Will the 'real' shamrock, please stand up.
Lesser Trefoil: Trifolium dubium.... Seed available on request. this plant is the real commercial Shamrock, but not the real real shamrock. 

St Patrick was suppose to have first used wood Sorrel, and since it rarely produces much seed and is better propagated by root cuttings we don't have it in our seed stocks, then again there is also water cress, which in some parts is considered the real shamrock.

Scientific classification: Shamrocks belong to the subfamily Papilionoideae, family Fabaceae (formerly Leguminosae). 
All fix nitrogen and benefit wildlife and the soil. 
Bees like these plants as they provide nectar, Bumble bees are very found of clovers.

The white clover in your lawn, is classified as Trifolium repens and the hop clover as Medicago lupulina, which is Meddick and not clover at all, at all, at all.

The real Shamrock is Trifolium dubium.   Common names:
Lesser Trefoil, sometimes called Lesser Yellow Trefoil, or the Small Hop Suckling Clover or even the Hop Clover, occasionally called the Least Hop Clover which is actually Trifolium minus. 
So when we say shamrock other say Trifolium dubium = Small hop clover; Suckling clover; Lesser yellow trefoil; Low hop clover; Yellow clover,  So its called Shamrock. Thats that, or is it........
DBN collected a lesser form of Trifolium Dubium, this smaller seaside species is what we call the real shamrock.

Black Meddick Medicago lupulina is also a Shamrock, so is White clover / trifolium repans, not found on this web site, nor should white clover be found in your new wildflower meadows as it smothers wildflowers in new meadows. Sometimes Birdsfoot Trefoil Lotus corniculatus is used as a Shamrock, and Alexanders Smyrnium olusatrum (the Shamrock of the monks in Medieval Ireland.).

Why did Aer Lingus take the shamrock logos off the tail of all its airplanes?, Because they saw the shamrock symbol as 'down market'. in the USA the Irish Scene was considered downmarket in the late1990's.

Yet today Shamrock is seen as the luckiest plant in the world and is found in every casino in the galaxy..... that's why we want to find a four leaved clover, for our customers, and contrary to believe and what the world wide web says as yet there isn't one,, so get looking, we will pay €10,00 if we can reproduce it from seed, provided it reproduces from seed. Sorry to be so crass, but we have customers who require a four leaved clover.

Clover and Shamrock is susceptible to following diseases : see page http://image.fs.uidaho.edu/vide/famly078.htm#Trifolium dubium,  

Alfalfa mosaic , Bean leaf roll , Peanut stunt, cucumovirus , Soybean dwarf luteovirus, Rust and smut fungi are well-defined groups of plant pathogens. These groups generally are considered to be closely allied with one another and therefore are frequently discussed together. Both groups of fungi are known to cause major crop diseases and are well known throughout the world from the standpoint of their economic significance.

Can Shamrock be exported to USA? and outside EU?
Yes, As seed and plant and only if disease free. or No if from a country with the above diseases, but if isolated in a glasshouse and is disease free, it can be exported as long as it has a phytosanitary cert.
