When applying bonemeal to the ground, the new types of flowers in 1.7 aren't spawning. Only the dandelian and poppy flowers are spawning along with grass.

Also note that the new flowers will only grow in their respective biomes. In other words, if a flower does not naturally appear in a certain area, using bonemeal on dirt will not make it grow.
Unable to reproduce. Is this occurring in a brand new world, or a world from an older version upgraded to 1.7 ?
