Vinetuners

Vinetuners can manipulate non-animal life (basically, plants and fungi).
As a vinetuner grows, they can grow more organisms at a faster rate. Just beginning, they can grow a seed or flower. A standard vinetuner can restore a sick plant to health, and increase the growth rate of several plants (not in a "several months grown in one hour" way, but in a "several months grown in just a couple months" way). These vinetuners generally find work on farms, or in medical fields, growing necessary plants for healing and medicine. Several powerful vinetuners together can grow large plants instantly; hundreds (if not thousands) working together could raise a forest in as many hours as it took them to walk the area.

Specialties

Most vinetuners find their work with living plants comes the most easily to them, but some branch into the world of working with plant materials.
Plantweaver - work with cloth made from plant fibers - cotton, linen, etc. They can't perform their craft without the tools used by non-Grace weavers, but are able to smooth out imperfections in their materials and knit more closely than a non-Grace with a similar level of experience and skill.
Work with archery - no specific name, but vinetuners often use their power to reduce the physical strain of drawing a bow, as bending the wood of the bow is easier for them than pulling a bowstring. Should a vinetuner be as physically strong as a non-Grace archer, they would experience little benefit from this aspect of their power. Many vinetuners pursuing archery often use their power when learning the weapon as a crutch, and simply never bother to develop the muscle required to go without it.
