foliage color of canna?
 

Hello,

I've seen photos of durban canna, which range from green to brown to
striped to magenta. Can all of these be the same variety? (They all
have the same name: "durban".) If so, how does a gardener get the
preferred colors of canna foliage? If not, how do I know what I'm
getting when I buy a durban bulb?

Thank you,

Ted Shoemaker
