Formal Garden

My sons D&D game is now in a Fey palace for a while. A curious thing about this palace is that depending on which door you go out of, it’s a different season. This formal Garden is outside the North door, which is Spring. While it is a formal garden, there is a wild edge to it and curious flora and fauna have been known to inhabit the garden. At the moment, there is a particularly nasty threat in the north east corner trying to turn the garden back into wilderness.

This 300dpi image has 70px squares that should work on any VTT system. The squares are meant to be 10 feet across. While there are clearly laid out paths, most of the green is well manicured lawn. But what happens if you step on the grass?
