Full sun, good drainage for asparagus. I have mine in a 4x8’ raised bed. I DEARLY miss my 40’ row of it at my other farm. That ALONE was worth the purchase price when I sold, LOL!
You could put it in with your roses. It would look very pretty with them when ‘fronded’ out, but anyone in your HOA that knows gardening would spot it. Just play dumb, LOL!
It also needs a good 3 years to be well established before you cut it, so time’s a-wastin’! ;)
