Flowers I like v. flowers that look good

I never really loved chrysanthemums, but they were all that Sainsbury’s had left when I went in there for some flowers the other day.  So I bought a bunch of white chrysanthemums and brought them home, where they look great.  It seems that the flowers I like for themselves are not the same flowers that look good in my egg.

Hmm.

Gerberas

I have some gerberas in a vase in front of my window. I don’t ever buy gerberas, but I was buying flowers for a boy who was staying in my house and they seemed appropriately manly. And you know what? I really, really like them. I might only ever buy gerberas from now on.

Are flower names capitalised? And why do I want the plural of gerbera to be “gerbera”?
