Camellia

Camellia japonica · also: Japanese camellia, Common camellia

Camellia is an evergreen shrub from Japan, Korea and China, with thick, glossy dark green leaves and large, rose-like flowers. It flowers from February to April, while the garden is still largely bare, in white, pink or red, single or double. It likes partial shade, acid soil and rainwater, just like a rhododendron. Planted in the ground in a sheltered spot it is hardy here; in a pot it needs a little more care.

Caution: Needs acid soil and rainwater, like rhododendron: on chalky soil or with tap water the leaves turn yellow.

Identify

Camellia: how do you recognise it?

Habit
Dense, upright, evergreen shrub of 2–5 m; slow-growing.
Leaf
Alternate, 5–10 cm, oval with a pointed tip, finely toothed, leathery and highly glossy.
Bark
Smooth, greyish-brown.
Flower
Large (6–12 cm) white, pink or red flowers, single or double; they drop off whole.
Fruit
Round, woody capsules.
Difference from rhododendron
Rhododendron has larger, untoothed leaves and trusses of funnel-shaped flowers in May.
Difference from cherry laurel
Cherry laurel has larger leaves and white flower spikes.

Looks like it, but isn’t

In your garden

Why grow it?

  • Large flowers from February to April, when little else is in bloom.
  • Evergreen, glossy leaves: a neat shrub all year round.
  • Grows in partial and full shade, even against a north- or west-facing wall.
  • Also lovely in a large pot on a cool patio.

Camellia: where does it grow best?

  • Partial to full shade, sheltered from cold east winds and early morning sun.
  • Humus-rich, acid, moisture-retentive soil that drains well; no lime.
  • Allow 2–3 m width in the long run.
  • In a pot: ericaceous compost and a large pot with a drainage hole.

Goes well with

  • Rhododendron: Needs the same acid soil and partial shade, and flowers in May, after the camellia.
  • Japanese skimmia: Evergreen, for the same shady, acid spot; red buds in winter.
  • Japanese pieris: Hanging white flower clusters in spring and red young leaves, in the same soil.
  • Hydrangea: Flowers in summer in the same partial shade: that way you have flowers from February into autumn.

Maintenance

Camellia: when and how to plant it?

  1. Plant in spring (April–May) or early autumn, so that it can still root before winter.
  2. Dig a generous planting hole and, on chalky or heavy soil, fill it with ericaceous compost or acid leaf mould.
  3. Don’t plant deeper than it was in the pot: the root collar stays just above the soil.
  4. After planting, water well with rainwater and mulch with bark or pine needles.

Care

Watering
Use rainwater, not tap water, which is often limy. Keep the soil moist in summer and late summer, or it will drop its buds later on.
Feeding
After flowering, a rhododendron fertiliser or acid leaf mould.
Soil
A layer of bark or leaf mould keeps the roots cool and moist.
In a pot
Water regularly, even in winter in dry weather, and in hard frost move the pot against a wall or into a cool, light room.

Tip: Plant a camellia against a west- or north-facing wall: there it escapes the morning sun and the flowers stay beautiful after a frosty night.

Camellia: when to prune it?

Pruning months: April–May.

When: After flowering, in April–May.

How:

  • Little needed: shorten overlong branches to just above a leaf or side branch.
  • Remove dead and weak branches; reduce an oversized shrub gradually over a few years.

Caution: Don’t prune after mid-June, as it is then forming next year’s buds.

Pruning: when and how · Pruning calendar and basic rules

Propagation

Cuttings
In July–August, take 10 cm semi-ripe cuttings with a few leaves and root them in acid cutting compost under plastic; this takes a few months.
Layering
Bend a low branch to the ground, nick it lightly and cover it with soil; after one or two years it will have roots.

Camellia: how does it get through the winter?

Hardy throughout Belgium: no protection needed.

  • Hardy in the ground in a normal winter; in hard frost flowers and buds can be damaged.
  • A camellia in a pot is more vulnerable: protect the pot from freezing or, in hard frost, move it into a cool, light room.

Diseases and pests

  • Bud drop: Buds fall before opening, usually because of drought in late summer or frost. Water regularly with rainwater.
  • Yellow leaves: Yellow leaves with green veins: soil too limy or tap water. Water with rainwater and give a fertiliser for acid soil.
  • Scale insects: Small brown scales under the leaves and a sticky black coating on top. Wipe them off or let ladybirds and parasitic wasps do their work.
  • Vine weevil: Half-moon notches in the leaf edges; the grubs eat the roots, especially in pots. Control them with nematodes in spring or late summer.

Through the year

  • February: Flowering starts; after a frosty night, shield from the morning sun.
  • March: Full flower.
  • April: Prune after flowering; feed.
  • May: Last pruning; planting.
  • June: No more pruning from mid-June: the buds are forming.
  • July: Take semi-ripe cuttings.
  • August: Water regularly with rainwater: drought makes the buds drop later.
  • November: Protect pots from frost.

Use

What can you use it for?

Garden and landscape
Evergreen shrub with large flowers while it is still winter; also in a pot on a cool patio.
Also used for
Related to the tea plant; in Japan, camellia oil is made from the seeds.

Caution: Needs acid soil and rainwater, like rhododendron.

You and this species

Did you know?

  • A relative of the tea plant (Camellia sinensis). Keep it out of the morning sun: frozen buds that thaw quickly turn brown.
  • In Japan, camellia oil is pressed from the seeds and used for hair and skin.
  • The genus is named after Georg Joseph Kamel, a Jesuit and botanist who worked in the Philippines in the 17th century.
  • Linnaeus named the camellia after Georg Joseph Kamel, a Moravian Jesuit and botanist who worked in the Philippines.
  • The camellia is the flower of Alexandre Dumas fils’s novel ‘La Dame aux camélias’, the story Verdi turned into his opera ‘La traviata’.
