Green 'up' buildings, walkways, courtyards, paths and passages. This is already well known in small towns that rely on tourism; flowers and foliage along small shop entrances and otherwise uninteresting corners bring unparalleled charm. In addition to street trees and flower beds, tourist hot-spots will usually have many greened facades. Street greening is simply beautiful. Naturally, these vertical or street gardens must be cultivated and maintained, just as any garden must be cared for.
First collect inspiration and ideas from towns which have already successfully greened their streets, such as some of the German "Rosenstädte" ("Rose Cities"). You will find examples below. Usually greening starts with annuals planted in containers and placed near facades; from there they climb on wires, cords, rope, trelliswork, etc., even climbing horizontally on high-set tensioned ropes or on existing electric cables to create green roofs and garlands. Flower shops are often the first to initiate; the city may provide planters for eventual facade coverage, and municipalities may even promote the use of flower boxes. In subsequent urbanisation plans or city centre rehabilitations, planting areas / flower beds can then be created for future greenings. For this, the plants, flowers, trees, and climbers must be correctly determined and cultivated.
Greenery is a well-known feel-good factor, especially in outdoor dining areas. However, heritage protection authorities may intervene if cafés and restaurants green their façades for this reason. The following argument may help: Awnings (see photo below) are often needed for the successful operation of an outdoor seating area. In both cases – wall greening and awnings – the monument is altered, but both must be accepted if the preservation of the monument can only be financed through contemporary use (outdoor dining).
