About this seed
Petunia 'Rose of Heaven' is a compact petunia, 30–35 cm tall, with large single bright-pink flowers 5–7 cm across and a dark centre. Petunia seed needs light to germinate, so sow it on the surface. The packet holds 100 seeds.
Sow on the surface, indoors
Press the seed onto moist mix without covering it. Typical for the species, seedlings appear in about 7–10 days when sown indoors at an air temperature of about 24 °C (approximate).
Plant out in sun
- Choose well-drained, fertile soil at pH 6.0–7.0.
- Give at least 6 hours of direct sun a day.
- Water regularly; keep the soil moist but not waterlogged. Mulch helps hold moisture.
Keep it flowering
Plants flower from mid-summer into autumn. Remove spent flowers to keep new buds coming and the plant tidy. A balanced fertiliser in spring supports growth. The compact, bushy habit and sturdy stems suit beds, borders and containers.
