U should.send.pics.to sam. Sam's Choice is supposed to be Rex x Mont Millais, and you can see the Rex in the flower in the first pic. The plant in the second pic is all you could desire from a second generation MM. A special plant indeed.
I've sent a photo to Sam of the 'Lilimo'. He said it's the best one he has seen of this cross by now, and he thinks (me too) that it will improve in size and flower count next time. New growths are on the way to be bigger than the first one... maybe a new bloom in a year
2nd bloom one year later seems to be very difficult with rothschildianum. Not impossible but difficult. Of course, it depends of the 2nd growth size during the 1st bloom.
I had never seen that at home, even with my fast grower rothschildianums.
In my mind, it becomes possible with mature plants.
But if it blooms next year, it's definitely a wonderful clone. So, I'm the 1st on the division list!
