Dahlia 'Bishop of Llandaff'

Plant details

Dahlia 'Bishop of Llandaff' is one of the best single dahlias available, from which many of the 'Bishop' dahlias have been bred. It has dark bronze green foliage and contrasting bright red, single to semi-double flowers. It flowers its socks off right up until the first frosts, and the single, open nature of its blooms make it attractive to bees. It's perfect for cutting. The Royal Horticultural Society has given it its Award of Garden Merit (AGM).

Grow Dahlia 'Bishop of Llandaff' at the front of a sunny border, in moist but well-drained soil. After the first frost, cut off the top growth, dig up the tuber and leave it to dry for three weeks. Overwinter it in an airy, frost-free place, and replant the following spring. Alternatively, grow dahlias in pots and move them indoors in autumn.

Oh dear, someone told me this variety of dahlia was the one that could be left in over winter and could therefore be classed as a perenial. From your details this does seem to be the case. Is there another on that fits this category, please.

Started with 6 plants in a small border 3 years ago, I arrived at 46 plants this year after dividing in spring. Tubes are kept in a cool dark cellar during the winter, lightly wrapped in newspaper dots. Dividing in march and primary growth in pots. Planting in border april-may. Fantastic display if combined with crocosmilla.
