Saintpaulia commonly referred to as African violet is native to Tanzania and Kenya.
African Violets are also native to the most tropical places in the world. You do not typically grow these from a seed.
Most people grow them by cutting part of the plant and using pieces to grow a new plant. Because you do not usually use a seed, some species are slowly becoming endangered because they are being cleared for agriculture purposes.
They typically grow between two and five inches and grow wider than one foot, so they do not take up much room. The flowers on African violets bloom in violet, purple, pale blue or white. They grow better in warmer climates because the too much cold weather can make the leaves lose their color.
Violets have been used to represent mothers and motherhood. Whenever a woman is expecting or after she has had a baby, they are given as gifts in many cultures around the world. Because of their bright colors, they are also linked with Easter and Valentine’s Day. They should occasionally be watered not letting the roots get dry. They should even not be replanted in a more significant pot because they grow best when their roots get crowded. They do need moderate light to grow correctly, but it does not need to be direct light. If grown inside, then they will need to be rotated every week. Each section requires the same amount of sun to avoid one side from growing larger than the other. The only pests that bother these plants are the mealybug.
However, if grown inside and cleaned monthly than these pests can easily be avoided. They do need to be “fed” with fertilizer once a month to help with blooming. Violets can be grown at any time of the year because you can cut leafs and grow a new plant. They also need humidity to grow. One day to add moisture to the air when they are growing inside is to spray warm water in the air around the plant. It adds just enough humidity to promote growth. However, if they are growing outside in a tropical region, then you will not have to worry about this. These plants do need a particular type of soil to grow properly. However, it can be purchased or made yourself.
