Problem with the delivery... The pots arrived in pieces. It looked like they were delivering a bag of concrete. Good overall follow-up and delivery on time.

Description
Mountain Tea, in Latin Sideritis syriaca, is a perennial aromatic and medicinal plant. It forms small, very low tufts and has small, woolly, silver-grey, aromatic, evergreen leaves. In late spring, the cushion comes alive with small, light yellow flowers grouped in spikes. Leaves, stems, and especially dried flowers have been used by shepherds in the Cretan mountains who prepare an invigorating and fragrant herbal tea, sweetened with honey and lemon. This Greek tea is both a preferred plant for dry rock gardens and arid areas of the garden and one of the gems of the simple garden.
Endemic to Crete, Sideritis syriaca spontaneously grows on rocks and limestone scree, between 1200 (1320) and 2000m (2187 yards) above sea level. It is a botanical species belonging to the Lamiaceae family, just like thyme, savoury, and oregano. This perennial plant develops into a tuft of 10-15 cm (4-6in) in height and 30-40 cm (12-16in) in spread. Its stump slightly suckers, so it can spread to form groundcover. The narrow, elongated leaves are covered with a woolly down that gives them a lovely silver-grey colour. When crushed, they give off a fresh, peppery smell. The flowering occurs in May-June. It takes the form of flower spikes 40 cm (16in) high adorned with very small bilabiate flowers in light yellow with acid green bracts, which are very bright. This flowering, like that of all plants in the Lamiaceae family, attracts numerous pollinators. Extremely resistant to summer drought, this Greek mountain tea can also withstand short freezes of around -15°C (5°F).
Sideritis syriaca is primarily a beautiful plant for sunny and dry, poor, rocky soil, valuable for gardens near the sea or Mediterranean regions without irrigation. It finds its place in rock gardens, gravel beds, with aromatic plants, or even as an edging along a pathway. It can be associated with thyme, shrubby salvias, marjoram (Origanum majorana), compact lavenders, savory, teucrium, low cistus, and other santolines to evoke the scrubland in a dry area of the garden. One of the charms of this type of arrangement lies in the scents emitted by all these plants after a hot day: they blend into a complex fragrance to be enjoyed with closed eyes: intense, captivating, it constitutes the quintessence of the Mediterranean countryside.
Properties and uses:
Sideritis syriaca has been known since antiquity as a medicinal plant and is still used as a beverage or remedy in Greece, Bulgaria, and Albania. Delicious invigorating herbal tea is prepared with the flowers and leaves. Harvest the flower spikes and leaves during the flowering period and hang them to dry in a dark and well-ventilated place. Infuse, like tea, and serve with a little lemon juice and honey. This mountain tea is attributed with anti-inflammatory, antibacterial, and immune system stimulating properties.

Planting and care
The Greek Mountain Tea is a plant perfectly adapted to the Mediterranean climate. It requires full sun and a very well-drained soil, preferably poor, even very chalky and rocky. It is undemanding, but it dislikes strong frosts that harm its hardiness. In a porous soil, it will withstand short frosts of around -15°C (5°F). Plant it preferably in early autumn in a favourable climate, but after the last frosts. Like many plants of scrubland, it cannot tolerate waterlogged soils in winter, nor too frequent watering in summer: the combination of heat and moisture in the soil can be fatal to it. Water this plant only as much as necessary for its establishment, prioritising generous but spaced waterings (every 8 to 15 days). Do not provide it with potting cpmpost or fertiliser, simply lighten the soil in your garden with a large amount of gravel and plant it in a raised bed or in a dry rock garden.
A poor and dry soil allows this plant to live longer.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
