Some similarities to :
- Ramsons (Allium ursinum) for that too has triangularstems (but they are isosceles triangles, rather than the right-angled triangles of Three-cornered Garlic).
Ransoms have broader and lanceolate leaves, and flowers that are not
Daffodil-shaped. The flowers lack a green stripe on the petals.
- Few-Flowered Garlic (Allium paradoxum) but that has square stems, fewer flowers and, lacking a longish conical section to the flowers, with the flowers more abruptly flared.
Slight resemblance to : many other
Garlic species flowers.
No relation to :
Three-cornered hat [a Ballet by Falla] nor to Three-Nerved Sandwort nor
Three-lobed Crowfoot [un-related plants].
Inhabits dampish places where it is warmer in Winter (the last few winters in the UK (2009 - 2012) must have been problematic for it). Considered a problem plant in some areas where it spreads un-controllably. Occupies mainly southern parts of the UK, mainly within 50 miles of the sea, with far fewer inland locations. The proximity of the sea keeps it warmer in winter and more able to propagate.
The flowers are all initially en-wrapped within two white papery bracts, which open to reveal between three and 15 drooping trumpet-shaped flowers on stalks that are longer than are the flowers. Like all alliums, grows from a bulb. The fruit is green, between 4mm and 6mm across and globular. The seeds within are black, oblong and between 2mm - 3mm long.
When damaged, smells of garlic. Both leaves and bulbs can be eaten, although they are moderately poisonous if eaten to excess, especially to dogs.
Like many Allium species Three-Cornered Garlic contains
Cystein Sulfoxides such as Methiin, Alliin, IsoAlliin and
Propiin, with the first three dominating.
S-Methyl-L-Cystein Sulfoxide) is a non-proteinogenic amino acid (NPAA) which can mimic the real amino acid Cystein. Methiin and
S-Propyl-L-Cystein Sulfoxide) are both substances which occur not only in the Alliaceae family but also in the Brassicaceae plant family.
The base of these Cystein Sulfoxides is Cystein (sometimes spelled Cysteine), a sulfur containing amino-acid absent from many mammals and only semi-essential to their well-being, for instance when they are infants, old or un-well; they obtain it from eating foods containing Methionine such as
Brussels Sprouts, and in milk, eggs and many meats.
Cystein(e) should not be confused with
Cystine, which is the oxidized dimer of Cysteine which functions biologically both as a site of redox reactions and as a mechanical linkage in proteins in order for them to retain their 3-D structure which is vital for them to preserve their function. [Neither Cystein nor Cystine should not be confused with Cytosine, a
Pyrimidine derivative and one of the four main DNA bases to be found in both RNA and in DNA]. Cystine is a dimer consisting of two fused units of Cystein, the result having been partially oxidized. Cystein, as far as the Author is aware, does not occur in plants (not even in Three-cornered Garlic), but does in mammals.
