After hours and hours I finally got the box saying the garden was finished and the puzzle screen shows that it's complete... but there are no flowers!

When I drop a villager there it says enjoying the garden, so I know it's done but there's nothing there, it still looks the same as before.

Will everything still work with the GC and such without actually being able to see it? Or do I need to start over?

I've restarted my game and my computer and it doesn't help.
