Question: I have iris cristata and want to add another "evansia" (I think) called a Japanese Roof Iris or Tectorum to the bed. The bed is under trees and has alot of shade in summer, will the roof iris bloom in partial shade?
Answer: Iris tectorum will bloom in part shade to full sun, so give it as much sun as you can. It also needs a damp to moist, humusy, acid soil. Enjoy!
