I cannot place a lilac in a clay pot.
I can place other flora like ferns, trees, dandelions, but I cannot place lilac in the pot at all.

Works as intended. See Wiki article on the Flower Pot: http://minecraft.gamepedia.com/Flower_Pot
"Plants that can be placed in a pot include any one block high flowers, saplings, mushrooms, and cacti."
You could suggest for it to be added at the minecraftsuggestions on reddit

intended the lilac exists out of 2 blocks, the others don't (btw it's called a flower pot)
