The Dilapidated Arboretum is a second level biome that is exclusive to the Bad Seed DLC. Dappled light, soothing fountains and a fresh air brought the royals, aristocratic and various hangers-on to the gardens and serres of the arboretum to escape the hustle and bustle of the castle to have some moments of peace and relaxation.
However, the fragrance of their perfumes had, unbeknownst to them, disturbed the local flora and fauna. Now the arboretum, a shadow of its former glory, attracted a different kind of visitor, who enjoyed the earthy smells of compost, spores and decay very, very much.
General information[]
Access and exit[]
The Arboretum can be accessed from the Prisoners' Quarters via a 
Teleportation Rune after having first accessed the area with the 
Dilapidated Arboretum Key.
There are three exits out of the Arboretum, which consist of the Prison Depths (requiring a Spider rune), the Morass of the Banished, and the Ramparts.

Lore[]
Botanical beaker room[]
The botanical beaker in the middle of the room.
The room depicted in the following picture contains three items that can be examined:
Order[]
A letter written by an unknown person, presumably some sort of guard:
- "Apparently seeing the dead rise wasn't enough.
- "Today it's the plants that are up and raising hell."
- "The King's new best friend has ordered one of them captured... Alive..."
- "...I'd like to see that!"
Botanical beaker[]
A large glass container filled with some sort of rotting corpse.
- "How did they get the skeleton in the bottle?"
Books[]
A stack of books can be found laying nearby.
- "“Man vs Wild” and other botanical treatises are spread out on the ground."
- "I wonder what's in this flask..."
Giant tree room[]
The giant tree with a victim and a broken flask.
Trunk[]
A large tree that appears to have various pieces of flesh and skeletons shoved into a hole in its side.
- "It seems like these infected ones were trapped in the trunk..."
- "Makes you wonder who was the sick one in this story..."
Skull[]
Beside the tree there is a glass container containing a large bird skull.
- "The skull of a giant crow mixed in with various bits of mushed and mashed organs, entrails and local roots..."
- "...connected to the bark of an old red giant tree."
- "The perfect evil wizard starter kit..."
Fancy lounge[]
The fancy lounge.
Luxurious chaise longue[]
A fancy longue with some opened books resting upon it.
- "Varnished wood... satin pillows..."
- "A bunch of leather bound books..."
- "I wonder which noble had their personal garden here."
Chaise longue[]
A rougher longue with some gardening equipment resting beside it.
- "Gloves, a pitchfork... Maybe a courtier tried their hand at gardening?"
- "No, you wouldn't find one that would sit on such a shabby piece of furniture."
- "Or wear this outfit."
- "It seems the gardener had his entrances into the palace too."
Once the Beheaded says, "Or wear this outfit." the 
Gardener's Outfit blueprint will drop.
Yeeter room[]
Pile of dead Yeeters
A room filled with the bodies of Yeeters and a human corpse.
- "By the King's command, you are to burn the entire Arboretum down until nothing is left but cinders."
- "And ignore the gardener's protestations... he is no longer under the Crown's protection."
Research room[]
Research room
A research room with a desk, cabinet and plants. A letter and order from the king can be found.
Letter[]
- "I'm alive again... but I can feel the madness lurking in the shadows. And I don't think these medical plants will help me for long."
King's order[]
- "Yet another order to burn down the Arboretum"
Large water pipe[]
A large room can be found containing a giant water pipe snaking through it.
Scribbled note[]
At the opposite end of the entrance there is a spout attached to the pipe with a warning sign hanging from it.
- "WARNING: DON'T WATER THE PLANTS!"
- ...
- But where does it go?
Notes[]
- It appears that there was some form of experimentation going on within the arboretum that involved using people and animals as a base for the growth of some of the various plants and fungi found within the large glass canisters. Various skeletons can be seen within the soil of certain plants. In the case of the large tree, whole organs and people were attached to it for some sick, unknown purpose.
