Dahlia 'Seduction' (Decorative)
Dahlia ‘Seduction’ is an alluring decorative variety known for its elegant pink and purple picotee petals. Each bloom features a pale, milky-white base that is delicately edged with deep violet-pink, creating a defined and sophisticated outline.
The plant is robust and floriferous, producing a high volume of medium-sized flowers throughout the season. The distinct colouring of the petals gives the blooms a three-dimensional quality, making them pop against the dark green foliage.
Plant in full sun to partial shade, in soil that has been improved with compost. This variety is excellent for adding detail and intricacy to a border without overwhelming other plants with solid blocks of colour.
Keep the plant well-watered during dry spells and stake if necessary to support the weight of the flowers. Deadhead faithfully to ensure a display that lasts well into autumn, and protect the tubers from frost during winter.
A brilliant choice for romantic cottage gardens, ‘Seduction’ draws the eye with its intricate detailing and pairs beautifully with deep purple flowers like Salvia ‘Caradonna’ or dark-leaved Heucheras.
