The African violet, Saintpaulia ionantha, was found in Tanzania in East Africa by Baron Walter von Saint Paul in 1892. Saintpaulia, the genus, was named after this explorer. Ionantha, the specific epithet, alludes to the violet hue of the blooms. The family Gesneriaceae, which also includes well-known blooming plants like Streptocarpus and Gloxinia, includes African violets. These lovely flowering plants now come in colors more than only violet. Numerous hybrids and variants are now readily available as a result of their popularity. The original plant underwent mutations that resulted in the various flower colors, flower forms, and leaf sizes. Growers propagate the unique plant to create a new variety when a new form is found. Pink, white, mauve, and bicolor blossoms are frequently seen. African violets also have exquisite single or double blossoms that rest atop their smooth, velvety leaves. New miniature types maintain a width of around 4 inches whereas standard plants normally grow to a size of 8 to 12 inches.
Cultivation Information
The basic norm is to give plants 10 to 12 hours each day of bright light. African violets are shielded by the forest’s tree canopy in their natural habitat. Therefore, during the brighter summer months, they require filtered sunlight. Plants may benefit from light acquired from southern exposure during the winter months when the sunlight is less.
According to several experts, artificial light is more reliable and works just as well as natural light. Two 40-watt fluorescent lamps provide the greatest artificial lighting. The ideal daylight tubes are warm-white and cool-white, respectively. These ought to be positioned 8 to 12 inches above the plants. Increase the light if your plant has robust, black foliage but no blossoms. Reduce the light if it is blooming but the leaves are pale.
African violets can thrive in indoor settings. They prefer a temperature of 65 to 80 degrees Fahrenheit with a humidity of about 80%. It’s crucial to prevent changes in humidity and temperature, as well as unexpected drafts. You could wish to use a humidifier or set pots in a tray with water, gravel, and other moss to create a climate that is sufficiently humid. DON’T spray the vegetation. Permanent leaf spotting could result from water on the foliage.
Make use of room-temperature water. African violets are prone to crown rot, therefore it’s crucial to avoid overwatering the crown (the area of the plant that is at soil level). In general, it’s not advised to water the plant from above.
WATERING METHODS
- For 15 to 30 minutes, put the pot in a saucer of water. Through the drain hole in the pot, water will be absorbed by the soil. DO NOT let the pot sit in water for longer than 30 minutes to prevent root damage.
- Wicking mechanism
- When planting an African violet, bury a synthetic rope in the soil and pull it out via the drain hole (natural material will rot). Through this wick, the earth receives water from the saucer. To prevent the dirt from coming into touch with the water in the saucer, add a layer of gravel to the saucer. The plant can take in water as needed thanks to the saucer’s continual water supply. Additionally, this approach can help with overall humidity.
- Self-watering specialty pots
- These pots are made up of an inner, unglazed ceramic pot and an outside, glazed ceramic pot. Similar to the wick method, the inner pot can absorb moisture through its porous walls as needed after being inserted into the outer pot, which is filled with water.
Potting & Soil
Repotting African violets is advised once a year to assist the plants receive fresh nutrients and get rid of salt accumulation. African violets prefer to be loosely attached to their roots. No more than one-third of the plant’s leaf span should be the diameter of the container. For instance, a plant with a leaf span of 12 inches needs a 4 container.
A light soil mixture that enables for sufficient drainage is preferred for African violets. Equivalent amounts of peat, perlite, and vermiculite make for the best mixture. Dolomite lime must be added to most general mixes in order to maintain a pH balance between 6.0 and 7.0. Another choice is to buy an African violet-specific mix from your neighborhood garden center.
Fertilizer
Every time the plant is watered, apply liquid fertilizer at a concentration of half or quarter. The fertilizer’s dilution aids in protecting fragile roots from harm. Find a mixture, such as 20-20-20, that contains the same amounts of nitrogen (N), phosphorus (P), and potassium (K). Local garden centers also provide special mixes for African violets.
Additional Care
Fertilizer salts may assemble in clay pots. The African violet’s leaves and stems may burn and finally decay if they come into touch with these salts. The best strategies to address this issue are:
- Avoid overfertilizing.
- Place a water-resistant barrier between the pot and the foliage.
- Clean the empty pot thoroughly after soaking it in a solution of 1 part vinegar to 3 parts water for the night.
Where should an African violet be placed?
Because they require dry leaves, African violets are only grown indoors in North America. If you want the finest color and flowers, grow your plants in bright, indirect light. The optimal location for a plant stand is three feet away from a window that faces west or south. When placed directly next to north or east-facing windows, plants will still grow, but their leaves will be thin and spindly, and they will be less likely to flower. African violets can be grown indoors, 12 to 15 inches above the ground, under 40-watt fluorescent lights (also known as grow lights), if you don’t have a nice location near a window.
Are humidifiers necessary for African violets?
Although you might consider African violets to be out of date, they are still among the simplest and most rewarding flowering plants to cultivate indoors, and the blossom patterns and colors are virtually limitless. African violets are small enough to fit into any house or workplace, measuring anything from under six inches to over sixteen inches in diameter.
African Violet Light Requirements
African violets require some light; avoid placing them in a dark area and keep them out of the sun. The best window is one that faces north or east. For even growth, flip the plants frequently because they grow toward the light. Under fluorescent lighting, Africa violets also flower exceptionally well. Your plant isn’t getting enough light if it has large, thick leaves and lengthy leaf stalks. Plants that are stunted and have little, crinkled leaves and short leaf stems are receiving too much sunlight.
