    Cactus dahlias are great because they tend to have large flowers, which are made up of curled 'petals', that give the flower a very showy and quite dramatic appeal.

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

  • 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 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 110m.

  • Dahlia 'Ambition'
    This stunning cactus dahlia is a prolific bloomer, which produces masses of magenta-purple flowers, each up to 15 cm across, for a long period from midsummer. When in flower it will grab centre stage with its jaw-dropping display. It is particularly effective amongst other bruised-toned, summer flowers, or when potted up on a sunny patio. Grows to 90cm.

  • Dahlia 'White Star'
    The creamy white petals of this semi-cactus dahlia are slightly twisted and the tips may have some division, so the overall appearance is spidery and textural. The foliage is a lush shade of green, so this too looks marvellous in the border. Grows to 120cm.

  • Garden care: 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 ‘eyes’ are uppermost. Allow enough room between each tuber so the plants can grow and spread to their full size without being over-crowded. 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.

    Plant spring bulbs

    Spring bulbs, such as daffodils and hyacinths, can be planted whenever the soil conditions allow. As a rough guide, cover them with about twice as much soil as the bulb is deep: so that a 5cm (2in) deep bulb would need a 15cm (6in) deep hole so that it
