Iris douglasiana aka Marin Iris

Taxonomy

Iris douglasiana, also known as the Douglas iris, is a beardless iris belonging to subgenus Limniris, series Californicae. It is a common wildflower found in the coastal regions of Northern and Central California and southern Oregon, typically growing at lower elevations below 100 meters (330 ft), though it can be found up to 1,000 meters (3,300 ft) high. The plant has a rhizome that is typically less than a centimeter in diameter, with leaves that are about 2 centimeters (0.79 in) wide. It flowers from April to June, producing two or three purplish-blue flowers on each stem, which can range from 15-80 centimeters (5.9-31.5 in) in height. While occasionally white or yellow flowers can be found. In its natural habitat, Douglas iris is most commonly found in grasslands near the coast. However, it can be considered a noxious weed in pastures, as its clumping growth inhibits other vegetation, and its bitter and unpalatable leaves are not suitable for cattle. While Douglas iris is a rare houseplant, it requires regular watering and thrives in direct light less than one foot from a window. It prefers soil that retains moisture and does not require added fertilizers if repotted each time it doubles in size. As a member of the Iris genus, it is native to Southwestern North America.

Common names

Marin Iris, Pacific Coast Iris, Mountain Iris

How to care for Marin Iris

Difficulty

Caring for Marin Iris is a breeze, as it is highly adaptable and forgiving to minor neglect.

Water

Marin Iris should be watered regularly, allowing the soil to dry out between waterings.

Soil

Its needs are relatively simple, but one of the most important is making sure its soil is adequately moist. Without proper moisture, the plant can suffer from wilting and stunted growth. To ensure your Marin Iris is healthy, you must choose a potting soil that retains moisture.

Look for a soil with good drainage to prevent root rot, but also make sure it contains plenty of organic matter. Coco coir and sphagnum moss are both excellent ingredients for retaining moisture and providing the #self.names with the nutrients it needs to thrive. If you can find a soil that has a combination of these ingredients, your #self.names will thank you with beautiful blooms.

Lighting

To ensure optimal growth, the Marin Iris prefers bright indirect light for 6-8 hours each day. Insufficient light can result in slow growth and leaf drop, so it's important to find a well-lit location for this plant. Place it near a window, within a distance of 1 meter (3 feet), to enhance its potential for thriving.

Dormancy

During the cold period, it is common for Marin Iris to go dormant, resulting in a slowdown of growth. To accommodate this, waterings should be spaced out more.

Toxicity

There is no verified data on the toxicity of this plant in the records of Ploi. If any person, including yourself, a family member, or a pet, consume plant material with an uncertain toxicity level, it is advisable to seek the advice of a healthcare expert.

Fertilizer

Repotting the Marin Iris should be done either when it has doubled in size or on a yearly basis, whichever occurs sooner. Fresh potting soil with all the required nutrients, refreshed annually, will provide the plant with all the necessary sustenance, making the use of fertilizer unnecessary. Keep in mind that plants receive their energy from the sun, not fertilizer.

Growth-pattern

New growth will sprout from the top of the Marin Iris as it grows vertically.

Region of origin

Marin Iris’s native range is South-western N. America - California and Oregon.
