonica and Spirea x bumalda types) are fantastic rebloomers if you take the time to deadhead.
Temperatures and different climates will cause these reblooming plants to vary with their second flush of flowers. Remember to only prune these types of flowering shrubs immediately after they bloom in the spring because waiting too long will result in you taking off the second flush of flowers.
