Fatsia japonica as a houseplant
Most people think of Fatsia japonica as a garden shrub, and in mild parts of the UK it thrives outdoors in sheltered positions. But grown indoors it is a remarkable houseplant - fast-growing, architectural, and tolerant of conditions that would defeat most tropical species. The leaves are the main attraction: deep glossy green, deeply lobed like an outstretched hand, and up to 40 cm across on a well-fed specimen. A mature indoor Fatsia can easily reach 1.5-2 metres in height, making it one of the most impactful statement plants available.
How to care for Fatsia japonica
Fatsia prefers bright, indirect light but will tolerate surprisingly low light levels - it is one of the few large-leaved plants that genuinely copes with a north-facing room. Water when the top half of the compost feels dry, allowing excess to drain freely. Fatsia does not like sitting in water and is susceptible to root rot if overwatered. Feed monthly from spring to autumn with a balanced liquid fertiliser. Keep the large leaves clean by wiping them occasionally with a damp cloth - this helps the plant absorb light efficiently and keeps spider mites at bay.
Temperature and positioning
One of Fatsia's great advantages as a houseplant is its tolerance of cool temperatures. It thrives between 10 and 20 degrees Celsius and can handle brief cold snaps better than most tropical houseplants. Avoid positioning near radiators or in hot, dry air, which causes leaf drop. Fatsia can spend summer months outdoors in a sheltered, shaded spot and brought back indoors before the first frosts. It benefits from good air circulation and does not like stagnant, stuffy rooms.
Varieties and related plants
Fatsia japonica is the most widely grown species, but there are several cultivars worth seeking out. 'Variegata' has leaves edged in creamy white and is particularly striking. 'Spider's Web' has a more intricate white speckled pattern across the whole leaf. x Fatshedera lizei is a hybrid between Fatsia and ivy that produces a climbing or sprawling plant with smaller lobed leaves - an excellent choice for covering a wall or trellis in a cool, shaded position.
