Mirabilis: Greenhouse Plants

FF – frost free only / C – cool, minimum of 7°C (45°F) / W – warm, minimum of 13°C (55°F)

Family: Nyctaginaceae

Mirabilis jalapa is the Marvel of Peru and is a pretty little plant that can be grown outside in summer but is much better under glass away from the ravages of rain and wind. Plants can arrive as long tuberous roots which are potted in spring and watered carefully into growth, or as seed sown thinly and evenly in spring at 18°C (65°F) when they will germinate in two to three weeks. Plants are only 60 cm (2 ft) in height and produce trumpet-shaped flowers throughout the summer that can be white, yellow or bright pink. These flowers are closed in the morning and open during the afternoon so that their name is Four o’ Clock. They will die down in the autumn and should be taken from their pots and stored in a dry frost free place in a box of peat or sand much like a Dahlia tuber.
