Bright Summer Colour with Pollinator Value

Dahlia Collarette Festivo is a single, open-flowered dahlia selected for its accessible blooms, vibrant colour and strong value to pollinators. Flowering from midsummer through to the first frosts, it produces bold, eye-catching flowers with a clearly exposed central disc, surrounded by a contrasting collar of shorter petals.

This open collarette form allows bees, hoverflies and butterflies easy access to pollen and nectar, making ‘Festivo’ a reliable non-native support plant for extending forage availability during peak summer and into early autumn.

Why We’ve Chosen Dahlia ‘Festivo’

• Pollinator-Accessible Flowers – Open centres make nectar and pollen easy to reach.

• Long Flowering Season – Blooms continuously from July until frost.

• Strong Visual Impact – Bright colours act as a clear signal to insects in busy summer borders.

• Low-Input & Free-Flowering – Performs reliably with simple care and regular deadheading.

• Well Suited to Wildlife Planting – Ideal for mixed borders and pollinator-focused gardens.

Biodiversity-Led Growing Tips

Plant tubers in spring once the risk of frost has passed, in well-drained soil and a sunny position. Regular deadheading will encourage fresh blooms and prolong nectar availability throughout the season.

Leave plants flowering as long as possible into autumn. After the first frost, lift tubers and store them frost-free to ensure strong growth and flowering in future years.
