Holly Barricade is an unused plant added in the 6.3.1 update, and is currently unknown what it is used for. In the v6.3.1 update, it uses Endurian's textures as a place holder, as well as acting like Endurian. Suggesting that it might have been an Endurian upgrade, or at least a defensive melee attacker. Its degrades are also the same. Even though it has a shield to begin with, it does not offer any additional defense and is most likely a bug in the programming. However, it dissappears once the plant reaches the first degrade. In the v6.4.1 update, it used Homing Thistle's textures as a place holder now.
(v6.3.1) Gains a shield. The shield has no degrades and with the shield always on bug, it makes it difficult to tell when the actual shield breaks.
- It is named "hollyknight" in the codes.
