How to code a flower on Minecraft?

I have look at tutorials and wrote a class file however, in game the flower appears to not work. Any help is greatly appreciated. Heres the code and the result;

package ark.dragonmod.plant;

import java.util.Random;

import net.minecraft.block.Block;
import net.minecraft.block.material.Material;
import net.minecraft.client.renderer.texture.Ic…
import net.minecraft.util.AxisAlignedBB;
import net.minecraft.world.World;
import net.minecraftforge.common.EnumPlantType;
import net.minecraftforge.common.IPlantable;
import ark.dragonmod.common.DragonMod;

public class PlantDragonic extends Block implements IPlantable {

public PlantDragonic(int par1, Material par2Material) {
super(par1, par2Material);
this.setCreativeTab(DragonMod.TabDrag…
this.setTickRandomly(true);
}

protected PlantDragonic(int par1)
{
this(par1, Material.plants);
}

@Override
public EnumPlantType getPlantType(World world, int x, int y, int z) {
return null;
}

@Override
public int getPlantID(World world, int x, int y, int z) {
return blockID;
}

@Override
public int getPlantMetadata(World world, int x, int y, int z) {
return 0;
}

public boolean canPlaceBlockAt(World par1World, int par2, int par3, int par4) {
return super.canPlaceBlockAt(par1World, par2, par3, par4) && canBlockStay(par1World, par2, par3, par4);
}
protected boolean canThisPlantGrowOnThisBlockID(int par1) {
return par1 == DragonMod.DirtCharred.blockID;
}

Added (1). @Override
public boolean canBlockStay(World world, int x, int y, int z)
{
int soilBlockID = world.getBlockId(x, y - 1, z);
return (soilBlockID == DragonMod.DirtCharred.blockID || (soilBlockID == Block.dirt.blockID || soilBlockID == Block.grass.blockID. ;
}

public boolean isOpaqueCude() {
return false;
}
public boolean renderAsNormalBlock() {
return false;
}
public int getRenderType() {
return 1;
}

. Can't seem to be able to post the whole class file.

Added (2). public void updateTick(World par1World, int par2, int par3, int par4, Random par5random) {
this.checkFlowerChange(par1World, par2, par3, par4);
}

protected final void checkFlowerChange(World par1World, int par2, int par3, int par4) {
if(!this.canBlockStay(par1World, par2, par3, par4. {
this.dropBlockAsItem(par1World, par2, par3, par4, par1World.getBlockMetadata(par2, par3, par4), 0);
par1World.setBlock(par2, par3, par4, 0, 0, 2);
}
}

Added (3). public void onNeighborBlockChange(World par1World, int par2, int par3, int par4, int par5) {
super.onNeighborBlockChange(par1World… Par2, par3, par4, par5);
this.checkFlowerChange(par1World, par2, par3, par4);
}
public AxisAlignedBB getCollisionBoundingBoxFromPool(World par1World, int i, int j, int k) {
return null;
}
public int idDropped(int par1, Random par2Random, int par3) {
return this.blockID;
}
public int quantityDropped(Random par2Random) {
return 1;
}

Added (4). public void registerIcons(IconRegister iconRegister) {
blockIcon = iconRegister.registerIcon("DragonMod: Dra…
}
}
. That's the rest, sry for the length, wasn't sure how to include the class file.
