Edible Uses

Edible Uses: Oil;  Oil;  Tea.

An edible oil is obtained from the seed[11, 61, 105]. It is called 'tsubaki oil'[183]. Dried flowers - cooked[105]. Used as a vegetable or mixed with gelatinous-rice to make a Japanese food called 'mochi'[183]. The leaves are a tea substitute[142, 177, 178, 183].

Medicinal Uses



Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.

Astringent;  Cancer;  Haemostatic;  Salve;  Tonic.

The flowers are astringent, antihaemorrhagic, haemostatic, salve and tonic[178, 218]. When mixed with sesame oil they are used in the treatment of burns and scalds[218]. The plant has shown anticancer activity[218].

Other Uses

Dye;  Oil;  Oil.

A non-drying oil is obtained from the seed - used as a hair-dressing[46, 61]. The oil consists mainly of olein it is not subject to polymerize or oxidize, nor does it form solids at low temperatures[174]. A green dye is obtained from the pink or red petals[168].

Cultivation details

Landscape Uses:Border, Container, Espalier, Standard, Specimen. Prefers a woodland soil but thrives in a warm open well-drained loam if leafmould is added[1, 11, 200]. A calcifuge plant, preferring a pH around 5[11, 200]. Prefers the partial shade of a light woodland[200], it also grows well on a north-west aspect[11] and on sunless walls[202]. This is a very cold hardy plant, but it cannot tolerate cold winds[11]. Plants should be given a position shaded from the morning sun in order to protect the flowers from late frosts[219]. Prefers a wet summer and a cool but not very frosty dry winter[200]. Plants are not very self-compatible, self-fertilized flowers produce few seeds and these are of low viability[200]. A very ornamental plant[11]. A large amount of named forms have been developed, mainly for their ornamental value[11, 200]. Many of them tolerate full sun[182, 200]. Camellias are a valuable commercial crop in Asia, where they are cultivated for the oil obtained from their seed. Many of the cultivars grown in Britain do not set seed, unfortunately. The following cultivars have been seen with good crops of seeds:- 'Alba Simplex'; 'Coppelia'; 'Guillio Nuccio'; 'Jupiter'[K].The sub-species C. japonica macrocarpa. Masam. has larger fruits than the type, looking like small apples. The sub-species C. japonica rusticana (Honda.)Kitamura. is a hardier form from N. Japan where it grows at higher altitudes than the species and withstands long snowy winters[11, 219].Special Features:Attractive foliage, Not North American native, Blooms are very showy.

Propagation

Seed - can be sown as soon as it is ripe in a greenhouse[113]. Stored seed should be pre-soaked for 24 hours in warm water and the hard covering around the micropyle should be filed down to leave a thin covering[78, 113, 138]. It usually germinates in 1 - 3 months at 23°c[138]. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in light shade in the greenhouse for at least their first winter. Plant them out into their permanent positions when they are more than 15cm tall and give them some protection from winter cold for their first year or three outdoors[K]. Cuttings of almost ripe wood, 10 - 15cm with a heel, August/September in a shaded frame. High percentage but slow[78]. Cuttings of firm wood, 7 - 10cm with a heel, end of June in a frame[11, 78]. Keep in a cool greenhouse for the first year[11]. Leaf-bud cuttings, July/August in a frame.

Has anyone eaten the flowers? Can they be eaten raw? Can you cook them fresh? Here in the Oakland, CA, they are everywhere. It seems nearly every house has one growing! Does anyone recommend harvesting strategies for the tea?

my camellia flowers and buds have just dissapeared there one day gone the nex do you know anything that eats them ? regards s. taylor

david   Mon Aug 17 2009

I'm also interested in eating the flowers, (the fact that the plant takes full shade makes it interesting) but am nervous I cant find anything else on the net or in books about their edibility, also one of the only two sources listed here is at times "dubious". I've nibbled a few fresh, seem very inoffensive, pleasant bland, swallowed a tiny amount. That there is a somewhat more documented tradition of their use medicinally suggests they are safe, I found one Asian commercial supplier of petals for medicinal use which is encouraging. There is "Studies on the Constituents of the Flower of Camellia japonica (2)", from googling the identified chemicals all seem to be beneficial, anti-cancer and anti-depressant for instance, or occuring in commonly eaten foods, but I'm no chemist. It's possible they are dried simply for convenience not safety.

One of my horticulture instructors recommends Camellia oil for lubricating pruners. It is available for sale at a Japanese tool store in California (hidatool.com) The most common cultivar I've seen does not produce seeds. It has a mutation that turns the reproductive parts into additional petals. Pretty, but less useful.
