Viridi

This is a very basic game: the plant models are mirrored and can be pretty simplistic when you really get down to looking at them, sometimes the clicking is a little off and it can be finicky to weed the garden, but ultimately, these things don't keep me from opening the game. I like it. I like naming my plants and "singing" to them. It's a cute game that I have kept visiting for many, many years now off and on; the plants are very forgiving unlike real life.

Simple, yet relaxing. The pacing is real time based and the plants will grow a little each day with some plants taking a longer time to mature than others. There are some micro transactions for extra pots and seeds but you're not forced to buy anything if you don't want to. The seeds are tradeable with other players via steam trades and there's a very helpful seed exchange that can be found in the discussion forums for those trying to get achievements for rarer plants. It's one of those games you're going to find yourself opening either once a day for a few moments or once every so many days to do simple maitnance (weeding, watering, tossing or planting new plants).
