One our all-time favorites and hands down one of the best and most profuse blooming Iris you'll ever grow, Caesar's Brother is an exceptionally hardy variety that will grow almost anywhere in the United States (Zones 3a-9b). We've had it growing in our landscape since the late 1980's and it continues to flourish and produce LOADS of flowers. In mid to late spring, deep purple beardless flowers perched atop sturdy stems rise above thick clumps of slender, deep green leaves that remain attractive throughout the season. Truly spectacular in mass plantings. Get all the details below!
