In that case Matteo you need to get yourself to Wavre market on a Wednesday morning if possible as there are lots of Flemish nurserymen who sell plants there in the square in front of the church that plays the carillon. Some are also there on Saturday. Fairly standard plants but good prices.
I have friends who swear by this nursery near Céroux-Mousty - http://www.letry.be/ for good shrubs and conifers.
There are also plant fairs in autumn and spring where you can get non bog standard plants from specialist nurserymen and women who are happy to chat about what their plants need to grow well and how big they'll get and how hardy they are:-
12 & 13/9 Hex
26 & 27/9 Celles - La Feuillerie
4/10 Kalmthout Arboretum
2 to 4/10 Aywiers, Lasne
9 to 11/10 Beervelde, near Ghent
Google them for addresses and times.
I get my metal trellis grid from Big Mat on the Ch de Tirlemont at Gembloux. It comes in 5m x 2m lengths and they will deliver.
