when i get in this fact scenario ...

i see that the issue is processing enough water.. to offset the high heat of the HOT PART OF THE DAY ...

as with any 'flowering' plant.. the most sun it can get is best.. but in this case.. tempered by avoiding the high heat of the day ... where it might 'burn' more water than it can pump in sun ...

so i would look for a spot that it will be in shade from say.. 1pm to 5 pm ... otherwise.. as much sun as possible ...

which loosely translates .. as growing it like a hosta. ...

I could grow a lot of things in full sun without issues in my cool maritime climate that would need more shade elsewhere, but The Rocket will wilt in sun between hours of 11-4 no matter how much water its given....learned this when I lost a tree to a storm several years ago. It recovers evenings, but is a definite negative as far as interest to the bed during the day. Completely unattractive.

Well, the area will be shaded from the noon sun by a tree and a building. This is why I consider growing it there. After growing a few hosta, I can say that there's definitely enough light to grow a hosta.
