In the greenhouse/indoors

  • Cyclamen prefer cooler temperatures so sow them anytime between now and March for optimum growth.

Plants outdoors

  • Plant up winter containers with hardy cyclamen, ivy, skimmia and evergreen grasses such as Carex to add colour to your garden. Position them beside entrances and well used paths for a cheerful winter display.
