I,ve got a couple just getting into flowering.
Den Stardust(just the 1 cane @ the moment)

Den Emma Gold.This has 3 spikes but only 2 flowering.

Flowers are about 2 1/2" .
They really are chromatic yellow like the piccie.
First time i,ve bloomed this & i,m really impressed.
I do have a closer piccie of the flowers if anyone is interested.
