Japanese Ivy

Hedera rhombea

The Story

Plant Bio

Hedera rhombea, Japanese ivy, is a clinging evergreen vine of temperate eastern Asia, climbing ten to thirty feet. Juvenile leaves are diamond-shaped with three lobes and a heart-shaped base while adult branch leaves are mostly plain oval, and small yellow-green flowers in autumn give round berries that blacken through winter into spring.

The two leaf shapes belong to the same plant: juvenile climbing growth is lobed and diamond-shaped, adult flowering wood is plain and oval, so a mature vine looks like two species at once. It is smaller and better mannered than the common and Persian ivies, which makes it the one that suits a container or a modest wall.

Uses & Benefits:

Ornamental UsesEvergreen cover with two distinct leaf shapes, and black berries that hold from winter into spring.
Practical UsesSmaller and better mannered than common or Persian ivy, so it suits a container or a modest wall.
Ecological BenefitsAutumn flowers draw pollinators and the winter berries feed birds when food is scarce.

Planting

How to Grow

  1. Plant in shade or dappled light in drained soil.
  2. Give it a wall, trellis or post to cling to.
  3. Water while establishing, then leave it alone.
  4. Trim in spring to keep it within bounds.
  5. Grow it in a container to limit spread.
  6. Leave adult wood if you want the berries.

Pro Tip

Cut only juvenile lobed growth for cuttings — pieces taken from adult oval-leaved wood root into bushes that never climb.
