Non-chlorophyll-based plants are fascinating. I remember the first time I found Indian Pipes growing in the woods in northern Minnesota. The one pictured to the right is new to me.
Candystick, like the coralroot, has no chlorophyll; it can't make food from sunlight like the green plants do. It is a mycoheterotroph. (Myco = fungus, hetero = other, different, troph = feeding.) It gets its food from an association with a mushroom that in turn, is attached to the root of a green plant.
