আমাদের চোখের সামনেই থাকে, কিন্তু কখনো চোখ মেলে দেখা হয় নাই...

Kachuripana(কচুরিপানা) or Water hyacinth flower is one of my favorite flower. Kochuripana plant can be unwanted and exasperating to people, but when the flower blooms, it just looks spectacular. This water plant is from the family Pontederiaceae and the botanical/scientific name is Eichornia crassipes.

This plant was originally from South America, more specifically from Brazil. But later on it just dispersed everywhere somehow. This is a water plant and only grows at water. The root of the plant is black in color, almost looks like beard. This plant has spongy and bulbous stalks that keep them afloat over the water. No matter what the water level rises, it will keep floating. This is a perennial plant having noticeably large glossy leafs.

The flower of water hyacinth is extraordinarily beautiful. This inflorescence flower has six to seven flowers on a single axis, and each flower has six petals and the color of the five petals are from lavender to pink or light blue. Other petal is interestingly different. This one is darker in color, and yellow spot at the middle. It looked to me a plumage of a peacock just painted on that petal. Flower has 3 visible stamens and three smaller stamens inside. It has stigma and ovary too, but I have never seen any seeds of this plant.

Though the flower has sumptuous outlook, but this is the worst water plant ever at the history of earth. This is a very fast growing plant and can occupy a pond or lake within few weeks easily. Later on it becomes impossible to restrain the growth of this water plant. People from around the world are using tons of money for just controlling this invasive water weed. In Bangladesh, we always used to face difficult problems with this plant. For example, during the flood, this plant used to enter inside our paddy fields, but after the flood those remain inside the paddy field to make the life miserable for farmers.

In spite of its noxious attitude, this plant has some benefactors. In Bangladesh, we used to make compost fertilizer using this plant. Since this is widely available inside our water tanks, we can use those easily. Also some crops requires moister at soil. Using this plant around root of the plant we can easily achieve this. We are also using this as fuel at villages during cooking. Some people use to plant this weed at garden for its attractive flowers.

I haven't seen the seed, but it used to produce capsule like seeds. Seed can be dormant for proper environment for up to 20 years. This plant mainly used to propagate through the stolons. It just create a mat over the water surface and make almost impossible to navigate any water vehicles through these.

More of this Hyacinth is available at Wikipedia.

My pictures were captured from Rangamati Lake(রাঙামাটি লেক) during my tour at July 2011.
