|Façade with Wisteria|
In selecting the climbing plants an emphasis was placed on types that can grow in planter boxes under extreme conditions. Of the various plants tested the Wisteria sinensis has proven to do the best. In addition, a special system of irrigation and different substrates have also been applied and studied. A factor in the selection was an adequate capillary climbing capacity. A layer of insulation was provided to some of the planter boxes to compensate for large shifts in temperature and to help protect against very low winter temperatures. A comparison with boxes without insulation revealed significant differences in the growth of plants according to their location.
