I’ve got a spot in the new garden that should work for the rhubarb. There’s one there now that I transplanted last year and it seems to be very happy so far. That spot gets some shade after 2:00pm-ish during the summer.
I bought five different varieties of asparagus - 10 roots of each. It’s going in the ground - there’s no space for a planter box in the spot where it will be planted.
I would never suggest anything else.
Rhubarb; Good! Strawberry rhubarb pie is an excellent pie! (Or crumble, or cake, etc!)
