Potted Forest Cedar

The dryad keeps the potted trees in stock, and current versions sell them whenever she is around. Older builds locked them behind hardmode, so if you are on a version that has not caught up, check her list again after the wall of flesh rather than assuming she never carried them.

The range follows the biome trees you would expect from her, but there are gaps. Nothing exists for corruption or crimson trees, and there is no boreal option, so a snow build or an evil biome build has to fill that slot with something else. The potted bamboo is a slight cheat too, drawn with a woody stalk rather than the flat green of the real plant. They sit flat on tables and counters and take one tile of surface, so a row along a shelf gives a nursery look without eating floor space.
