Indoor size vs how big it gets in the wild

Indoors and in a pot, expect 20-30 cm tall and 20-25 cm wide. 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.
