Unless you want to photograph a plant within the landscape or its environment (plant in foreground with a clear background), photography of plants often means a choise between close-
Plants are satisfying objects to photograph because you can practically find them anywhere (even in the most occupied areas and on the (highest) mountainpeaks) and they are, as it where, standing motionless untill you are ready to make the right shot. Sometimes you can even make use of a reflective screen to ward off the wind and solve low light conditions. One of my favorite subjects are trees. They have a majestic and inaccessible appearance and have a special appeal when they are standing isolated from other trees. Trees are like little ecosystems in themselves, in and around them you will find a variety of animals and plants like insects, birds: reposing, looking for food, singing and nesting, squirels, some species of mice, fungi and mushrooms, ferns, mosses, even wild plants and some trees are even teeming with flowers themselves. This is why trees have a great photographic potential.
Lastly plants determine the environment and thus often the landscape (depending on the soilconditions, region etc), animals either feel at home in this environment or they don't.
