I offered to send flowers to apologize but he said not to bother. 

Smoked glass, stained glass, flowers, clouds, etc.

To me, some of this stuff is common sense, but apparently that's a flower that doesn't grow in everybody's garden....Especially when it comes to sharing a bathroom- if you have 2 full bathrooms I would keep a bathroom for myself and let the tenants share a 2nd bathroom between them, especially if you think things not being clean would bother you in the slightest.

Because his landlord, who leaves near by, is mad at him because something happened to her flowers.

Flower boxes, a light wood color.

We are currently redoing the entire house; flooring, bathrooms, kitchen cabinets, removing Luna walls and sheetrocking, removed a bunch of unnecessary walls to open floor plan up, new doors and trim, new furnace, waterlines, water heater, lots of new wiring and lighting, pine T&G walls in dining room, insulated attic and a ton of landscaping (mostly tree, brush and flower removal).

Flowers and green grass everywhere.

What utilities (water,gas,electric) should my tenant pay and what about garbage pick up and gardening (mowing flowers)

A flower doesn't bloom in the shade, surround yourself with like minded individuals, real estate or not and see how far you can get.
