The Parent property of StarterFlower is locked, current parent: NULL, new parent Workspace?

I have this script:

	while wait() do
		local distance = math.floor((player.Character:WaitForChild("HumanoidRootPart").Position - mouse.Hit.p).magnitude)
		if ibreak and distance <= 15 then
			if mouse.Target.Name == "Dirt" or mouse.Target.Name == "Grass" then
			clone.Name = player.Name.."'s plant."
			ibreak = false
			canbeclicked = true
			ClickedButton = false
			MMN()
			break
			   end
			end
		if mouse.Target ~= nil then 
			
		clone.Parent = game.Workspace
		local distance = math.floor((player.Character:WaitForChild("HumanoidRootPart").Position - mouse.Hit.p).magnitude)
		if mouse.Target.Parent.Name ~= script.Parent.Name then
		clone:MoveTo(mouse.Hit.p)
		      end
		   end
		if Canceled then
			clone:Destroy()
			print("Clone's gone!")
			Canceled = false
		end
	end

I get a error everytime when I click to Cancel and to destroy the model that says:
