There was courtyard patio in the center of the building, and tenants could request to have planters assigned to them, so they could plant veggies or flowers, etc. 

Does it have curb appeal (nice flowers / landscaping, mulched flower beds, etc), Are the amenities like screens and fences clean and looking good - no mold, rust, etc?  

Also I would consider raised beds, they are slightly more temporary, and can easily be replanted with perennial flowers that are easy to maintain if she vacates and you don't want to continue to offer a garden.

When a tenant asks if they can plant flowers, I'll pay for half of the perennials.

To apply this to flowers; if the profit a prendre was for flowers and the individual had set up a flower shop, and your denying access to the lawn injured that flower shop, you are liable for the damages to that flower shop.The amount of damages you could be on the hook for are wildly fact dependent.

If you leave them in the ground, consider creating a flower bed around them.

We also put out fresh flowers and a high end chocolate bar on each pillow. 

Or be willing to move in it.I'm just thinking you would at minimum get a better price, and maybe even have a bidding war, if the weather is great, and the flowers are in bloom.For what it's worth, I lived in western WA from the bottom to the top, a total of 18 years.  

Cigarette butts tossed carelessly in a flower pot or flower bed have been known to cause major building fires.
