I think it is because of the show of flowers and ease of culture. Phals in my opinion are great because they seem to be easy and there blooms last so long at lease the longest for me. I love my Catt's because there showy but the blooms don't last as long and they smell nice or at least some do.
I have yet to try Bulbo's but am going to. I love there weird blooms but I will say that I'm not sure I want ones that smell like rotting meat. That could be one reason why people don't grow them as much. And I don't know but are they harder to grow? I'm just learning.
It's strange what one person likes another doesn't. It makes us all individuals, even though they want us all to be the same. I don't think we are suppose to be it is what makes the World wonderful to me
