Need Red or Yellow dye?

To add color to our drab creations, dye wool and use it in the construction.  There are a variety of colors and there is a link to the right with ALL minecraft recipes.  The problem is having / finding the ingredients, and red is one of the toughest.
Red flowers, roses, are required to make red dye.  One rose will make 3 red dye. But roses are found in the wild and as far as I can tell, they can not be domesticated.  But, nature can be given a push.  The use of bone meal, made from bones, dropped by skeletons is a fertilizer.  Use some bone meal on a sapling, POW get full grown tree.  Use some meal on a planted seed, POW get full grown wheat.  Use some on a rose, POW get LOTS of tall grass! Hummm.... not what I expected ether, but lots of tall grass looked cool so I did it over and over.  Then, pow, a yellow flower showed up in the tall grass.  So I did again and again, pow, a rose!  Yippee! I grew a rose! Three more red dye in the pocket.
Well, I know Tony needs red dye and lots of it for his castle (oh yea... Tony is building a castle, check it out).  So, I took 3 bones, crafted them into 9 bone meal and ran to Tony's house but he was not home.  So I used the 9 bone meal on the grass in his front yard and managed to grow 7 roses for him!  As well as 10 yellow flowers and lots of tall grass, that I am sure he does not want.

So, the effects are random, but you do get roses, without having to search the world to find them.

 

Oh, by the way Tony, your roof leaks... maybe but a hatch on the roof access.
