I thought Zorro is top rated?

Does the Zorro variety look like the Emerald variety and will it be harmful to introduce it in my Emerald stand?

Zeon will work, it is superior to emerald. I place it in spots of my lawn where emerald was troubled and it thrived. It's hard to tell but there is a very subtle difference between the 2. Also zeon has choked over half my yard it took 4 years but it moves laterally faster than emerald.
