Description

Dahlia Rosella is used where Irish gardeners want a confident rose pink dahlia that carries through mid summer into autumn. The colour sits well in both cottage borders and more designed planting, and it is commonly used to link pink palettes that include roses, hardy geraniums and soft pastel perennials. Horticulturists also favour rose pink dahlias for customer friendly planting in hotel planters and public facing beds because the colour reads as warm and inviting without looking harsh. Rosella performs well as a feature plant or planted in small groups for a clear block of colour. It also suits large patio containers, where the flowers can be enjoyed close up and care can be controlled. For cutting gardens it provides repeat stems, and regular cutting or deadheading drives ongoing bud production. It performs reliably in wind-exposed rural plots, adapting well once established and tolerating the cooler, wetter spells typical of the Irish climate. Pollinators such as butterflies are frequently drawn to this variety, enhancing biodiversity and supporting local ecosystems throughout the growing season. This cultivar pairs effectively with long-flowering perennials, ornamental grasses and pollinator-friendly companions, making it a versatile choice for cottage gardens, herbaceous borders and naturalistic planting designs.  Plant after frost risk in full sun and fertile, free draining soil improved with compost. Keep moisture steady, pinch early tips for branching if desired, stake in exposed sites, feed from bud stage onwards and deadhead regularly. Lift and store tubers frost free after the first frosts.
