Each summer my verandah grows its own walls on the west and north-west.
Although the ornamental grape and the wisteria have been pruned right back to leafless woody stems, come spring they begin to reach out for each other and interwine.
By Christmas they have made dense, multi-layered walls of greenery that keep my verandah shaded, cool and dry.
Just like man-made walls, they incorporate a window and a door, although if I am away for more than few days I return to catch them trying to fill in the gaps, tendrils searching across thin air for the other side.
Apart from their practical function, unlike shadecloth for example, they are beautiful and varied in colour and form.
And they’re free!
