Each year the plants finish their spring and summer vegetation by developing fruits, organs which prolong their being in mountains. We know that only special plants we can meet at higher elevation, during our hiking. Most of plants producing fruits grow in sub-alpine zone, in deciduous or coniferous forests. Some others like blueberries can also grow at true alpine level. Many fruits can not be overlooked because of their spectacular colours. Some fruits are very taste and we often consume them when we are very hungry, however, some others are really very poisonous. To eat them or not to eat? You must decide by yourself! However, a general rule "to protect mountain flora" must be treated here as the first of all!!!
