Nope, shouldn't be. I'd grow the rust resistant types. Jersey knight seems to be the most common one i see.

I moved last year and so I just planted my 1 year old jersey knight crowns 2 weeks ago, they are already sending up spears. Prepare a good deep bed (18 inches deep) with lots of organic matter. If you plant 1 year crowns do not harvest any spears this year and only a few next year. Let the stalks grow to help establish a strong root system and don't cut them back till after a good frost kills them.
The jersey knight strain is all male plants so they dont waste energy trying to go to seed and because it wont set seed it wont self sow and overcrowd your bed.

any other asparagus tips? thinking abt growing them for someone else.
