This is a spell which rapidly grows a set of trees, cast on an existing seeds or saplings, allowing their branches to intertwine to the caster’s design. The intent is to cast upon many plants at once to imitate rooms, walkways, barriers, etc. Spells which do this are frequently high level as the smallest base effect is level 15, and from there the magnitudes stack quickly. A subtle caster may mark trees amongst a wider set with a sigil or paint so they can be easily identified as a Target: Group.
Although it would only be a note in the setting, the same spell could be used to guide the rapid growth of plants such as grape vines or fruit trees on farms in a manner which makes them easier to manage.

The targeted seeds and saplings mature over the day duration to their adult size in an alignment and layout to suit the casters desire. Branches may be intertwined, leaves given favorable angles, and limited only to the broad fundamentals of their plant type.
