Dahlia 'Bishop of Llandaff'
£4.69
Unit price perEstimated Delivery between January 10 and January 12.
Dahlia 'Bishop of Llandaff' is loved for the contrast of bright red flowers against very dark foliage. It’s a classic choice for cottage borders and cutting beds, and it flowers from summer into autumn. This variety also carries the RHS Award of Garden Merit.
For best results, start tubers in pots from March or April in a frost-free place, then plant out once the risk of frost has passed. Choose full sun and a warm, sheltered position, and mix in plenty of garden compost to improve structure and drainage.
Plant tubers about 10–15cm deep with the ‘eye’ facing upwards, spacing plants roughly 45–60cm apart. Keep the soil evenly moist as shoots develop. If you’re growing taller stems or larger flower heads, add a cane early so support is in place before flowering.
Water deeply in dry weather and feed every two to three weeks through summer with a high-potash fertiliser to encourage buds. Deadhead regularly and cut stems often—removing spent blooms helps direct energy into new flowers, giving you a longer, heavier display.
After the first frosts blacken the foliage, cut stems back and lift the tubers to store somewhere cool, dry and frost-free. In very mild areas you can mulch heavily, but lifting is safest. Replant next spring and you’ll usually see stronger plants each year.

The bulbs arrived beautifully packaged and you could just tell they were excellent quality. We had the most wonderful display of daffodils this spring on our patio. Simply stunning. Will definitely be ordering again

I ordered the mixed hyacinth collection and the scent in my garden this April was absolutely heavenly. Every single bulb produced a strong, beautiful flower and the colours were stunning together. A fantastic purchase, I'll be back for more next year!
