Peonies are such a beautiful flower, but they have a very short growing time and are only available in the early summer months. Luckily, there are a number of alternatives for an autumnal wedding. I'd go for some gorgeous garden roses, which are available all year round and have the same ruffled, fluffy and full look that gives the peony its scrumptious volume. Some varieties are also scented as an added bonus! If you're looking for something with the wow factor when it comes to size, dahlias are the perfect alternative thanks to the impact of that majestic bloom. Best of all, they'll be in season at the time of your wedding. They do tend to come in stronger colours though, so if bright and bold isn't for you, another sizeable flower to consider could be a hydrangea. They have the same lovely roundness and fluffiness and come in pastel hues. Remember to check with your florist, as we always have something up our sleeves to create the look you're after.
