Fun Facts
- 🌱 Japanese Fatsia is sometimes crossed with English Ivy (Hedera helix) to create the hybrid Fatshedera lizei, which combines traits of both parents and is more compact than pure Fatsia japonica.
- 🌱 The large palmate leaves can measure up to 12 inches across and contain up to 11 deeply cut lobes, making them among the most architecturally striking foliage in the shrub world.
- 🌱 In Japan, where it is native to the Ryukyu Islands, Japanese Fatsia is known as 'yatsude' (八手), meaning 'eight-handed,' referring to the leaf's multiple lobes.
