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

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.

or "decent" and not "it is dark in here"...) ..Mention the new dishwasher, and have some nice flowers on the funky island and the paper work on the unit and maybe a tablet so it looks like it has a purpose....Best of luck..Best of luck..

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.  

Covered patio to sit in the fresh air with some grass and flowers and talk.

The ones I have in my multi-family units are always the ones that go above and beyond taking care of the property doing things like picking up trash, raking leaves, pulling weeds, and planting flowers.

They also get other gifts from time to time, such as: house plant, flower basket, flower bowl, bedding plant, door mat, fireplace log, professional carpet cleaning of traffic areas (for long term tenants every 5 years).We do not do rent concessions.

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. 

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