African Violet Temperature and Humidity
The temperature is important to African violets. The ideal temperature for the night is between 65 and 70 degrees; the ideal daytime temperature is between 10 and 15 degrees higher. On chilly evenings, you might want to move your plants away from the windows unless your windows are well-insulated. African violets don’t like it when it’s too hot or too cold since they turn black and wither. Temperatures exceeding 80 degrees can be made up for with air conditioning, increased humidity, and ideal lighting.
African violets require high humidity to thrive, speaking of which. Pebble trays and humidifiers are used by serious growers. Because the water drops can harm or mark the hairy leaves, misting is not a smart approach to raise the humidity.
Potting soil for African Violets
African violets do well in loose potting soil with a lot of organic matter. The optimum way to irrigate these vibrant plants, which demand a uniformly moist soil, is up for debate among experts. You have three options for watering the soil: from the top, from the bottom (don’t leave the pot in the water for too long or it will rot), or continuously using a wick and reservoir system.
African Violet Propagation
It makes sense to want to share a really lovely African violet when you have one. Individual leaves can be rooted, and multi-crowned plants can be divided to create new plants.

How frequently do African violets need to be watered?
Consider fluorescent lighting. Fluorescent lighting is the solution if you lack bright window light. I make use of four-foot lights that each have two cool white bulbs. I’ve successfully used one warm white and one cool white bulb in a fixture. unique plant bulbs, known as “A beautiful plant is also produced under grow lights. 8 to 12 inches is the ideal distance between the pot and the light.
How frequently should African violets be watered? “The most frequently asked question regarding African violets is how frequently they should be watered. The greatest indicator is to touch the surface of the soil; if it feels dry, it’s time to water. For best results, African violets should be given time to completely dry out in between waterings. An overwatered plant can die. A soggy, moist soil mass prevents air from penetrating the fine roots of an African violet, which they need. Half of your work is finished once you have learned the art of watering African violets.
Do African violets need to be watered from the top or bottom? Both are acceptable. It’s crucial to avoid using cold water; lukewarm or warm water is recommended. To prevent leaf spots, if you water from the top, take cautious not to get water on the leaves when the plant is in the sun. If you water from the bottom, you should dump any extra water once the plant has absorbed all that it requires. An African violet shouldn’t be left submerged in water for too long.
Is it better to water African violets from the top or the bottom?
Use only water that is room temperature because African violets are sensitive to temperature. Avoid soaking the plant’s fuzzy leaves or stem since water might get trapped there and lead to rot or fungus.
Watering an African violet plant is most effective when done from the bottom up. For 30 minutes, submerge your plant in a small tray of water and let the soil absorb the moisture through the drainage holes in the bottom of the pot. To prevent the roots from being soaked in water, let the pot drain in your kitchen sink or bathtub once the allotted time has passed. This will prevent root rot.
When 25% of the soil volume has dried out, Pangborn advises watering to maintain the soil continuously moist.

About African Violets
African violets, as their name suggests, are indigenous to East Africa and come from the subtropical rainforests of Tanzania and Kenya. German colonial commander Walter von Saint Paul-Illaire recognized these plants in 1892 and returned to Germany with seeds. Saintpaulia became the name of the genus, although Streptocarpus, a new genus, has lately been assigned to the plants. They are not a species of violet, despite their common name, but they do have bright violet blossoms. Here is more information on these delicate plants.
In bright, indirect light, African violets flourish and produce the greatest blooms. Despite being typically easy to care for, they occasionally have fussy periods. Be not disheartened!
How to Plant African Violets
- If the soil is well-draining, you can use an authentic African violet potting mix or an all-purpose potting soil. How to make your own blend is shown here.
- African violets should always be grown in small pots, and every few years they should be repotted with new soil. African violets blossom more when they are somewhat constrained by their pots, so don’t be hasty to give them more room.
- The soil should have a high organic matter content and be loose and well-drained. discover organic soil amendments.
- African violets should not be replanted deeper than they were previously and the plant’s crown should not be buried. If kept overly damp, the stems of African violets are prone to rotting.
Watering
- Maintain a light moisture in the soil, but watch out for overwatering because African violets’ fragile stems are highly prone to rot.
- Use room temperature water instead of chilly water because the leaves may become marked.
- African violets should only be watered from the bottom to prevent getting too much water on the leaves, which can rot and develop fungal patches if kept in an environment with excessive humidity.
Lighting
- Bright, indirect light is preferred by African violets. Keep them at least a few feet away from bright south or west-facing windows and stay out of direct sunshine. The greatest illumination for them comes from a window that faces east or north without endangering the delicate leaves.
- Artificial illumination also functions nicely. Use LED or fluorescent lamps in addition to natural lighting.
- Leggy stems and thin, dark green leaves suggest that the plant is receiving insufficient light, while light green or bleached leaves show that it is receiving too light.
Fertilizing
- Use a high phosphorus plant food to fertilize every two weeks during the active growing season (spring and summer). Only begin fertilizing when it looks that the plant requires an extra push (slow, thin growth; pale or yellowing leaves).
- Since most soil mixtures already contain an abundance of nutrients, overfertilizing is an issue that occurs more frequently than underfertilizing.
General Care
- Some kinds are more tolerant of cooler circumstances, but many prefer warm environments (65F/18C or warmer). In any event, avoid having them near drafty windows during the winter.
- As they get bigger, plants should be moved to bigger containers, although keeping African violets slightly root-bound might help them blossom. Wilted leaves are one indication that your violet needs to be replanted.
- The squishy leaves have a propensity to gather dirt and dust. Use a little paintbrush with sensitive bristles to gently scrub them away.
