Don’t know any of that stuff, other the it’s Martha Something. It was bought on a whim.
We will see if it even comes up!
It sounds like its probably the Martha Washington variety. It is known for its resistance to asparagus rust, and other issues.
It produces uniform size , thick green shoots with tightly folded purple tips , and is known for heavy yield.
It prefers a rich soil , preferably with good drainage.
Similar to other asparagus varieties , you can expect a good harvest from 3 year plants, with the harvest generally lasting three months from late April through June.
It sounds like your 'whim' was a good one !
