It is a tufted perennial herb with narrow, channelled, linear leaves and between two and twenty large, drooping, bell-shaped flowers.

It is one of four species of Blandfordia known as Christmas bells, this one growing on the coast and nearby ranges between Sydney in New South Wales and Fraser Island in Queensland.Blandfordia grandiflora is a tufted perennial plant with flat, linear, channelled leaves usually up to 80 cm (31 in) long and 7 mm (0.28 in) wide.

[8]: 45 This species of Christmas bells grows in damp soils on the coast and tablelands between the Hawkesbury River in New South Wales, Fraser Island in Queensland and inland as far as Glen Innes.

[2][9] Although Blandfordia grandiflora is endemic to Australia, in the nineteenth century many botanists grew it in Great Britain because it can easily be grown as a potted plant.

The wet coastal heaths of Australia, such as those found in New South Wales and Queensland, have the sandy soil necessary for it to grow.
