Cereus forbesii 'Spiralis' - spiraled cereus & pot cover combination

  • Position: bright but indirect light
  • Soil: specialist cacti compost
  • Rate of growth: slow
  • Hardiness: tender (indoors only)
  • Current height: approximately 20cm (including pot)
  • Pot cover: includes a 10.5cm pot cover

    The upright stem of this unusual cactus forms a twisted column, with 5-9 ribbed edges that are studded with clusters of spines. In time, it will start to branch, forming a candelabra-like effect. Originating from Argentina where it can grow to 4m in height, it's a much more modestly proportioned house plant here in the UK - but no less impressive.

  • Home care: Place it in a bright spot and in spring and summer, water when the compost gets dry, but make sure it never sits in excess water for any length of time. In autumn and winter cut back on the watering but do not let it dry out completely. Avoid a humid atmosphere (no bathrooms or steamy kitchens) and in the warmer months, open a window or door occasionally so it can enjoy the fresh air. Repot every year or two into a slightly larger pot using cacti compost. You will find it easier to tackle if you concertina a couple of sheets of newspaper and then fold these around the spines, leaving a 'tail' that you can use to lift the plant out of one pot and into another. Otherwise invest in some thorn-proof gloves!
