Yellow flag yvavilebi is a variety of Iris with its sepals often decorated with short as well as brown and purple streaks. These flowers are native to North Africa, Asia and Europe after having been introduced first in North America. It generally grows beside the lakes and edges of ponds where there is abundant wet soil and the water level is shallow. Its length can exceed up to five feet but generally they lie within 3 feet height. Drawbacks of yvavilebi They generally form dense stands just above the ground with a thick rhizome mat on the ground. Yellow iris is often sued in beverages. They’re roasted and used for making dyes. The side effect of this plant is that, it’s quite toxic so exposure to it physically will harm its cultivators. It can cause several ailments such as skin irritations, diarrhea, and even vomiting problems. The other drawbacks include their aggressive growth rate. They can thus block the habitats of wild animals and birds besides causing problem to irrigation channels and other drainage facilities. The rhizome mat that grows above the ground can also trap sediments and also change the nature of the habitats. Due to their aggressive growth nature, even a single broken rhizome can develop into a new colony of yvavilebi. The seeds can be easily transported in water and deposited in the nearby channels. Precautionary measures for growth Rebloomers who wish to grow iris twice during the course of year, have to be strategic enough to plant the seeds during the favorable time of the year, when the environmental conditions are apt for growth. For second growth period, the plant is vulnerable, thus it requires a proper care including timely administration of fertilizers and waters to enable it to bloom with effective ease. Some of the times, the yvavilebi fails to grow due to the absence of proper soil cover or use of extra amount of fertilizers. The growth of these plants might also be hindered due to the presence of underground pests. Even planting these seeds into deep soil can inhibit their growth. Excess shade along with low temperature condition can also prevent the flowers from blooming.
