Iris pseudacorus aka Yellow Flag

Yellow Flag should be watered regularly, allowing the soil to dry out between waterings.

Yellow Flag is very sensitive to dry soil. To ensure your Yellow Water Iris is thriving and blooming, choose a potting soil that retains moisture. A good soil should still allow for adequate drainage and contain lots of organic matter. Coco coir or sphagnum moss are great soil additives that will help to retain moisture and provide your Yellow Iris with the nutrients it needs for healthy growth. Make sure to mix these soil additives into the potting soil before planting and water the soil thoroughly. By providing your Yellow Flag with a well-draining, moisture-retaining soil, you can help to maximize its growth and keep it blooming.

To ensure optimal growth, the Yellow Flag prefers bright diffused 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.

Yellow Flag is poisonous if ingested. We suggest keeping this plant out of reach if you have children, cats, or dogs in the home.

The Yellow Flag should be repotted when it has doubled in size or annually, whichever comes first. Providing fresh potting soil with all the essential nutrients each year ensures the plant's well-being, eliminating the need for fertilizer. Remember, plants derive their energy from the sun and not fertilizer.

The Yellow Flag is characterized by clumping growth, with new shoots emerging from the soil around the primary plant.

Yellow Flag’s native range is Europe, including Britain, from Norway south and east to N. Africa the Caucasus and W. Asia.
