I’ve had a zebra grass for 3 years. The first year it grew a little. The second year I moved it to a different location and it was beautiful. However, this year it grew into a totally different ornamental grass. It no longer has any similarities to zebra grass and I am stumped as to why it is no longer a zebra grass. Would you have any ideas as to why this happened. Thank you for your help. My email is: applew8@aol.com
