Thread-Leaf Copper Cups
Pileanthus filifolius
Pileanthus filifolius is a little-known jewel of the Western Australian bush, part of a small and beloved genus in the myrtle family that locals and wildflower hunters simply call copper cups, for the way the buds sit like tiny burnished thimbles along the stems before bursting open. It has no recorded history as a food or medicine plant, its value instead lived out in the sandplains and heathlands where it grows, where it has long fed native bees and nectar-seeking insects during the cooler months. In more recent decades it has found a second life among native plant collectors and cut-flower growers, who prize it for the same starry, copper-and-cream blooms that once simply dotted the wild kwongan scrub of the southwest. Its story is less about the kitchen or the medicine chest and more about a quiet corner of Australian flora that rewards anyone willing to look closely.
In tradition.

The tradition we can stand behind has no household remedy for this plant, so we list none. If that changes as the library grows, this page will grow with it.
Safety.
This wildflower is grown for its blooms, not eaten or brewed, and some people find the sap or foliage mildly irritating to the skin.
