What is Variegation in Houseplants?

Variegation in houseplants refers to the patterns and colours found in some parts of certain plants, such as in their foliage, that are often plain green. This striking feature arises for various reasons, including genetic mutations or environmental influences that change the normal creation of chlorophyll in plants, this is the pigment responsible for the green colour in plants.

In Short: Plants get their green colour from chlorophyll. When there's no pigment in the chloroplast, leaves turn white. This happens because of glitches in the plant's chloroplast-making process. These hiccups can pop up anywhere in the plant's DNA or just in certain spots.

By studying the science behind variegation, we can see how genetic changes, growing conditions, and cultivation methods all work together in complex ways to give rise to this phenomenon. Genetic mutations can happen on their own, which can change how the genes that make chlorophyll are expressed. Light intensity, temperature changes, and the availability of nutrients are further environmental factors that can affect variegation patterns in foliage.

These disruptions can cause areas of the leaf to lack chlorophyll, resulting in the appearance of various pigments such as anthocyanins or carotenoids, which produce colours ranging from white and yellow to pink and red. The Red Nerve Plant serves as an example of this. 

The rarity of variegation adds to their allure, making them prized possessions among enthusiasts and collectors. While some variegated plants occur naturally, techniques like Tissue Culture (TC) enhance their likelihood, adding to their desirability and diversity. For example: Alocasia produced from TC are more likely to come out variegated. By subjecting plant tissues to controlled laboratory conditions, tissue culture techniques can induce genetic variations that can promote variegation.

Why Do Plants Become Variegated in Nature: Unravelling the Mystery

As discussed above, a combination of genetic mutations and environmental factors is what causes variegation in plants. While the exact evolutionary reason for variegation is unknown, it is thought to provide some natural advantages. Variegated foliage, for example, can help plants adapt to their surroundings by providing camouflage, deterring herbivores, or increasing photosynthesis efficiency in low-light conditions.

Variegation is not found in all living things; plants are the most common examples. This phenomenon results from plants' unique biology, specifically their reliance on chlorophyll for photosynthesis. While colour variations in animals occur for a variety of reasons, variegation in plants is a specialised adaptation that demonstrates the plant kingdom's remarkable diversity and adaptability.

                            What are the causes of Variegation in Houseplants?

                            Here, we'll zoom in on what makes plants get all variegated and funky. We'll check out how different things stir up the mix and create those cool leaf patterns.

                            Environmental factors

                            Light Intensity
                            When plants receive uneven sunlight, they may develop a variety of colours or patterns on their leaves. This occurs because different parts of the plant produce different amounts of chlorophyll based on the amount of light they receive, giving leaves their green colour. So, when some parts receive more light than others, they produce more chlorophyll, resulting in more green leaves, whereas the opposite is true for leaves exposed to less or lower levels of light!

                            Temperature Fluctuations
                            Plants respond to extreme temperature swings in a variety of ways, one of which is to produce variegated leaves. Why? Well, when temperatures go haywire, plants get stressed out. As a survival strategy, they produce more or less chlorophyll, the green pigment found in leaves. This can result in unusual patterns in the leaves due to varying amounts of chlorophyll production in different parts of the plant.  

                            Nutrient Imbalances
                            When plants do not receive the proper nutrients or they are unevenly distributed within the plant, particularly nitrogen, phosphorus, or magnesium, they struggle to produce enough chlorophyll. This can cause patterns in the foliage because certain parts of the plant receive more or less of these essential nutrients. Variegation occurs as a result of nutrient tug-of-war within the plant. This could be an indication that your plant requires a more balanced diet.

                            Viral Infections
                            Certain viral infections in plants can mess with chlorophyll production and distribution, causing variegation. These viruses disrupt normal plant processes, affecting how chlorophyll is made and moved around. Some viruses even hijack plant cells to produce abnormal pigments, leading to unique colour patterns. So, when you see variegated leaves, it could be nature's way of signalling a viral infection. It's like a botanical mystery novel, with viruses playing the role of mischievous plot-twisters! 

                            Ultimate Guide to Variegation

                            Genetic Mutations

                            Consider your plant's DNA to be a recipe book, complete with instructions for producing chlorophyll, the green pigment found in leaves. Sometimes a random change occurs in the DNA, such as a typo or a missing ingredient in a recipe. These changes are referred to as mutations. One common type is a somatic mutation, which occurs in individual cells rather than the plant's reproductive cells.

