AusBonsai

Purchased as tube stock in the Sumer of 2021.

The label reads, 3-5 metres high x 2-3 metres wide. Hardy. Full sun/part shade. Moist or dry soils. Abundant yellow flowers in spring. Tolerates -7 degrees C. May sucker. Low maintenance.

Sounds like it might have a chance as Bonsai material...

Winter 2021 soft tips trimmed and put into propagator in shade house fish tank. Still sitting up a month later so hopeful of striking, fingers crossed.
2021-10-28 - took image of plant so far. It has been tip pruned and tips have been treated with hormone powder and placed in propagator to strike (if they will). 2021-12-28- Repotted, nipped out the tips of the new growth, bent the trunk a bit.
2021-12-30 Tips pruned again, growing well.

2022-04-27 Putting on new growth after yet another trim.

So far, so good

May sucker.

Comes up several metres away from the original plant in the garden here and then just keeps on going.

Unfortunately does not seem to ever grow a thick trunk. More shrubby with lots of thin trunks. Nice narrow phylodes though and plenty of flowers.
I'll be interested to see how it grows for you in a pot.

2022-04-27 The plant was tip pruned again, and tips were treated with hormone powder and placed in propagator to strike (if they will).

The cuttings are looking promising but I will not transplant until I see roots or new growth (Spring?)....
