Fast shipping but upon planting, one of the bulbs is completely rotten, so it's beyond saving, what a shame.

Description
Allium triquetrum is a small ornamental garlic, which bears white bell-shaped flowers with green veins. Its stem has the characteristic of being triangular, hence its name of three-cornered garlic or three-cornered stem garlic.
It is a creeping bulbous plant, 20 to 50cm (8 to 20in) tall, with a glabrous, triangular, thick stem. It has deciduous, linear, medium green, flat leaves, 5 to 10mm wide. From March to May, inflorescences grow at the ends of the stems in loose umbels, with 3 to 5 white bell-shaped flowers with green hearts and central veins on the petals. When cut, it gives off a strong garlic smell.
Native to Mediterranean regions, Allium triquetrum tolerates all rich, moist but well-drained soils in warm situations. Mulch in winter to protect it from the cold. Be aware that it quickly becomes invasive when it is happy. Cultivation in pots is possible in regions with severe cold.
Allium triquetrum is used to dress banks or border pathways.
Attention: this species can become invasive in mild and oceanic climates, causing significant ecological disorders. It can be replaced by many other varieties of ornamental garlic.

Planting and care
Plant Allium triquetrum in autumn in rich, moist but well-drained soil in a warm location, spaced 15cm (6in) apart. Add sand to the planting hole to improve drainage and avoid overly acidic soils. It can withstand harsh winters if water is not allowed to stagnate and by protecting it with a good mulch. Alternatively, you can grow it in a pot in good, loose and well-drained compost.

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).
The flowering period indicated on our website applies to countries and regions located in USDA zone 8 (France, the United Kingdom, Ireland, the Netherlands, etc.)
It will vary according to where you live:- In zones 9 to 10 (Italy, Spain, Greece, etc.), flowering will occur about 2 to 4 weeks earlier.
- In zones 6 to 7 (Germany, Poland, Slovenia, and lower mountainous regions), flowering will be delayed by 2 to 3 weeks.
- In zone 5 (Central Europe, Scandinavia), blooming will be delayed by 3 to 5 weeks.
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 planting period indicated on our website applies to countries and regions located in USDA zone 8 (France, United Kingdom, Ireland, Netherlands).
It will vary according to where you live:
- In Mediterranean zones (Marseille, Madrid, Milan, etc.), autumn and winter are the best planting periods.
- In continental zones (Strasbourg, Munich, Vienna, etc.), delay planting by 2 to 3 weeks in spring and bring it forward by 2 to 4 weeks in autumn.
- In mountainous regions (the Alps, Pyrenees, Carpathians, etc.), it is best to plant in late spring (May-June) or late summer (August-September).
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.
