French Tamarisk


Taken from Wikipedia...
Tamarix gallica, or French Tamarisk is a deciduous, herbaceous, twiggy shrub or small tree about 5 m high, indigenous toSaudi Arabia and the Sinai Peninsula, and very common around the Mediterranean region. It was first described for botanical classification by the taxonomist Carolus Linnaeus in 1753, but had already been in cultivation since 1596
It has fragile, woody branchlets that drop off in autumn along with the small, scale-like leaves that cover them. The leaf-shape is an adaption over time to exceedingly dry conditions.
The pink flowers are tiny, hermaphroditic, and are borne on narrow, feather-like spikes. They frequently bloom earlier than the leaves, first in May, and sometimes a second time in August.

Physical Characteristics

icon of man icon of shrubA decidious Shrub growing to 4m by 6m at a medium rate.
It is hardy to zone 5. It is in flower from June to August. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Bees. It is noted for attracting wildlife.
The plant prefers light (sandy), medium (loamy) and heavy (clay) soils, requires well-drained soil and can grow in heavy clay soil. The plant prefers acid, neutral and basic (alkaline) soils and can grow in very alkaline and saline soils. It cannot grow in the shade. It requires dry or moist soil. The plant can tolerate maritime exposure.

Habitats

Woodland Garden; Sunny Edge; Dappled Shade; Hedge;

Edible Uses

Edible Parts: Manna.
A manna is produced by the plants in response to insect damage to the stems[2, 105]. It is sweet and mucilaginous[105]. There is some confusion over whether the manna is produced by the plant, or whether it is an exudation from the insects[4]. The insects in question live in the deserts around Israel, it is not known if the manna can be produced in Britain[K].

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.
The branchlets and the leaves are astringent and diuretic[7]. An external compress is applied to wounds to stop the bleeding[7]. The manna produced on the plant is detergent, expectorant and laxative[240]. Galls produced on the plant as a result of insect damage are astringent[240]. They are used in the treatment of diarrhoea and dysentery[240].

Other Uses

Very tolerant of maritime exposure, it makes a good shelter hedge in coastal gardens[7, 11, 49, 75]. It dislikes being trimmed[75]. The plant has a rather open habit, however, and so is not tremendously effective at reducing wind speeds[K]. The extensive root system of this plant makes it suitable for use in erosion control in sandy soils[149]. The plant contains a high level of tannin[7]. Galls produced on the plant as a result of insect damage contain up to 40% tannin[240]. The tannin can be used as a dyestuff for fabrics[7]. (No details are given about the colour, though it is likely to be some shade of brown.) Wood - fairly hard, not strong, close grained, takes a high polish, it is often twisted or knotty[61, 149, 227]. Used for general construction, poles, turnery[61, 149]. It makes a good fuel, burning well even when green due to the wax content of the wood[74].

Cultivation details

An easily grown plant, succeeding in most soils and tolerant of saline conditions[11]. Grows well in heavy clay soils as well as in sands and even shingle[182]. Usually found near the coast, it succeeds inland if given a fairly good deep loam and a sunny position[11, 200]. Tolerant of maritime winds and dry soils when grown near the coast[11], plants require a moister soil and shelter from cold drying winds when they are grown inland in non-saline soils because they use the soil salts that are found in saline soils to help them reduce transpiration[200]. This species flowers on the current year's growth[227]. Any pruning is best carried out in spring, hedges are also best trimmed at this time[188]. Plants are tolerant of severe pruning, sprouting freely from old wood[K]. The very closely related T. anglica is often included in this species. A good bee plant[74]. This species is notably resistant to honey fungus[88, 200].

Propagation

Seed - sow spring in a cold frame and only just cover the seed. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Cuttings of half-ripe wood, July/August in a frame. Very easy[200]. Cuttings of mature wood of the current seasons growth, 15 - 25cm long, planted outdoors in late autumn in a nursery bed or straight into their permanent position. High percentage[11, 200].
