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, there are also many, many greened facades. Street greening is simply beautiful! But...it must be cared for and cultivated, just as a wall garden must be cared for.
Street greening in any style is not only more beautiful, it also offers ecological advantages. Moreover, 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! Shops 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 up, such as some of the German "Rosenstädte" ("Rose Cities"). You will find examples below. To start the greening, annuals are planted in tubs or buckets, placed on facades/walls; they then climb up on wires, cords, rope, trelliswork, etc., and maybe even climb high tension greening cables or wires set up high or on existing electric cables. Often, flower shops start to green up with flower boxes on the facades. Municipalities will even promote this. For later street renovations and city center rehabilitations, the “right” plants, flowers, trees, and climbers must be correctly determined, established and cultivated.
