Dating the origin of the orchidaceae
The white flowers, which infrequently have a pink tinge, appear in loose clusters above whorls of three-lobed leaves of a pale, dusky khaki-green colour.The picture shows it growing in the corner of a shady trough, but I also grow it amongst other woodland and ericaceous plants where it has obligingly seeded itself about forming an attractive swathe of about 12 centimeters high with a spread of about 60 centimeters.It has played a pivotal role in cooking worldwide, as the various parts of the plants, either raw or cooked in many ways, produce a large variety of flavors and textures.The genus contains hundreds of distinct species; many have been harvested through human history, but only about a dozen are still economically important today as crops or garden vegetables. Allium triquetrum is native to south-western Europe, north-western Africa, Madeira and the Canary Islands, where it grows in meadows, woodland clearings, on river banks and roadside verges from sea level to an altitude of 850 metres (2,790 ft).The tepals are 10-18 millimetres (0.4-0.7 in) long and white, but with a "strong green line".
This is a most delicate and lovely little plant from the woodlands of Missouri, typically seen in the wild on wooded slopes and ridges.
It is readily available from a number of nurseries and a mature plant in full flower will stop people in their tracks as they pause to gaze at it.
I think it should be seen more widely in alpine gardens.
It is an outstanding dwarf shrubby plant that originated around 1910 in the then famous garden belonging to the late Miss Ellen Willmott at Great Warley in Essex.
It grows to a height of about 18 centimetres and flowers from May to August.
