Indoors and in a pot, expect around 20-30 cm tall in flower and 25-30 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 grows mostly by adding leaves, offsets or a slightly wider rosette rather than gaining height — the footprint barely changes year to year.

Growth rate and years to mature

Streptocarpus 'Falling Stars' is a moderate grower. Realistically, expect three to six years to reach mature indoor size, gaining a steady amount each growing season. Its feeding profile backs this up: feed every 1-2 weeks during spring and summer with a high-potash or balanced liquid feed at half strength to fuel prolific blooming. reduce or stop feeding in autumn and winter while the plant rests.

It is already in good light; consistent warmth and a balanced feed in spring and summer are the only levers.
A small step up in pot size every couple of years gives the roots a little more room without triggering a size jump.
Feed lightly through the growing season; this plant simply will not race however hard you push it.

Light is almost always the ceiling. The streptocarpus 'falling stars' light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When streptocarpus 'falling stars' outgrows the room (or the pot)