                            These mutations can mix up the chlorophyll recipe, causing some parts of the plant to produce more or less chlorophyll in those parts. As a result, you will notice changes in the colour patterns of the leaves. It is like mixing icing for a cake and adding colour but not thoroughly mixing it in, resulting in patches of different colours because some cells contain chlorophyll while others do not or have less.

                            So, if you notice variegation in your houseplants, it could be due to these sneaky mutations causing a colourful chaos in their DNA recipe. 

                            Different Cultivation Techniques that cause Houseplant Variegation

                            Cultivating variegated plants is a great way to produce more of the same mutation! It starts with finding plants that have naturally occurring mutations, which can happen because of genetic changes or environmental factors like sunlight or temperature. Once these special plants are discovered, growers use methods like cuttings or tissue culture to make more of them.

                            WHAT IS TISSUE CULTURE
                            Large-scale growers frequently use tissue culture, a method of propagation that produces plants in a controlled, sterile environment. It allows for the mass production of plants from small pieces of tissue, such as a leaf or stem, under sterile conditions, resulting in genetically identical clones of the original plant.

                            Imagine taking a piece of a variegated plant and giving it a chance to grow into a whole new one—it's like cloning in the plant world! Growers might also breed different plants together to create even more variegated varieties or to introduce variegation to new types of plants.

                            The result? A stunning array of plants with eye-catching patterns and colours that stand out in any indoor or outdoor space. It's like playing with a living canvas right in your home or garden! These variegated plants not only add beauty but also bring diversity to landscapes, making them more vibrant and interesting.

                            So, the next time you admire a plant with funky stripes or patches of colour, remember that it's the result of careful cultivation and a little bit of nature's magic. It's proof that sometimes, imperfections can make things even more beautiful! 

                            Viral infections that can cause variegation in houseplants

                            Below, we’ll briefly look into certain varieties of viruses that cause variegation in houseplants and how to spot them.

                            Tobacco Mosaic Virus (TMV) manifests as mosaic patterns on leaves, interrupting chlorophyll production and resulting in variegation. Symptoms include mottling, stunted growth, and distorted leaves. Infected plants may exhibit yellowing or necrosis (decay). To spot TMV, look for distinctive mosaic-like patterns. It can weaken plants, reduce yield, and render them susceptible to secondary infections.

                            Tobacco Mosaic Virus

                            Cucumber Mosaic Virus (CMV) triggers variegation, leading to mottled or streaked foliage by disrupting chlorophyll distribution in infected plants. Symptoms include yellowing, stunted growth, and distorted leaves. Look for irregular patterns and discoloration. CMV weakens plants, reduces yield, and can lead to severe damage if left untreated. Early detection and management are crucial.

                            Cucucmber Mosaic Virus

                            Houseplants that can get Tobacco Mosaic Virus (TMV) and Cucumber Mosaic Virus (CMV) include:

                            • Spider plant (Chlorophytum comosum)
                            • Peace lily (Spathiphyllum spp.)
                            • Rubber plant (Ficus elastica)
                            • Philodendron (Philodendron spp.)
                            • Pothos (Epipremnum aureum)
                            • Snake plant (Sansevieria spp.)
                            • ZZ plant (Zamioculcas zamiifolia)
                            • Dracaena (Dracaena spp.)

                            These are just a few examples, as TMV + CMV can potentially affect a wide range of plant species. It's essential to practice good hygiene and avoid exposing susceptible plants to potential sources of TMV contamination, such as tobacco products or infected plants.

                            Impatiens Necrotic Spot Virus (INSV) induces variegation, resulting in irregular leaf colouration and patterns. Look for discoloured, decaying lesions on leaves and stems. INSV weakens plants, causing stunted growth, leaf distortion, and reduced flower production. Early detection is key to preventing spread; infected plants should be promptly removed and disposed of to prevent further contamination.

                            This virus primarily affects plants in the Impatiens genus, however can be easily spread to common houseplants.

                            Caring for Variegated Houseplants

                            Variegated houseplants, with their eye-catching patterns and colours, require special care to thrive and retain their distinct appearance. Here's a comprehensive overview:

                            Light Requirements
                            Most variegated plants require the brightest, indirect light possible, with occasional bursts of direct, soft sunlight to keep their colours vibrant. The best positions we have found are in east- or west-facing rooms where the plant will receive soft, direct sunlight for about 1 - 3 hours. Avoid direct sunlight during the hottest parts of the day, as well as placing your plants on a windowsill with direct light, as both can cause leaf burn.

