I really think it depends on where you live as to how you treat your brugs to sun or not. Most brugs will do very well with morning sun and afternoon shade. There are some that will do well for me with all day sun and many won't, especially when it gets into the mid to upper nineties. Safety generally wins out here and most go into partial shade. Maya, Bad Angel, Rubirosa, Day Dreams, and Painted Lady can handle our heat and full sun. I think you just have to find someone who has had experience with brugs in your zone or grow them in pots so you can test them out.
In the past I had Charles Grimaldi, Dr. Suess, and Butterfly in full sun too.
