desert cassia, also known as desert senna or green feathery senna (Senna nemophila), an Australian native that is extremely heat and drought tolerant and hardy to perhaps 10F in dry regions, perhaps 20F in wetter climates.
I do love colour. This grove in the north east ‘goes off’ in spring with Grevillea ‘Moonlight’, Chamelaucium uncinatum ‘CWA Pink’, Anigozanthos ‘Bush Pizazz’, Grevillea ‘Jennifer Joy’, Callistemon spp. and Leptospermum ‘Cardwell’
I am a moron. I have spent 12 months despairing that I had not the funds to build a wooden arbor/trellis for the climbing plants and massive grape vine. This is cheap, strong, and will practically disappear unless you look at it closely.
