I bought and ready to plant!
The dahlia is named after the 18th century Swedish botanist Anders Dahl, a student of Carl Linnaeus. Around the same time, in Germany, it was also named ‘Georgia’ after the Russian botanist Johann Gottlieb Georgi, and some still know it by this name.
This cultivar was so-named in 1924 to honour Joshua Pritchard Hughes who was the Bishop of Llandaff (a Diocese in South Wales) from 1905 to 1931.
How to grow dahlias:
- Dahlia 'Bishop of Llandaff' (P)
Genus Dahlia are tuberous rooted perennials with pinnately divided leaves and showy flower-heads, double in many cultivars, in summer and autumn. Tender Perennial Tuber.
Family Asteraceae / Asteraceae
Details 'Bishop of Llandaff' is an herbaceous perennial to 1m in height, with deep blackish-red foliage and semi-double brilliant red flowers 6cm in width.
Plant 30cm (12in) deep, 75cm (30in) apart.
Propagation Propagate by softwood cuttings taken in spring from shoots from stored tubers, or divide the tubers ensuring each division has a viable bud.
Cuttings should root within twenty days.
Pruning Deadhead to prolong flowering. Cut back to near ground level in the autumn, before lifting and storing for the winter.
Feed with a potash-rich plant food, either home-made comfrey tea or liquid tomato feed, once buds appear.
Monty Don: Call it a dahlia | Life and style | The Guardian:
Love them or loathe them - even the most fervent anti-dahlia gardener can't resist the Bishop of Llandaff.
The parent plants can be put outside in mid-May, when the risk of frost is past. If you are not going to take cuttings, plant the overwintered tubers out about 15 cm deep in early April, in rich soil in full sunlight. The new shoots appear above ground about a month later.
In most well-drained urban gardens I think it perfectly safe to leave them in the ground over the winter as long as they are cut back to the ground and mulched thickly. But if you are likely to get ground frosts of -5ºC or below, or if you have heavy soil – both of which we have here – I would strongly recommend lifting them after the first frost.
Slugs will graze a scar along the length of the stems as well as eating the foliage, while earwigs are very fond of eating the petals.
The best way to stop earwig damage is to place an empty flowerpot on a cane – ideally the one supporting the dahlia – and stuff it with some torn-up paper or straw; the earwigs will crawl inside during the day, when they can be found and taken away.
In the spring mulch them with some rich organic matter (eg well rotted compost or farmyard manure) and feed them with a general purpose fertiliser when growth begins.(Here!)

Companion Plants: Foeniculum vulgare 'purpureum' Fennel (bronze fennel-) or verbena bonariensis and Dahlia 'Bishop of Llandaff'.
The bronze or purple form of garden fennel (not to be confused with sweet or Florence fennel, an annual vegetable grown for its swollen bulbs) is a handsome and popular perennial, often planted on its own for impact or combined with bergamot in flower borders.
- Paeonia officinalis 'Rubra Plena' (d)

Details- 'Rubra Plena' is a robust herbaceous perennial to 75cm in height, with dark green, divided leaves and fully double rich crimson flowers 15-20cm across.
Planting depth - 3 cm.
Time to maturity: 5-10 years.
