# Yellow Iris (*Iris pseudacorus*) The Yellow Iris is a beautiful flower with bright yellow petals. It grows near water and adds color to ponds and wetlands, making nature even more lovely! - **Category:** [Plants](https://www.snappit.app/explore/categories/plant) - **Rarity:** Common - **Danger:** 1/5 · Very low - **Snaps:** 93 - **Habitat:** Wetlands - **Also known as:** Yellow Flag Iris ![Yellow Iris](https://commons.wikimedia.org/w/index.php?title=Special:Redirect/file/Iris_pseudacorus_001.jpg&width=800) Photo: Jean-Jacques MILAN, CC BY-SA 3.0 · [Wikimedia Commons](https://commons.wikimedia.org/wiki/File:Iris_pseudacorus_001.jpg) ## Appearance The Yellow Iris has striking bright yellow flowers with three large, downward-arching sepals often marked with brownish-purple veins. Its long, sword-like green leaves grow stiffly upright. These distinct features make it easily recognizable in watery environments. ## Taxonomy - **Kingdom:** Plantae - **Phylum:** Tracheophyta - **Class:** Liliopsida - **Order:** Asparagales - **Family:** Iridaceae - **Genus:** Iris ## Interesting facts - A single plant can produce hundreds of floating seeds, spreading far and wide! - Each flower has a special 'landing strip' for visiting insects to guide them to nectar. - It was once planted to purify water in old European sewage systems! - The plant's roots were historically used to make a black dye for textiles. ## Special abilities - **Water Anchor:** Yellow Iris can grow thick, creeping rhizomes that anchor it firmly in saturated soils, helping it survive strong currents. - **Toxic Defense:** Yellow Iris has irritating compounds in its sap and leaves that deter most herbivores from eating it. - **Wetland Colonizer:** Yellow Iris can quickly spread through seeds and rhizomes, allowing it to rapidly colonize new wetland areas. ## Measurements & details - **Height:** 60-150 cm - **Spread:** 30-60 cm - **Flower Size:** 8-10 cm - **Bloom Season:** Late spring to early summer - **Edible:** No - **Toxicity:** Moderate - **Lifecycle:** Perennial - **Pollination Method:** Insect ## Ecological connections - **Pollinates:** European honey bee (*Apis mellifera*) — Visits flowers for nectar and pollen. - **Pollinates:** Buff-tailed bumblebee (*Bombus terrestris*) — One of many bumblebee species pollinating. - **Pollinates:** [Common drone fly](https://www.snappit.app/explore/common-drone-fly) (*Eristalis tenax*) — One of many hoverfly species that pollinate iris. ## Traits - [Flowering](https://www.snappit.app/explore/traits/flowering): Flowering plants are any plants that produce flowers as part of their reproductive cycle. - [Cluster Flower](https://www.snappit.app/explore/traits/cluster-flower): Cluster flowers are inflorescences where individual flowers are arranged closely together on a common stem. - [Summer Blooming](https://www.snappit.app/explore/traits/summer-blooming): Summer blooming plants produce their flowers during the summer season, often providing vibrant color when many other plants have finished. - [Fragrant Flower](https://www.snappit.app/explore/traits/fragrant-flower): Fragrant flowers emit a pleasant aroma, often to attract pollinators or for defense. - [Pollinator Magnet](https://www.snappit.app/explore/traits/pollinator-magnet): Describes plants that are particularly attractive and beneficial to a wide range of pollinating organisms. - [Rapid Growing](https://www.snappit.app/explore/traits/rapid-growing): Rapid growing plants exhibit accelerated growth rates, quickly increasing in size and biomass within a short period. - [Wetland](https://www.snappit.app/explore/traits/wetland): This habitat trait identifies species found in wetlands, which are areas of land saturated with water, either permanently or seasonally, including marshes, swamps, and bogs. - [Aquatic](https://www.snappit.app/explore/traits/aquatic): Aquatic habitats encompass environments where organisms live predominantly in water, including oceans, rivers, lakes, and wetlands. ## Collections - [Plants](https://www.snappit.app/explore/collections/plants) ## Safety **Danger:** 1/5 · Very low Do not touch the leaves or flowers too much, as they can be slippery near water. ## Frequently Asked Questions ### How to identify Yellow Iris? Start with the whole plant, then compare leaf arrangement, leaf edges, stems and any flowers or fruit. Opposite leaves grow in pairs; alternate leaves come one at a time along the stem. These details tell you far more together than a single green leaf does. Plant Identifier: upload a photo and compare the visible details. ### How tall is Yellow Iris? 60-150 cm ### How wide does Yellow Iris spread? 30-60 cm ### How big are the flowers on Yellow Iris? 8-10 cm ### When does Yellow Iris bloom?
