I have a Den kingianum 'Gordon's Red' in full bloom.
The spike was well developed in mid August, first bloom opened 4 September.
One of my delicatum plants is in bloom too so its definitely the time for blooms down here.
I live in Victor Harbor, South Australia
The climate is near identical, but the seasons are reversed. Kinganium and nobile have no indication of blooming any time soon, it's just the patricia.
