Viridi

Nurture a small pot of succulents that grow in real time.
Viridi is a safe haven, a place you can return to for a moment of peace and quiet whenever, and wherever you need it.
While not fully realistic (they're very forgiving), your succulents will require some maintenance and can die from over- or under-watering. Name your favorite plants, give them special care and attention, and they might even flower for you.
Viridi is free to try and comes with your choice of plant assortment. If you think it has a place in your life, you can buy your favorite plants from the in-game nursery for just a few cents a piece. Remember to visit the nursery occasionally for your weekly free seeding!
