Indoor size vs how big it gets in the wild

Torenia fournieri 'Catalina Midnight Blue' reaches its full size within one growing season — there is no "long-term" size, just how big it gets before you harvest or it dies back.

A pot, your light levels and a little pruning are what set the final size in a home, far more than the plant's theoretical potential.

It sizes up fast and once, racing from seedling to full size in a single season; after cropping it is finished, so size is a within-season question.
