I dont think that holliana and brasil look that similar. But i dont grow any of those cultivars.

Carnosa 'Brazil' is a cross of compacta and 'Krimson Princess', I think carnosa 'Holliana' is a cross between 'Krinkle 8' and compacta albomarginated, and I think carnosa 'Marianna' is an albomarginated form of 'Chelsea'.

Thank you so much professor aurorawa:-)

I said it before......you need to write a book. It would be a best seller in the hobby Hoya growers world.
