Mine do best in morning sun on the north east side of the house.
Depends on where you live. I am in zone 9 where it gets super hot and very very dry. Mine are on the north side of the house and go dormant in summer, but grow like weeds the rest of the year.
Mine do best on the North East side of my home.
All though some can take full after noon sun. The ones that have thorns versa smooth leaves.
I have mine in direct sun, zone 7b, and they thrive.
