Discolored Dogwood is one of the resources used to create a water filter in Fallout 76. It can be difficult for beginners to find, so the exact location of the plant is listed below.
Discolored dogwood location
It is most often found near the Scout Camp east-northeast of Vault 76 or in the Grafton area, northeast of Vault 76. This does not mean that it cannot be found elsewhere on the map, it is just that these are the only places so far. where it occurs 100%. Also in the Scout Camp there is a blueprint for a water filter, for the creation of which you need a dogwood.
Discolored dogwood grows on trees whose bark is a combination of dark and light spots. Trees can be of different shapes, one of which is the letter "Y".
Note that craft filter is not a very good long-term solution for obtaining purified water. Each filter is suitable for creating 1 unit of purified water, so the amount of resources required is unlikely to justify the ROI. The best solution would be to build a base for mass production.
