remarks to the plant:
Box is an evergreen, very adaptable and durable shrub or small tree, frequently planted in parks and gardens because of its small, leathery leaves, its dense growth and the fact that it can be trimmed to almost any desired form. If not curbed, the inconspicuous yellowish-green flowers appear between
March and May. Several male florets with eye-catching yellow stamens surround a female floret. A lot of easily accessible nectar attracts bees.
