Add a bold splash of sumptuous colour with these gorgeous dahlias. They're noted for their reliable display and good garden performance, which is why they have all been awarded an RHS AGM.

How to care for Award-winning border favourite dahlia collection:

While in growth, provide a high-nitrogen liquid feed each week in June, then a high-potash fertiliser each week from July to September. Stake with canes or brushwood if it becomes necessary. In mild areas, leave them in situ over winter, but protect the crown with a generous layer of dry mulch. In colder areas, carefully lift and clean the tubers once the first frosts have blackened the foliage and allow them to dry naturally indoors. Then place the dry tubers in a shallow tray, just covered with slightly moist potting compost, sand or vermiculite and store in a frost-free place until planting out again.

Planting tips:

Dahlia tubers can be planted outside after frost, or started off in pots under glass in late winter to early spring. Plant them horizontally approximately 12cm deep, making sure the growing points (‘eyes’) are uppermost. Allow enough room between each tuber so the plants can grow and spread to their full size without being overcrowded.

What's included:

In each collection you will receive one tuber of each of the following cultivars:

  • Dahlia 'Bishop of Llandaff': Striking, semi-double, bright vermilion-red flowers appear from July to September above the deeply divided, dark bronze-red leaves. This popular, peony-flowered dahlia requires a sunny site with fertile, humus-rich soil. Perfect for a planting scheme based on 'hot' colours, the tubers must be lifted and over-wintered in a frost-free place in all but the warmest areas. Grows to 1.1m.

  • Dahlia 'David Howard': This miniature, decorative-type dahlia will happily grow at the front of a sheltered border or in a large patio pot. Flourishing in fertile, humus-rich soil, the fully double, soft burnt orange flowers and dramatic, dark purple-bronze leaves are perfect for an exotic-type border or hot planting scheme. Grows to 1m.

  • Dahlia 'Chat Noir': A sumptuous cactus dahlia with garnet red flowers (up to 15cm across), which have a near-black centre. The fully double flowers have long and narrow, pointed petals that recurve for more than half their length. This dahlia looks great planted in bold groups in a sunny, sheltered border or as part of an exotic scheme. The flowers appear from July until the first frosts, and make excellent cut flowers. Grows to 1.1m.
