Using 1.7.2 flowers in crafting recipes?

[Eria8]

I'm making weapons out of pretty much every material you can find, one of which would be flowers. I need to specifically use Rose, Dandelion and Sunflower but all I can find in Blocks or Items is red_flower, yellow_flower and double_plant. Using those doesn't work. Considering there's no Blocks.flower or Items.flower I assume there's no metadata for them like dyes, so what am I supposed to enter to get the flowers I want to use?

Yeah, I've been there. But that doesn't help, considering there's two options there and three options in the code and none of them match.

So all those flowers are metadata for red_flower and yellow_flower is just the dandelion?
