Single-flowered dahlias
Single-flowered dahlias have one simple row of petals. Unlike double varieties with several layers of petals, they have a lighter, more open appearance.
The simple flower structure makes nectar easier to reach for bees, butterflies and other pollinators. Planting these flowers helps support local pollinating insects and biodiversity in your garden.
Frequently asked questions
Does dark foliage mean a dahlia has single flowers?
No. Leaf colour and flower form are separate traits. Check whether the cultivar has an accessible open centre.
Which dahlias suit pollinators?
Choose flowers with accessible centres, as found in many single-flowered varieties. Check flower form and flowering time.
How do I overwinter dahlia tubers?
Dahlias are frost-tender. Prefer frost-free storage and follow the product’s care advice.
