Graptophyllum ilicifolium, otherwise known as the Mount Blackwood holly, is a large rainforest shrub which grows in granitic soils.

It has shiny, dark green leaves which resemble those of the unrelated holly, and grows best in moist, semi-shaded, well-drained, well-mulched soils.

The shrub grows to 5 metres in height and has leaves 7.5 to 10 centimetres long which are shiny, noticeably veined, dark green in colour and have a spinous margin.

After identification, the Mount Blackwood holly was propagated and trialled by Society for Growing Australian Plants Mackay Branch members.

It was offered to the general public in 1991 at the Australian Plant Spectacular, then adopted as the floral emblem of the Mackay Branch of the Society for Growing Australian Plants in 1992 and the Mackay Regional Botanic Gardens in 2003.
