× Fatshedera lizei was created by crossing Fatsia japonica 'Moserii' (Moser's Japanese fatsia, the seed parent) and Hedera helix (common ivy, the pollen parent) at the Lizé Frères tree nursery at Nantes in France in 1912. Its generic name is derived from the names of the two parent genera.

Description

The plant combines the shrubby shape of Fatsia with the five-lobed leaves of Hedera. As a shrub, × F. lizei can grow up to 1.2 m tall, above which the weight of the fairly weak branches makes them tend to bend over. It can however also be tied to a support and grow into a vine up to 3–4 m tall; unlike Hedera, it does not readily climb without assistance. The leaf blades are 7–25 cm long and broad, with a 5–20 cm petiole. The flowers are 4–6 mm diameter, yellowish-white, produced in late autumn or early winter in dense umbels; they are sterile and do not produce any fruit. However, specimens have been reported, which did produce not only flowers but also clusters of berries, one of which put forth shoots in the pot.

Cultivation

It is grown both as a garden plant outdoors, and as a houseplant indoors, where its tolerance of shady conditions is valued. Inside it grows well in bright indirect light. Outdoors, it can tolerate winter temperatures down to −15 °C, but can also be grown successfully indoors with temperatures never falling below 20 °C. Several cultivars have been selected, with dark green to variously white- or yellow-variegated leaves.

× Fatshedera lizei,[2] together with the cultivars 'Annemieke'[3] and 'Variegata'[4] have gained the Royal Horticultural Society's Award of Garden Merit.[5]
