How can I find the name of the tile that I collided with in 2d?

I’m trying to make a game where you can farm metals. I’m just using the standard tile system where I have 20 tiles. One is grass, the others are metal plants and the seeds for them. Say I want it where if I collide with a bronze plant, I can do something, such as Debug.Log(“Bronze”) for starters? This is all I have for now, it is currently doing nothing when I hit the bronze plant, so not very useful.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class FindPlant : MonoBehaviour
{
    void OnCollisionEnter(Collision col)
    {
        if (col.gameObject.name == "tilemap_1")
        {
             Debug.Log("Bronze");
        }
    }
}

You must have at least one rigidbody attached in order to OnCollisionEnter work. (Source)
