Rhododendron campanulata ssp. aeruginosum is a wild species rhododendron found in the Himalayan alpine regions of Northern India, Bhutan, and Nepal. It grows on the stony alpine slopes and ledges at altitudes of 12,000 to 14,500 feet. Rhododendrons are part of the heath family, like blueberries, cranberries, and heathers.

The evergreen, leathery leaves of

this plant can be as small as 1/4 of an inch, to over three feet in length. Their shapes can be very rounded or long and thin. The leaves grow alternately on the stem. The upper surface is dark green and glossy, while the undersides are fuzzy. The undersides are called indumentum, and can have many colors. Some are cinnamon colored while others are silver to white. R. campanulata ssp. aeruginosum is a low growing form of rhododendron, usually rounded in shape, and up to 4 feet tall. The leaves, which are 3 to 4 inches long, have a beautiful blueish metallic shine to them. Their indumentum starts out whitish when the leaves are young and turn a fawn color as they mature.

Rhododendron flowers grow in large trusses, or clusters, which can be up to 10 inches across. Each flower is shaped like a small bell about 1 - 1.5 inch long. They bloom from spring to early summer, and may be pink, white, red, purple, yellow, orange, or various shades of each. The flowers of Rhododendron campanulatum ssp. aeruginosum are a pink to purple color with some dark blotches.

There are over 900 different species of rhododendrons all over the world. Most of the species are found in Southeast Asia, from the Himalayas through Tibet, China, Thailand and Vietnam, to Malaysia, Indonesia, Phillipines and New Guinea.

Species rhododendrons live naturally in the wild, which means that man hasn't interfered with the way they grow or look. The wild rhododendrons are found from sea level to 19,000 feet in elevation, and grow in many different habitats, including alpine regions, coniferous, and broadleaved woodlands, and even rainforests. They can grow from a few inches high to as high as 100 feet. The first of many rhododendrons which came from Asia was discovered by Captain Hardwicke in 1799. R. campanulatum was brought to England in 1825.

All parts of this plant contain a poison called grayanotoxin, but the leaves are the most poisonous part. Eating this plant can give you a severe stomach ache. It can also cause liver damage and pneumonia. If you have grazing animals, it is important to keep them away from your rhododendrons.

In the Himalayas rhododendrons are often found at the same elevation as the summer grazing pastures. Wood from the rhododendron is used for firewood and building materials by shepherds. Large stands are often clear cut, which leads to major soil erosion. Many areas where rhododendron forests used to grow no longer exist.

The Importance of Plants

Close to 2.5 billion years ago, the earth's surface and atmosphere were stable enough to support primitive life. Single-cell organisms began to develop in the seas that covered the planet. A simple organism known as blue-green algae appeared and spread across the seas. Blue-green algae used sunlight and water to make food, and in the process, created oxygen. As the blue-green algae grew in the earth's seas, they began to fill the atmosphere with oxygen. The oxygen that blue-green algae produced made it possible for other types of organisms to develop.

Plants play the most important part in the cycle of nature. Without plants, there could be no life on Earth. They are the primary producers that sustain all other life forms. This is so because plants are the only organisms that can make their own food. Animals, incapable of making their own food, depend directly or indirectly on plants for their supply of food. All animals and the foods they eat can be traced back to plants.

The oxygen we breathe comes from plants. Through photosynthesis, plants take energy from the sun, carbon dioxide from the air, and water and minerals from the soil. They then give off water and oxygen. Animals and other non-producers take part in this cycle through respiration. Respiration is the process where oxygen is used by organisms to release energy from food, and carbon dioxide is given off. The cycles of photosynthesis and respiration help maintain the earth's natural balance of oxygen, carbon dioxide, and water.

Leaves are the main food-making part of most plants. They capture energy from sunlight, and turn water and carbon dioxide into sugar and starch. This sugar and starch becomes the food that provides plants with energy to grow, to produce flowers and seeds, and carry on their other life processes.


Plant Facts

Scientists believe there are over 260,000 species of plants. Some plants are so small they can barely be seen. Others are taller than people or animals. One of the largest living plants on the earth are the sequoia trees of California. Some stand over 290 feet (88 meters) high and measure over 30 feet (9 meters) wide.

Certain characteristics of plants set them apart from other living things. Both plants and animals are complex organisms that are made up of many types of cells, but plant cells have thick, rigid walls that consist of a material called cellulose. Animal cells do not have this material. The cellulose enables plants to stand upright without the aid of an internal or external skeleton.


Plants and Their Environment

Plants require a reasonable level of heat to grow. The most favorable temperature at which photosynthesis takes place ranges from near freezing to 20 to 25° C (70 to 80° F). The rates of photosynthesis and respiration increase with rising temperatures. Any temperatures above or below these levels limit plant growth. The climate of a region determines what types of plants can survive in that region.

A plant's environment is made up of many factors. One of the most important is the weather--sunlight, temperature, and precipitation (rain, melted snow, and other moisture). Soil and other plants and animals that live in the same area are also included in the environment of a plant. All these factors form what is called a natural community.

No two natural communities are exactly alike, but many resemble one another more than they differ. Botanists divide the world into biomes--natural communities of plants, animals, and other organisms.
