Allium oschaninii, the French gray shallot, griselle or true shallot, is a perennial plant of the onion genus Allium. [2] It forms underground bulbs much like the (French red) shallots, covered by a layer of pale brown-grey skin (hence the common name).
The shallot is a cultivar group of the onion.Until 2010, the (French red) shallot was classified as a separate species, Allium ascalonicum.The taxon was synonymized with Allium cepa (the common onion) in 2010, as the difference was too small to justify a separate species.
Plants grow on rocky slopes and in fields at elevations of 1,500–2,500 m (4,900–8,200 ft). [ 5 ] [ 7 ] It is a typical 'drumstick allium', with a more-or-less spherical umbel on a tall stipe , and as such has often been confused with other similar species.
Allium flavum (yellow) and Allium carinatum (purple). Allium is a large genus of monocotyledonous flowering plants with around 1000 accepted species, [4] [5] making Allium the largest genus in the family Amaryllidaceae and amongst the largest plant genera in the world. [6]
Shallots are the most important subgroup within this group and comprise the only cultivars cultivated commercially. They form aggregate clusters of small, narrowly ovoid to pear-shaped bulbs. Potato onions differ from shallots in forming larger bulbs with fewer bulbs per cluster, and having a flattened (onion-like) shape. Intermediate forms ...
A. cepa var. aggregatum (formerly A. ascalonicum) – commonly called shallots or sometimes eschalot. A. chinense; A. fistulosum, the Welsh onion – does not form bulbs even when mature, and is grown in the West almost exclusively as a scallion or salad onion. [9] A. × proliferum – sometimes used as scallions [10]
Mushrooms grow well at relative humidity levels of around 95–100%, and substrate moisture levels of 50 to 75%. [1] Instead of seeds, mushrooms reproduce through spores. Spores can be contaminated with airborne microorganisms, which will interfere with mushroom growth and prevent a healthy crop.
A horizontal espalier Free-standing espaliered fruit trees (step-over) at Standen, West Sussex.The trees are used to create a fruit border or low hedge.. Espalier (/ ɪ ˈ s p æ l ɪər / or / ɪ ˈ s p æ l i. eɪ /) is the horticultural and ancient agricultural practice of controlling woody plant growth for the production of fruit, by pruning and tying branches to a frame.
