Iris seriesCalifornicae are a series of the genusIris, inIris subg.Limniris. They are commonly known asPacific Coast iris (PCI),[1] or Pacific Coast natives (PCN).[2]
The series was first classified byDiels inDie Natürlichen Pflanzenfamilien (Edited by H. G. A. Engler and K. Prantl) in 1930. It was further expanded byLawrence in 'Gentes Herb' (written in Dutch) in 1953.[3]
They all possess thin wiry, rhizomes and roots. They also have narrow, long evergreen leaves.[1] Which are leathery and deep green.[2]
The plants have unbranched flower stems that bear 2 or 3 flowers. The plants do clump quickly and produce many stems.[1] They prefer acid soils. (all except 'Iris douglasiana', which prefers alkaline soils).[2] In the wild, all the species are located on soils on slopes with good drainage. They grow at the edge of woods. They do not like root disturbance, so can be difficult to cultivate for the gardener.[4][1] They can be grown in large clay pots in the UK, to be able to protect them in the winter.[2] or they could be grown from seed, to stop root disturbance.[4] Most flower between mid spring to early summer.[1] April to June (in the UK).[2] The leaves can turn red in the autumn.[5] They have been used to create various hybrids, mostly in America.[2]
They come from the west coast of USA, native toCalifornia,Oregon, andWashington. They are mostly dwarf in size and flower in early summer. They vary in colour depending on the species.[1]
