Hi Georgia,

Please take a look at the picture displayed and its description on Wikipedia:

http://en.wikipedia.org/wiki/Asparagus

or, for an enlargement of the picture:

http://en.wikipedia.org/wiki/Image:Asparagus3.JPG

Although the common translation for espárrago triguero is indeed wild asparagus, this is something of a misnomer. While wild asparagus does indeed resemble wheat and despite the logical association of its appearance to 'triguero', I am yet to see wild asparagus on sale in Spanish supermarkets or served in Spanish restaurants as 'triguero'.

What you'll get is the type displayed in the middle, i.e. green asparagus.

For further insight, google pictures for "espárrago triguero" and compare them to the Wikipedia picture.

Good luck!

Álvaro :O)

Sorry, I overlooked the other part of your question. As Cindy rightly pointed out, 'triguero' is a common reference to 'esparrago triguero'.

I would just like to underline that this answer refers to usage in Spain. I can't say how the term is used in other Spanish-speaking countries.

Incidentally, I just checked KudoZ glossaries and found the following entry:

As per Penelope's peer agreement to that question, white asparagus is also sold fresh and, in addition, green asparagus can also be bought in jars or tins.

Green and white asparagus are in fact the same plant, but I believe the difference is actually due to exposure (or not) to light. :O)
