Growing information

🌱 Sowing

• In climates like Ireland, sow from April to June for flowering from summer into early autumn.​

☀️ Light

• Prefers full sun, though light partial shade is tolerated and can still give a good display.​

💧 Watering

• Water regularly after sowing and during establishment, then as needed in dry spells.

• Avoid waterlogging; these are typical border annuals that like reasonably drained soil.​

🌡️ Germination

• Germination is usually straightforward in mild spring conditions; seeds sprout over 1–3 weeks depending on species and temperature.​

📏 Spacing & size

• Broadcast sow thinly and thin young plants where crowded, aiming for roughly 20–30 cm between clumps so they can fill out without smothering one another.​

• Mature plants reach about 80–90 cm, with a natural, slightly informal habit ideal for cottage‑style borders.​
