I had seen this plant a few times before day 65, not knowing what it was.
During those few times, it was not flowering or fruiting. Its leaves were definitely banana leaves but it was shorter than banana trees. So, I was a little confused about what plant it was.
I then happened to see its flowers and fruits on day 65 (early autumn in Sydney). The bright pink flowers and fruits were quite eye catching. Finally, I had some search terms to google. The plant turns out to be pink banana or Musa velutina
