Punica: Greenhouse Plants
C – cool, minimum of 7°C (45°F) / W – warm, minimum of 13°C (55°F)
Punica granatum is the Pomegranate which is naturally distributed from SE Europe to the Himalayas. It can be hardy outside although severe winters may cut it right back or even kill it. Pomegranates rarely produce ripe fruit but are grown for their attractive bright red flowers produced in summer. It is P. g. ‘Nana’, the dwarf form, which makes a very useful little pot shrub for even the smallest greenhouse, flowering profusely when very small. Should plants become straggly they can be pruned back by two-thirds after flowering. Seed will germinate better if soaked for 24 hours prior to sowing and then sown at the surface at a temperature of 21-24°C (70-75°F). Always sow on to well-moistened and well-drainedand press the seed into the compost without actually covering it. Germination will take at least a month and the seed should not dry out. Small heeled will succeed well in spring.
