How do I Create a Bush?

Well , I dont know if I can ask questions like this here but I’ve been working on a environment for portfolio because I LOVE environments, Trees plants bushes everything.
But I just cannot think about a good way to create plants like this:

I have no idea how to set-up my (bilboard) planes to make it look like this.

Anyone has some suggestions?

Thanks in advance.

Put in a plane with the bush texture and choose a material with a transparent shader.
Then add a script that makes the bosh turn towards the camera at all times. It’s probably a bit too rough, but it’s a starting point.

Here’s an example (C#):

using UnityEngine;
using System.Collections;

[ExecuteInEditMode]
public class LookAtObject : MonoBehaviour {
	
	public Transform lookAtObject;
	public Vector3 rotationOffset;
	
	// Use this for initialization
	void Start () {
	
	}
	
	// Update is called once per frame
	void Update () {
		if (lookAtObject != null)
		{
			transform.LookAt(lookAtObject);
			transform.Rotate(rotationOffset, Space.Self);
		}
	}
}
