spring onion, Chives • Hindi: Chhoti pyaz छोटी प्याज़ • Manipuri: Tilhou macha;

Leaves - raw, cooked or dried for later use. The leaves have a mild onion flavour and are an excellent addition to mixed salads, they can also be used as a flavouring in soups etc[2, 4, 5, 9, 27, 33]. The leaves are often available from late winter and can continue to produce leaves until early the following winter, especially if they are in a warm, sheltered position[K]. A good source of sulphur and iron[201]. A nutritional analysis is available[218]. The bulbs are rather small, and rarely exceed 10mm in diameter[200]. They can be harvested with the leaves still attached and be used as spring onions[K]. They have a pleasant mild onion flavour. The flowers can be used as a garnish in salads etc[183]. The flowers of this species are rather dry and less desirable than the flowers of many other species[K]. 
The whole plant has a beneficial effect on the digestive system and the blood circulation. It improves the appetite, is digestive, hypotensive and tonic[201]. It has similar properties to garlic (A. sativum), but in a much milder form, and it is rarely used medicinally[238]. 
The juice of the plant is used as an insect repellent, it also has fungicidal properties and is effective against scab, mildew etc[14, 18, 20, 201]. The growing plant is said to repel insects and moles[14, 20, 200]. 
(From PFAF
I returned a week ago from a two-week (27th May - 11th June) holiday in Ladakh. We covered some of eastern (Tangste, Pangong Tso) and southern (Hanle, Tso Kar & Moriri, Chumathang) Ladakh and drove back via the Leh-Srinagar highway, so a fair bit of western Ladakh too. Altitudes ranged from nearly 18,000 (skipped Khardungla as I had been there last time) to about 10,000 ft. The distant mountains from Leh (11,500 ft) were snow-capped and higher altitudes like Chang La were snow-bound. Farming at lower ranges and near rivers was in full swing and near Kargil the wheat and barley were about 3 ft tall. It would be fair to say that the weather was pre-spring to summer depending on the area. Some mountain sides and valleys in the more arid regions looked greenish or yellow and a closer inspection revealed grass just beginning to sprout. Flora in this cold desert is indeed very different, though one did encounter some cold temperate trees/shrubs, e.g. willow, poplar, lilac, etc.
Starting my posts with a few garden/potted plants seen in a hotel in Leh. 
Would be most grateful for ID help.
Schnittlauch (Allium schoenoprasum) from Ritterhude: One of my favorite substitute for garlic. The flowers are very pretty and a good source of food for the bees. The straw contains vitamin c and a and rich in calcium and other elements.
And more important, it survives the winter and makes me less work.

Looks like some Allium sp...
This was spotted in a garden of a Hotel premises.. Looks like cultivated one..

Pl. check comparative images of different species in efi at Allium if you find any match.

I think it matches with images at Allium schoenoprasum L. as per comparative images in efi at Allium

yes it does look like Allium schoenoprasum L. to me too, from the fotos. It is indeed cultivated in gardens the flowers and the "leaves-tubes" are used in the kitchen instead of garlic, as many people find garlic too strong smelling.
