This is a general rule: if you want to attract more people-- locals, customers, tourists-- make streets green... that is, green 'up' buildings, including walkways, courtyards, paths and passages. Especially in places and small towns that rely on tourism, this is already known; in addition to street trees and flower borders/beds, tourist hot-spots will usually have many, many greened facades. Street greening is simply beautiful. But... these vertical or street gardens must be cultivated and maintained, just as any garden must be cared for.
Street greening in any style is not only beautiful, but it offers ecological advantages and an ambience of higher quality of life. It increases the aesthetic quality and tends to slow the hectic tempo of the passers-by who may pause a while to enjoy the nature. It is a naturally created 'decelerator'! Shop windows are enjoyed more thoroughly, people stop in street cafés longer, the sales volume of shops and eateries increases. In short: street greening can be monetarily advantageous, as well as ecologicaly beneficial!
First, it is useful to 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. To start the greening, annuals are planted in tubs or pots and placed in front of facades; they then climb up on wires, cords, rope, trelliswork, etc., and from there can even climb tensioned wire ropes set up high or on existing electric cables to create green roofs and garlands. Florists/flower shops are often the first to install annuals, the city may provide planters for eventual facade coverage, and municipalities may even promote the use of flower boxes. In subsequent urbanization plans or city center rehabilitations, planting areas/rings can then be created for future greenings. For this, the plants, flowers, trees, and climbers must be correctly determined and cultivated.
