Japanese photinia is an evergreen shrub grown for its glossy leaves and bronzy-red new growth. It is native to Japan, southern China, and northern Indochina, and in the US it is mainly a landscape plant in the South. It is one parent of the hybrid Photinia × fraseri, which includes the popular cultivar 'Red Robin'.

Appearance

Growth form
A large shrub or small tree, usually 10–12 ft (3–3.5 m) tall and 6–10 ft (2–3 m) wide in gardens; unpruned plants can reach about 20 ft (6 m), and Japanese sources give up to about 33 ft (10 m) for wild trees.
Leaves
Leathery, glossy, 2–3½ in. (5–9 cm) long, with fine teeth. New leaves are bronzy red and turn dark green.
Flowers
Flat clusters 2–5 in. (5–12 cm) wide of small white flowers, sometimes tinged pink. They open around June, later than other photinias. The scent reminds some people of hawthorn; others find it unpleasant.
Fruit
Small round fruits about ⅛–¼ in. (3–6 mm) wide turn red in fall and later black.

Look-alikes

Photinia × fraseri ('Red Robin' and other cultivars)Photinia × fraseri

Very hard to tell apart in photos. 'Red Robin' has deeper, crimson-red new leaves, and the hybrid tends to bloom in mid-spring, before Japanese photinia, which blooms around June.

Why they get mixed upIt is a hybrid with Japanese photinia as one parent, with the same red new growth.

Chinese photiniaPhotinia serratifolia

Chinese photinia grows into a larger shrub or small tree with bigger, longer leaves on longer, hairy young leaf stalks (up to about 1¾ in., or 4.5 cm). Japanese photinia's leaf stalks are only ¼–½ in. (6–12 mm) and hairless.

Why they get mixed upBoth are evergreen photinias with toothed leaves and white flower clusters, and both are planted in the South.

Where it lives

Typical habitats
  • Gardens
  • Hedges
  • Landscape plantings
Range
Native to southern and central Japan, southern China, and northern Indochina. In the US it is planted as an ornamental, and it has been introduced in Louisiana.
Preferred conditions
Hardy in USDA zones 7a–10b; it is the least cold-tolerant of the photinias. It likes moist, well-drained soil in full sun to part shade, tolerates alkaline soil, and handles drought once established.

Growing it

Care
Used for hedges, screens, and as a small flowering tree. Leaf spot is the main problem in hot, humid summers in zones 8 and 9, so water at the soil line and give it good air flow. 'Rubens' is a cultivar with bright bronzy-red young leaves.
