  • C. japonica var. rusticana (Honda) T. L. Ming is known only in the wild. The flower has a shorter petiole, about 5 millimetre (0.196850393700787 in) long, with fine hairs (pubescent) at the base. The bracteoles and sepals are smooth (glabrous) on the outside.

Cultivation history

Camellia japonica has appeared in paintings and porcelain in China since the 11th century. Early paintings of the plant are usually of the single red flowering type. However, a single white flowering plant is shown in the scroll of the Four Magpies of the Song Dynasty

Camellias were first sold in 1807 in an American nursery as greenhouse plants, but were soon sold to be grown outdoors in the south.

Cultivars

Camellia japonica is valued for its flowers, which can be single, semi-double flowered or double flowered. There are more than 2,000 cultivar

s developed from C. japonica. The shade of the flowers can vary from red to pink to white; they sometimes have multi-coloured stripes or specks. Cultivars include 'Elegans' with large pink flowers which often have white streaks, 'Guilio Nuccio' with red to pinkish petals and yellow stamens, 'Mathotiana Alba' with pure white flowers, and the light crimson semi-double-flowered 'The Czar'

.

C. japonica 'Alba Plena' is nicknamed the “Bourbon Camellia”. Captain Connor of the East Indiaman, brought the flower to England in 1792. The flowers are pure white and about 3 to 4 inches across. It blooms earlier than most cultivated camellias, in the early winter or spring, and can flower for 4 to 5 months.

The zig-zag camellia or C. japonica 'Unryu' has different zig-zag branching patterns. “Unryu” means “dragon in the clouds” in Japanese; the Japanese believe it looks like a dragon climbing up to the sky. Another type of rare camellia is called the fishtail camellia or C. japonica 'Kingyo-tsubaki'. The tips of the leaves of this plant resemble a fish's tail.

Normally, camellias cannot be grown in colder climates. However, breeding of camellias has produced many cultivars which are tolerant of zone 5 and zone 6 winters. Camellias can now grow in parts of New England, Pacific Northwest, even Ontario, Canada. Camellias should be planted in the shade in organic, somewhat acidic, semi-moist but well drained soil. If the soil is not well drained, it can cause the roots to rot.

Diseases

Some fungal and algal diseases include: Spot Disease, which gives the upper side of leaves a silver color and round spots, and can cause loss of leaves; Black Mold; Leaf Spot; Leaf Gall; Flower Blight, which causes flowers to become brown and fall; Root Rot; and Canker caused by the fungus Glomerella cingulata

, which penetrates plants through wounds.
Some insects and pests of C. japonica are the Fuller Rose Beetle Pantomorus cervinus, the mealybugs Planococcus citri and Pseudococcus longispinus, the weevils Otiorhyncus salcatus and Otiorhyncus ovatus, and the tea scale Fiorinia theae.

Some physiological diseases include salt injury which results from high levels of salt in soil; chlorosis which is thought to be caused lack of certain elements in the soil; bud drop which causes loss or decay of buds, and can be caused by over-watering, high temperatures, or pot-bound roots. Other diseases are oedema and sunburn. Not much is known about viral diseases in C. japonica.

THE WHITE CAMELLIA JAPONICA

Thou beauteous child of purity and grace,
What element could yield so fair a birth?
Defilement bore me - my abiding place
Was mid the foul clods of polluted earth.
But light looked on me from a holier sphere,
To draw me heavenward - then I rose and shone;
And can I vainly to thine eye appear,
Thou dust-born gazer? make the type thine own.
From thy dark dwelling look thou forth, and see
The purer beams that brings a lovelier change for thee.
