I am trying out a few Acacias and the Golden Wattle is likely to prove hardy in the south on a sunny and free draining site. This one is the national emblem of Oz. Fragrant flowers in early spring and growing to about 7 metres. 9cm pots. I haven't flowered it yet so image from Melburnian - Own work, CC BY-SA 3.0, https://commons.wikimedia.org/w/index.php?curid=1113638
