An evergreen greenhouse perennial, or house plant, that is grown for its attractive foliage.
They are also suited to growing in bottle gardens.
They generally grow to around 600mm (24") high with a 500mm (18") spread.
Week 22; Re-pot the plants up annually into well crocked 150mm (6") pots of potting compost.
Week 23; Give fortnightly liquid feeds from now until September.
Week 26; Divide crowns so that each piece retains a few leaves and sturdy roots, and grow on at around 18°C (65°F)
Keep plants in light shade at all times.
Avoid direct sunlight as this might 'bleach' the leaves.
Water regularly during the growing season, and keep the atmosphere around the plant quite moist / humid.
Humidity can be controlled by sitting the pot in a larger pot, and filling the gap with moist sphagnum moss.
Alternatively sit the pot on a saucer of pebbles and fill the saucer with water.
Keep the plants just moist in winter.
A minimum winter temperature of 16°C (60°F) is required.