                            Watering Frequency
                            This is plant-specific, and you should always do extensive research on the care requirements for any of your houseplants. However, it is a good rule of thumb to water variegated plants with large sections of variegation slightly less than their green counterparts to avoid brown patches, which are more susceptible to root rot from overwatering. Checkout our Plant Care Guides.

                            Soil Preferences
                            As with most potted plants, drainage is critical. This is especially true for variegated plants. To avoid root rot and brown patches, give your plants a suitable and well-drained potting mix. Be sure to check the basic moisture levels your specific plant requires when choosing your baseline soil. EG: If your plant requires consistent moisture, e.g. Palm Peat is a good choice.

                            KEEP IN MIND: Variegated plants require less frequent repotting compared to common green houseplants due to their slower growth. This results in lusher, happier plants with stable variegation. Remember this when caring for your variegated beauties, as less disturbance means more vibrant and resilient foliage.

                            Temperature Considerations
                            As we now know, temperature can play a vital role in variegation. Consistency is key, so avoid exposing your plants to drastic temperature fluctuations and try to keep them between 18°C and 27°C for the best results. Tip: Avoid windowsills where temperature fluctuations can be extreme.

                            Reversion in Variegated Houseplants

                            Variegated plants pose unique challenges in maintaining their striking appearance. Here are some things to keep an eye out for and what to do.

                            Preserving variegation stability is critically important if you want to keep the plant looking as beautiful as when you received it. Over time, some leaves may return to their original, non-variegated state, this can be normal but might be a sign of something else.

                            To prevent reversion, achieving balance is essential. Avoid extreme conditions, and ensure the plant gets sufficient light and nutrients. Insufficient light or overfertilisation can trigger reversion, causing variegated plants to revert to solid green.

                            Regular monitoring is key. Keep an eye on the plant's growth and coloration, pruning any reverted sections promptly to maintain the desired variegated pattern.

                            By understanding these challenges and implementing appropriate care measures, you can help your variegated plants thrive and retain their unique beauty for years to come. Remember, a little extra attention goes a long way towards preserving their captivating patterns.

                            Reverted from being Variegated

                            Early Signs of Houseplant  Reversion

                            • Changes in Leaf Colour: Watch out for leaves that lose their variegation and revert to a solid green colour. This can indicate that the plant is reverting to its non-variegated form.
                            • New Growth: Pay attention to the appearance of new leaves. If they lack variegation or have less pronounced variegation compared to older leaves, it may signal reversion.

                            Can you get a reverted plant to be variegated again?  No, you cannot reverse reversion; however, optimal conditions such as light, water, nutrients, and pruning may promote variegated growth. However, a full return to variegation is not guaranteed.

                            Excess White Leaf Production in Variegated Houseplants

                            What happens if your variegated plant produces an abundance of white leaves? It could indicate a number of issues: 

                            • Insufficient Light: White or pale leaves may suggest that the plant isn't getting enough light. Variegated plants need bright, indirect light to develop their characteristic colours. Move the plant to a brighter location, but avoid direct sunlight, which can scorch the leaves. This can be the same for leaves reverting to plain green.
                            • Nutrient Deficiency: Variegated plants may require more nutrients to produce vibrant foliage. Consider fertilising your plant with a balanced fertiliser formulated for houseplants. Follow the manufacturer's instructions for application frequency and dosage. 

                            Top Tip: Feed variegated plants at regular intervals as they have less chlorophyll to produce their own energy.

                            • Variegation Stability: Some variegated plants are inherently unstable and tend to produce more white or non-variegated leaves. Prune away excessively white leaves to encourage the growth of variegated ones and maintain the plant's aesthetic appeal as well as it’s health. Plants with an abundance of white leaves can be weaker than their green counterparts.
                            • Genetic Factors: In some cases, excessive white leaves may be a result of the plant's genetics. Certain variegated cultivars may naturally produce more white or pale leaves than others. These are often forms with stable variegation.
                            • Temperature Stress: Extreme temperature fluctuations or exposure to cold drafts can stress the plant, leading to the development of white or pale leaves. Ensure the plant is kept in a stable temperature range.

                            By addressing these potential issues and providing the best possible care, you can help your variegated plant produce a balanced mix of green and white leaves for a stunning visual display.
