Good flower form and colour on the Australian Native Hybrid. Maybe the label says Den. delicatum. Interesting that the RHS Site does not have a capital D to begin the name. Den. delicatum occurs as a natural hybrid.

For you, Arthur, I have checked the tag. It is Dend Kathryn Banks x kingianum 'speckles'. Very hard to read. I suppose that was the name around 2003.

Just proves that "looks like" doesn't mean much. Registered as Den. Kathking.
