07:40 Widely grown in tropical countries for its fruit, the papaya makes an unusual ornamental foliage plant. The straight stem is usually unbranched and is topped by a cluster of long-stalked, deeply lobed leaves, which may reach up to 2ft/60cm wide on large plants.
The fragrant trumpet-shaped flowers, borne in summer, are cream or yellow and up to lin/2.5cm long. Male and female plants in close proximity are required if fruit production is the aim, although bisexual plants that have both male and female flowers, such as Carica papaya ‘Solo,’ have been bred. When the papaya is grown as a houseplant, pollination by hand may be necessary.
The 5-12-in/13-30-cm-long melonlike fruits are borne directly on the trunk, in the leaf axils. They are green and turn yellow or orange when ripe. The firm, fragrant flesh is yellow to pinkish orange.

- A temperature of at least 60°F/16°C is necessary to ripen fruit.
- Water well all year-round but do not overwater.
- If the soil becomes waterlogged, it will kill the plant within days.
