Can Violets can change colors, but do you know how? If you know the secrets behind these changes, you can try. Read below to find out!
Cherished for their colorful blooms, African violets can brighten up indoor spaces like no other flowering houseplant. But have you ever noticed your once purple flowers changing to white or a deep pink variety, or suddenly sporting streaks of blue? If you have, here is the reason!
Can African Violets Change Colors? How?
Yes, African violets can change colors, and it’s more common than you might think. This fascinating phenomenon occurs in both the flowers and, occasionally, the leaves, although you will see blooms undergoing noticeable color changes.
Sometimes, you will see a deep purple African violet fade into a softer lavender. Your pink-flowered variety could develop bold blue streaks, and some white or pale flowers may unexpectedly blush into a delicate pastel shade.
Unique Fact: Interestingly, bicolor varieties sometimes lose their variegation, while others may develop mysterious speckles, streaks, or an entirely different hue.
Fun Part: This color-shifting behavior can become an exciting surprise for you because no two blooming cycles look exactly the same. It will allow you to enjoy a single plant in several different shades throughout the year, almost like having a rotating flower display without buying anything new.
Why Do African Violets Change Colors and How to Achieve It?
1. The Hybrid Factor
African violets are highly hybridized plants, and their genetics can sometimes trigger unexpected changes in flower color. Some hybrids are prone to sporting random genetic mutations, which can cause a once-solid purple bloom to develop white streaks, variegation, or an entirely different color over time.
You will find this common in chimera varieties, which have striped blooms. If you see them suddenly producing solid flowers, the genetic mutation responsible for the stripes has been disrupted.
In the same way, some violets with ruffled, multicolored petals may revert to a single shade due to their hybrid nature. So, if you wish to change, have African violets that change color–grow these varieties.
2. Light Exposure
As a gardener, you should know that light plays a huge role in bloom pigmentation. If you expose your Violets to too much bright, direct light, it can cause deep, saturated colors like violet or dark blue to fade into soft pastel shades.
You will often see this in dark-flowered varieties like ‘Ma’s Ching Dynasty,’ which can lose their intensity under excessive sun exposure.
On the other hand, too little light can lead to washed-out, duller blooms, as the plant isn’t able to produce enough anthocyanins, the pigments responsible for red, purple, and blue colors.
Pro Tip: To maintain the richest colors, keep your African violets in a mix of direct and indirect sunlight.
3. Temperature Swings
Your African violets are highly temperature-sensitive, and sudden drops or increases can trigger unexpected color shifts. When you grow African violets in cooler temperatures, it will intensify blues and purples, while warmer temperatures fade colors or bring out pinkish tones.
You will see some violets naturally shift hues with seasonal changes.‘Optimara EverGrace’, for instance, displays a deeper blue tone in cooler temperatures and a lighter lavender shade when grown in warm conditions.
Pro Tip: Keep temperatures stable, between 65-75°F (18- 24 °C), to preserve the original color.
4. Soil Composition And pH Levels
While not as much as in hydrangeas, soil pH can subtly influence African violet colors. A more acidic soil mix, where pH is below 6.0, can encourage richer blues and purples, while alkaline conditions, where pH is above 7.0, might soften those hues into lavender or pink tones.
You will see ‘Optimara MyDesire’ shift toward a more lavender shade in slightly more alkaline soil. This is because pH levels affect nutrient availability and anthocyanin productivity, which can slightly shift bloom tones.
Fun Tip With Caution: If you want to experiment with color changes, you can slightly adjust your soil pH by adding materials like peat moss to increase acidity or dolomitic lime to make it more alkaline.
5. Stress and Deficiencies
You don’t want to induce this in your favorite flowering plant, but it’s a fact that African violets don’t like change, and when they experience stress, they may alter their bloom color as a response.
If your plant lacks phosphorus or potassium, it produces duller, paler flowers, as these nutrients are essential for strong pigmentation.
In the same way, yellowing leaves and weak blooms in your African violet are often a sign that you are not giving it enough micronutrients like iron or magnesium.
Some gardeners also make the mistake of overfertilization, which can sometimes trigger an intensification of certain hues, especially in pink and red-toned varieties.
For example, ‘Rob’s Vanilla Trail’, which usually has soft creamy-pink blooms, may develop a brighter, more intense pink color when given too much nitrogen-heavy fertilizer.
Watch African violets shift colors so that they add a little mystery and charm to every new bloom cycle with these tips. If you like the article, don’t forget to share it!
