Plant Type:
Woody Perennial
Tetrapanax papyrifer ‘Rex’, also known as the Chinese rice-paper plant ‘Rex’, is a striking, fast-growing shrub or small tree prized for its enormous, deeply lobed, palmate green leaves, often reaching up to 1 meter across. New growth displays a soft, pale brown fuzz. In autumn, it produces large sprays of creamy-white, globe-shaped flowers, followed by black fruit. This architectural plant creates a tropical feel and can reach 4-8 meters in height and spread. It’s best grown in well-drained soil in full sun to part shade, needing protection from cold winds. In colder areas, it may die back in winter but typically reshoots from the base.
Cold Hardiness:
Half Hardy – Hardy when mature
In the UK, Tetrapanax papyrifer ‘Rex’ is considered half-hardy (H3-H4), meaning it’s hardy in most of the UK but may need winter protection, especially in colder regions or during severe winters. It can tolerate temperatures down to -5°C to -10°C. In colder areas, the top growth may die back, but it usually reshoots from the base in spring. Providing a deep mulch around the base can help protect the roots from freezing. Younger plants and those in pots are more vulnerable and benefit from extra protection like wrapping in horticultural fleece. In milder areas, it might remain semi-evergreen.
Eventual Height:
4-8m
In UK gardens, Tetrapanax papyrifer ‘Rex’ typically reaches an eventual height of 4 to 8 metres (13 to 26 feet). It’s a fast-growing plant, potentially reaching this size within 2 to 5 years in favourable conditions. However, in colder areas where it experiences dieback, it may remain smaller.
Light requirements:
Full sun /Partial shade
Tetrapanax papyrifer ‘Rex’ thrives in full sun to partial shade in the UK. While it appreciates plenty of sunlight for optimal growth and the largest leaves, it can tolerate some shade, especially in warmer locations to prevent leaf scorch. A sheltered spot is crucial to protect its large leaves from wind damage, regardless of the light level.
Water Requirements:
Frequent
Tetrapanax papyrifer ‘Rex’ needs consistent moisture, especially during the warmer months and establishment. Water deeply when the top inch of soil feels dry. While it can tolerate some drought once established, regular watering promotes the largest, healthiest leaves. Ensure good drainage to prevent waterlogging, which it dislikes. A mulch helps retain soil moisture.
Caring for this plant:
Spring: Protect emerging shoots from late frosts. Feed with a balanced fertiliser as growth starts.Water regularly, especially during dry spells.
Summer: Ensure consistent moisture, particularly for potted plants. Protect from strong winds to prevent leaf damage. Consider light pruning to maintain shape if needed. Monitor for pests.
