Name: Daisy I Reno, Nv (Zone 6b) Not all who wander are lost
Three plants I can think of that are not mints and do not smell but do have square stems: Loosestrife, Verbena, Stinging Nettle.
That's all I've got.

Life is not a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and proclaiming...."WOW What a Ride!!" -Mark Frost
