Streptocarpus saxorum - Trailing Cape Primrose - Welsh Grown

A trailing gem in the Gesneriad family, Streptocarpus saxorum produces dainty violet-blue flowers that rise above soft, fuzzy green leaves on slender stems. Unlike its upright cousins, this species forms graceful, arching growth and blooms repeatedly throughout the year. It’s ideal for hanging pots, shelf edges, or as a soft, flowering filler in mixed indoor arrangements.

Scientific Name
Streptocarpus saxorum (from Greek streptos, “twisted”, and karpos, “fruit”; saxorum means “of the rocks”, referencing its natural rocky habitat)

Originally described as Saintpaulia saxorum, this species was reclassified under Streptocarpus along with other African violets following taxonomic revisions in the Gesneriaceae family. Native to East Africa, it is valued for its unique trailing habit.

Common Name(s)
Trailing Cape Primrose, Trailing African Violet, Streptocarpus saxorum

Origin
Native to Tanzania and Kenya, where it grows on rocky slopes and in shaded crevices

Light
Prefers bright, indirect light. Will bloom best with several hours of filtered light each day. Avoid harsh sun, which can scorch the leaves.

Water
Water when the top 2–3cm of soil feels dry. Keep soil lightly moist but not soggy. Water less in winter and avoid getting the fuzzy leaves too wet.

Humidity
Prefers moderate humidity. Avoid misting directly – use a pebble tray or keep near other humidity-loving plants.

Soil
Use a light, well-draining mix – African violet compost or a blend of compost, perlite, and vermiculite works well. Repot every 1–2 years in spring to refresh the mix.

Food
Feed every 3–4 weeks in spring and summer with a diluted fertiliser designed for flowering houseplants or African violets.

Temp
Ideal temperature range is 18–24°C. Protect from cold draughts and temperatures below 12°C.

Pet-safe
Generally non-toxic – safe for pets and children.

Sprouts Top Tips
Pinch off faded blooms to encourage repeat flowering. If the plant becomes leggy, trim back to encourage bushier growth and re-root cuttings for a fuller pot.

Extras
Its naturally trailing habit makes Streptocarpus saxorum perfect for hanging baskets or for softening shelf edges in a bright spot.

Did You Know?
Though more delicate-looking than its upright cousins, Streptocarpus saxorum is surprisingly easy to care for and can bloom for most of the year with minimal fuss.
