I think  bushie is talking about Banksia ROSES. They are not native.

Banksia Roses will strike from cuttings.  Use a long trough or tray and take cuttings as long a possible with as many leaf nodes as you can get.

Put it on top of the potting mix and peg it to the mix (I just use clothes pegs) to keep the nodes in contact with the mix.  Keep damp but not wet.

They can be slow but they will strike eventually.  Once you have a few plants that have taken, cut the original long cutting to free them up and repot individually.

Thanks Lyndal .... What is the best time of the yr to do this pls?  Whereis the best place to put them ie shade house, hot house etc

Gosh I had both the white and yellow banksia rose.....grew like weeds. Chop off a bit of old wood stick in the ground and presto new plant.

Looks like it's going to be easy to strike them, great 🙂  I don't really need any more, I have plenty, but a cpl of friends have asked me to strike some for them if I can 🙂  Not keen on the white ones, find 'em a tad boring 🙂
