Why Do African Violet Leaves Turn Yellow?

African violet (UV) is a powerful yellowish violet (Vitamin C) and the most commonly used vegetable dyes. It has a long history as both a pigment and a dye, with obvious practical reasons for its use in food, clothing and pottery. However it has also had a reputation for having a toxic effect on humans when eaten or swallowed, and this is why there are recommended safe limits for the amount of UV that a person can consume each day. The leaves of the African violet plant contain a substance called anthocyanin, which is responsible for this yellowing effect. In this article we’ll examine why do African violet plants turn yellow and what you can do to avoid eating them.

There are several types of anthocyanins, ranging from red to purple. The anthocyanins which turn colors have a very deep color of purple. One of the more common chemical sources of anthocyanins is grapefruit, specifically the red or purple fruit of the Pitanga variety. In this fruit the outer skin is almost entirely covered in purple skin; this is the source of the popular belief that the fruit itself is purple. Purple grapes are also one of the most expensive varieties, sometimes fetching prices in excess of $1000 a piece.

Although the fruit itself is purple, the foliage tends towards a paler shade, sometimes becoming almost black. The stem can sometimes be pale pink, a defect common in hybrid varieties. The flowers can be pink or white, and have a nearly double stem and often appear as a cluster of multiple flowers. Each flower typically blooms for about four weeks, during which time the foliage will drop to its normal color.. This cycle can last up to two years.

Why do African violet flowers yellow? When the plant flowers the tiny, purple seeds are released, which are then dispersed through the air, normally ending up on the ground. They are very small, about the size of sand grains. After a few days they begin to germinate, and within a week new shoots shoot out. Within eight to ten weeks new roots start to sprout from the base of the shoot and root system of the plant.

African violets, and their hybrids with other species of Violets, are known as “leaves of primrose”. As the name implies, this breed of plant is characterized by a single, long, narrow leaf with a primrose-colored center. As it grows older the center turns more purple. Within the entire litter of leaves the purple color occurs most prominently. This is probably because the flower head is so closely attached to the stem.

Why do African violet (or “primrose” as it is also called in the United States) yellow leaves turn yellow? There are many theories surrounding the cause of this phenomenon. One popular one states that because the flower head is so closely attached to the stem, the color occurs when the tip of the flower gets closer to the ground. Another idea for the reason is that the yellow color is the result of a chemical reaction that occurs when the plant recognizes some form of nutrient, such as iron or calcium.

However, the root causes of the color still remain a mystery to modern scientists. There have been, however, many studies that point to other causes of the color. For example, fungi that grow on the roots of plants appear to have a reaction to the violet color. This could be the reason why young African violets and other breeds of this plant are turning yellow.

Another explanation for the turning of African violet (or primrose) leaves is that the plant has become stressed out. Under these circumstances, the yellow color may be caused by a lack of sugars in the plant’s food supply. Stress causes the plant to make less of a fertilizer, resulting in the lack of nutrients and possible yellowing of leaves. Some African violet growers find that they can increase the amount of nitrogen in their soil, thereby turning their soil more yellow. This method is somewhat effective, but it takes some know how and lots of time to care for the plants properly. But, if you really want an answer to the question, “Why do African violet leaves turn yellow,” you will find that there are some rather simple and natural solutions to the problem.
