GameObject not reactivating

I deactivated the object in the inspector (the small check box right next to the name) but this code doesn't reactivate it after a certain amount of time. I am using Unity 2d and C#

 {
 
 
     private Object Flower;
 
     void Start()
     {
         StartCoroutine(flower());
     }
 
     IEnumerator flower()
     {
         print(Time.time);
         yield return new WaitForSeconds(8);
         Instantiate(Flower);
         print(Time.time);
     }
 }
