I was playing on a server with the 14w17a Snapshot and noticed that when I hit a Rosebush it would send out lilac particles. I tried it later in creative and noticed that if you are facing EAST and hitting the top block of any two block tall flower they will send out lilac particles, while facing NORTH the particles will be green and while facing SOUTH and WEST they will be gray.

Two in height-flowers that are hit on the lower block will show the top of a sunflower before they "break".

What I expected to happen was...:
Red particles from a rosebush.

What actually happened was...:
Instead it came lilac particles.

Steps to Reproduce:
1. Put a two block tall flower on grass
2.1. Hit top block while facing EAST to get lilac particles
2.2. Hit top block while facing SOUTH and WEST to get gray particles
3. Hit lower block to see a sunflower pop up.
