Thujas are very popular in Poland too. They do not grow wild in our forests, they are grown by gardeners for parks, gardens and ... cemeteries. For me, for years it was just cemetary shrub/tree, which separated grave from grave. It has changed and now they are commonly grown as evergreen hedges or in gardens.
Juniperus has lots of varieties too. Besides the gardens, they grow in sunny places in sandy forests. You can find them looking for the mushrooms.
Black dried fruits are used for special kind of dried, smoked saussages or for "wild" roasted meat.
