Cultivation:
Prefers a moist sandy woodland soil in a cool position with partial shade. This is a very ornamental but difficult plant to grow. It requires a mycorrhizal relationship in the soil and therefore needs to be grown initially in soil collected from around an established plant. It is also very difficult from seed as well as being intolerant of root disturbance which makes division difficult. The flowers have a soft almond scent.

Propagation:
Seed – the only information we have on this species is that it is difficult from seed and germinates infrequently. We would suggest sowing the seed as soon as it is ripe if this is possible. Sow it into soil collected from around an established plant, only just covering the seed, and put the pot in a shady part of a cold frame. Pot up any young seedlings as soon as they are large enough to handle, once again using soil from around an established plant. Plant out into their permanent positions when the plants are large enough. You should not need to use soil from around an established plant to do this since the soil in the pot will contain the necessary micorrhiza. Division with great care in the spring[1, 111]. Pot up the divisions using some soil from around an established plant, grow on in a lightly shaded part of a greenhouse or frame and do not plant out until the plants are growing away vigorously

Edible Uses: Edible Parts: Fruit; Leaves…..Fruits & Leaves are said to be eaten raw

Medicinal Uses: The plant is antispasmodic, astringent, diuretic and tonic.

Botanical Name ; Artemisia annua
Family: Asteraceae
Genus: Artemisia
Species: A. annua
Kingdom: Plantae
Order: Asterales

Common Names :Sweet Wormwood,  Sweet Annie,  Sweet Sagewort or Annual Wormwood, Qing Hao

Habitat : Artemisia annua is native to temperate Asia, but naturalized throughout the world.
It occurs naturally as part of a steppe vegetation in the northern parts of Chahar and Suiyuan provinces in China, at 1000 to 1500 m above sea level.

Description:
Artemisia annua has fern-like leaves, bright yellow flowers, and a camphor-like scent. Its height averages about 2 m tall, and the plant has a single stem, alternating branches, and alternating leaves which range 2.5–5 cm in length. It is cross-pollinated by wind or insects. It is a diploid plant with chromosome number, 2n=18

Cultivation:
An easily grown plant, succeeding in a well-drained circumneutral or slightly alkaline loamy soil, preferring a sunny position. Plants are longer lived, more hardy and more aromatic when they are grown in a poor dry soil. A fast-growing annual plant, it is tall but neat in habit with a handsome fragrant foliage and is useful for filling gaps at the back of a border. It has become a weed of waste places in many areas of the world. The plant is extremely vigorous and essentially disease and pest free. Qing Hao is a determinate short-day plant. Non-juvenile plants are very responsive to photoperiodic stimulus and flower about two weeks after induction. The critical photoperiod seems to be about 13.5 hours, but there are likely to be photoperiod x temperature interactions. In Lafayette Indiana, USA (40°21’N) plants flower in early September with mature seeds produced in October. The plant is not adapted to the tropics because flowering will be induced when the plants are very small. Most collections of artemisia derive from natural stands with highly variable artemisinin content, some as low of 0.01%. Selections from Chinese origin vary from 0.05 to 0.21%. Swiss researcher N. Delabays reports a clonal selection derived from Chinese material which produces 1.1% artemisin but is very late flowering; proprietary hybrids have been obtained with somewhat lower content but flower earlier. Members of this genus are rarely if ever troubled by browsing deer.

Propagation:
Seed – sow spring in a cold frame and plant out in late spring or early summer. Alternatively, the seed can be sown late spring in situ

Edible Uses: An essential oil in the leaves is used as a flavouring in spirits such as vermouth.

Medicinal Uses:
Qing Ho, better known in the West as sweet wormwood, is a traditional Chinese herbal medicine. An aromatic anti-bacterial plant, recent research has shown that it destroys malarial parasites, lowers fevers and checks bleeding.  Also used for heat stroke. Used as an infusion.  Externally the leaves are poulticed for nose bleeds, bleeding rashes, and sores.  Research in Thailand and the US shows that A. annua, in the preparation Artesunate, is an effective antimalarial against drug-resistant strains of the disease. Clinical trials have shown it to be 90% effective and more successful than standard drugs. In a trial of 2000 patients, all were cured of the disease. The seeds are used in the treatment of flatulence, indigestion and night sweats.
TCM:
Indications: summer colds, sweatless fevers, malaria, nocturnal sweats, heat excess.  An excellent refrigerant remedy in ailments of “empty-hot” excess.

Sweet Wormwood was used by Chinese herbalists in ancient times to treat fever, but had fallen out of common use, but was rediscovered in 1970’s when the Chinese Handbook of Prescriptions for Emergency Treatments (340 AD) was found. This pharmacopeia contained recipes for a tea from dried leaves, prescribed for fevers (not specifically malaria).

Other Uses:
Essential; Herbicide; Miscellany.

The plant is used in China as a medium for growing Aspergillus which is used in brewing wine. The substances mentioned above in the medicinal uses, used in the treatment of malaria, also show marked herbicidal activity. The plant yields 0.3% essential oi. This has an agreeable, refreshing and slightly balsamic odour and has been used in perfumery.
Known Hazards  : Skin contact with the plant can cause dermatitis or other allergic reactions in some people. The pollen is extremely allergenic.
