Product Description
DAHLIA Bishop of Llandaff stands as one of the most celebrated and recognizable garden dahlias, cherished by gardeners for nearly a century. This exceptional peony dahlia combines stunning visual appeal with remarkable garden performance, making it an essential addition to any planting scheme.
Striking Visual Impact
The Bishop of Llandaff dahlia is renowned for its dramatic dark bronze to almost black foliage, which provides an extraordinary backdrop for its brilliant blooms. From July through September, this opulent plant produces striking semi-double, bright vermilion-red flowers measuring 5-6cm across. The intense scarlet-red petals contrast beautifully against the dark foliage, creating a display that has earned it the description as “The best dark-foliage, clear red Dahlia.”
This dahlia was named in 1924 after Bishop Hughes of Llandaff (now Cardiff), Wales, and has remained a garden favourite ever since. The Royal Horticultural Society has recognized its exceptional qualities by awarding it the prestigious Award of Garden Merit (AGM), confirming its outstanding performance and reliability in garden conditions.
Extended Seasonal Interest
Valued for its late summer colour that extends well into autumn, Bishop of Llandaff provides continuous interest when many other plants are fading. The long flowering period makes it ideal for bedding schemes and mixed borders, while the sturdy stems and vibrant blooms make it a popular choice as a cut flower for indoor arrangements.
