Question: I know I could just carry a bottle, but scavenging is much more fun. What is a good source of vitamin C in the wild? Have spruce needles really got enough?

Answer: 
[Pine needle tea](http://www.practicalprimitive.com/skillofthemonth/pineneedletea.html) is a good solution which is available year round in areas where pines grow. Do be careful to identify properly, and take care to not guzzle the stuff down... too much is bad for you. However this is the easiest to find and pine needle tea has a ton of vitamin C.

[Dandelion greens](http://en.wikipedia.org/wiki/Taraxacum#Culinary_use) are plentiful in many areas and good for vitamin C, though I detest the flavor.

[Chicory](http://en.wikipedia.org/wiki/Chicory) is a decent source, though I find it to be too easy to misidentify.
[Scurvy Grass Sorrell](http://en.wikipedia.org/wiki/Oxalis_enneaphylla) has leaves rich in Vitamin C, and got its name from sailors travelling round Cape Horn who would eat the leaves to avoid scurvy.

It tastes pretty good, despite what the Wikipedia page says, but I'm not sure how widespread it is outside South America.
