The garden may not have been tended in over 300 years but that didn't mean the plants stopped growing. If anything, the chaotic nature and lack of carefully-weeded rows make it look more verdant. It's a large clearing, with regular mounds beneath the plants that might have once been raised garden beds.
There are some large white flower bunches, and smaller white and purple and red flower of different types. Lots of plants with large leaves sprawling everywhere, some of which have yellow flowers.
What was once a path through the center of the garden has mostly been taken over by a low plant spreading out horizontally with hundreds of runner roots, growing reddish fruit-like objects covered in seeds.
A number of vines cling to the walls. A few have bean pods hanging off of them. Others have flowers and tiny red berries. The decorative hedge has devolved into chaos, growing small dark fruit.
