Pacific Coast Irises (PCIs) are part of the Iris genus, grouped under the series Iris ser. Californicae. Their common name comes from the fact that they are native to the West (Pacific) Coast of the United States. They are also known as Californian Irises.
They are small, clump forming, perennial plants with strappy, grass-like foliage, and are ideal for planting on borders, under trees, or in grass gardens.
Pacific Coast Irises are very tolerant of a wide variety of conditions and will grow in full sun to shady areas. They are also tolerant of being planted at the base of pine trees. They need little maintenance, only cutting the foliage to the ground once a year at the start of winter to help keep them looking fresh.
They bloom from October, at the start of the Iris flowering season, and before the Tall Bearded Irises bloom.
