How to Grow Salpiglossis Sinuata (Painted Tongue) Seeds
Painted Tongue, also known as Salpiglossis, is a striking annual prized for its vibrant, velvety flowers in a wide range of colours and intricate patterns. It is best sown indoors in late winter to early spring, about 8–10 weeks before the last expected frost, giving seedlings time to establish before transplanting outdoors.
Sowing Painted Tongue Seeds
Use well-draining seed compost in trays or small pots. Sow seeds on the surface without covering, as they need light to germinate. Keep the compost consistently moist but not waterlogged by misting gently. Germination usually takes 10–14 days at around 15–20°C.
Transplanting & Spacing
Once seedlings have developed their first true leaves, thin them so the strongest plants remain. Transplant outdoors after all danger of frost has passed, spacing plants around 25–30 cm apart in sunny, sheltered positions.
Growing Conditions
Painted Tongue prefers fertile, well-draining soil and grows best in full sun, although it can tolerate light partial shade in hotter climates. Water regularly, especially during dry spells, but avoid overwatering. Mulching can help retain soil moisture and suppress weeds.
Flowering & Care
Flowering generally occurs from summer through autumn, producing trumpet-shaped blooms in rich, vibrant hues. Deadhead regularly to encourage continuous blooming and prevent plants from setting seed too early. Occasional feeding with a balanced liquid fertiliser can support a longer flowering period.
Additional Tips
- Painted Tongue prefers well-drained soil; avoid heavy clay or waterlogged areas.
- Taller varieties may need light staking to prevent flopping.
- Young seedlings are frost-sensitive and should be protected during cold snaps.
- Succession sowing every few weeks can help extend the flowering season.
Painted Tongue is an excellent choice for borders, containers, and cottage gardens, and its colourful flowers also attract bees and other pollinators.
