#3698 - Cyathostemon heterantherus
Formerly Astartea heteranthera.
At least, I think it's this one - it didn't have a label on it.
Cyathostemon derives from the Greek kyathos (a cup) and stemon (stamen) referring to the cup-like tube formed by the stamens in this genus, and the specific refers to the variable anthers.
It's native to Western Australia, in a long band from the Geraldton Sandplains SE to the Esperance region. It grows in sandy soils over laterite or granite, reaching at best about 2m in height.
Some Astartea are so easy to grow that they are sometimes weedy, but I have no idea if that is the case for this one.
