Phalaenopsis schilleriana TKB I have looked at the flowers and they arent any better than any of the other cultivars. TKB im guessing is the cultivar. What makes a cultivar is an award for the flower and then you have the right to name the cultivar of the plant. Bec its a 'TKB' doesnt mean its going to be a better flower than any other schilleriana or cultivar.
The blooms do last for months and brooke yours look wonderful as my schilleriana look like poo as many others Ive seen. Great smelling flower. Light honey scent.
I will say bec you are asking for advice on an expensive plant. You might try a run of the mill plant for test run. An expensive plant doesnt mean you are going to get high dollar flowers from it. So dont be conned into an expensive plant thinking its going to have great looking flowers for everyone who buys one. Just my experience its not going to happen...
