Grevilleas are family Proteaceae plants that are often confused with hakeas. As a general rule of thumb, grevilleas have flowers at the end of the shoot (terminal), and have papery seed capsules instead of hard nuts.
There are only two grevilleas in Foxes Lair., but several hakeas.
Grevillea tenuiflora/Tassel grevillea is a beautiful but atypical grevillea with narrow clustered flowers and a mildly rude pistil.
It has unusual and stunning flowers that remind me of a picture of marine spoon worms that my daughter sent from Korea. Koreans call them gaebul (penis fish), and consume them with relish to enhance their (ahem) vigour. Without claiming efficacy, I recommend a stroll on the Banksia walk in September to see masses of the flowers. Latin scholars amongst you know that tenuiflora is a taxonomist’s way of saying ‘narrow flower’.
