Pacific Coast Iris can be dodgy to divide. You have to do it at the exact correct time in the fall just before they grow roots for the new year. Even then it takes a careful and gentle hand to produce viable divisions that will grow on and bloom. Native warrior must derive its name from from its ease of division. Either way its a fantastic PCI that begins blooming in late April and continues almost to June. Red and raspberry colored flowers are dramatic on a very compact plant to just 10″ tall. Grassy evergreen clumps of foliage do not obscure these precious flowers. Full sun to quite a bit of shade in any soil with reasonable drainage, including clay soils. Water for the first season to establish then none in subsequent years. Highly deer resistant. Long lived. Do not disturb once established. Neglect is its friend.
