Variegated Plants

Have you ever seen a plant with leaves that look like they've been painted? Not the bullshit AI generated garbage littering social media groups, but the natural eye-catching variegated plants that are like nature's own living art! In this Unlikely guide, we'll dive deep into the world of these unique plants and learn what makes them so special (and often painfully expensive). Get ready to discover the science, care, and wonder behind these botanical marvels!

What Are Variegated Plants?

Variegated plants are plants that have different colours or patterns on their leaves. Instead of being all green, they might have patches of white, cream, yellow, pink, red or even purple. It's like the leaves of certain plants felt left out compared to the flowers. This unique colouration isn't just for show – it's a result of fascinating biological processes happening within the plant.

The Science Behind the Colours

So, how do plants get these cool coloured patterns? It's all thanks to something called chlorophyll. Chlorophyll is what makes plants green and helps them make food from sunlight through a process called photosynthesis. In variegated plants, some parts of the leaves have less chlorophyll or none at all. This is why we see different colours.

There are a few reasons why this happens:

Genetic changes: Sometimes, a plant's genes (the instructions that tell it how to grow) get mixed up, causing variegation. This can happen naturally or through careful breeding by plant scientists.
Chimeras: This is when two different types of plant cells grow side by side, creating patterns. Imagine two different colours of paint that don't mix but create a pattern when put next to each other – that's kind of how chimeras work in plants!
Jumping genes: Believe it or not, some genes can move around inside a plant, causing colour changes. These "jumping genes" are also called transposons, and they're like little genetic acrobats!
Mutations: Sometimes, a random change in a plant's DNA can cause variegation. It's like a typo in the plant's genetic instructions that leads to a beautiful mistake!

The Role of Chloroplasts

To understand variegation better, we need to talk about chloroplasts. These are tiny structures inside plant cells that contain chlorophyll. In variegated plants, some cells might have fewer chloroplasts or chloroplasts that don't work properly. This is what creates those beautiful patches of different colours.

Types of Variegation

Variegated plants come in all sorts of patterns. Let's explore some of the most common types:

Edge variegation: The edges of the leaves are a different colour. It's like the leaf has a fancy border!
Sectional variegation: Parts of the leaf are different colours, creating distinct sections. Imagine a leaf divided into different coloured zones.
Marbled variegation: The colours are all mixed up, like a marble cake. This creates a swirling, dreamy pattern on the leaves.
Streaky variegation: The leaves have streaks of different colours, like someone painted brush strokes on them.
Speckled variegation: Tiny dots of different colours cover the leaf, creating a speckled or spotted appearance.
Central variegation: The centre of the leaf is a different colour, often creating a striking contrast with the edges.

Popular Variegated Plants

Now that we know what causes variegation, let's look at some popular variegated plants you might want to grow:

Variegated Monstera (Monstera deliciosa 'Variegata'): This tropical plant has big, split leaves with white or yellow patches. It's a real showstopper and very popular among plant enthusiasts.

Taking Care of Variegated Plants

Variegated plants need a bit more attention than regular green plants. Here's how to keep them happy and healthy:

Light Requirements

Variegated plants generally need more light than their all-green counterparts. This is because they have less chlorophyll, so they need to make the most of what they have. However, be careful not to give them too much direct sunlight, as this can burn their leaves.

Bright, indirect light is usually best for most variegated plants. (250-350 μmol/m2/s)
If a plant starts to lose its variegation and turn more green, it might need more light.
If the leaves start to look bleached or burned, it's getting too much light.

Watering Needs

Proper watering is crucial for variegated plants. They're often more sensitive to overwatering than all-green plants.

Let the top inch or two of soil dry out between waterings, keep grow mix damp.
Use pots with drainage holes to prevent water from sitting in the soil.
Water less in the off season when the plant isn't growing as much.

Soil and Fertilizer

Variegated plants usually grow slower than their all-green relatives, so they don't need as much fertilizer.

Use a well-draining grow mix to prevent water from sitting around the roots.
Feed your plants with a balanced, water-soluble fertilizer during the growing season (for outdoors that's spring and summer).
Use only half the recommended amount of fertilizer to avoid overfeeding.

Pruning and Maintenance

Regular pruning helps keep variegated plants looking their best and encourages more variegated growth.

Remove any all-green leaves or stems, as these can take over the plant.
Trim off any dead or yellowing leaves to keep the plant healthy.
For trailing plants like pothos, regular pruning can help keep them full and bushy.

Humidity and Temperature

Many variegated plants, especially tropical ones, appreciate higher humidity.

Use a warm mist humidifier to increase moisture in the air around your plants.
Keep plants away from cold drafts or heat sources, which can damage their leaves.
If needed, use a plant cabinet to maintain higher humidity

Propagating Variegated Plants

Sharing your variegated plants with friends can be fun, but propagating them can be tricky. Here's why:

The variegation pattern isn't always passed on to new plants grown from cuttings.
Some highly variegated plants grow very slowly, making propagation a long process.
Certain types of variegation, like chimeras, can't be propagated through seed.

Despite these challenges, you can try propagating many variegated plants through stem cuttings or division. Just remember that the new plants might not look exactly like the parent plant!

Myths About Variegated Plants

There are some things people believe about variegated plants that aren't true. Let's clear them up:

Myth: More light creates more variegation.
Truth: While variegated plants often need more light, too much direct sunlight can actually harm them and cause the variegation to fade.
Myth: Variegated plants are less healthy than green plants.
Truth: They can be just as healthy as green plants if you take good care of them. They just grow a bit slower, and for many the variegation browns due to faster chemical decomposition.
Myth: All variegated plants stay the same forever.
Truth: Some variegated plants can change their patterns over time, especially if growing conditions change.
Myth: More fertilizer makes better variegation.
Truth: Too much fertilizer can actually make variegated plants turn more green. Less is often more when it comes to feeding these plants.
Myth: Variegated plants are just a fad.
Truth: People have been cultivating and enjoying variegated plants for centuries. They're not just a passing trend, but certain varieties are very trendy, at least until mass produced!
Myth: Adding silica to soil will maintain or increase white or cream variegation.
Truth: While silica can be beneficial for overall plant health, there's no scientific evidence that it directly affects or maintains variegation patterns. Let's break this down:
- What is silica? — Silica, or silicon dioxide, is a compound found naturally in soil and used by plants to strengthen cell walls.
- Some gardeners believe that adding silica to the soil or using silica-based fertilizers will help maintain or even increase white or cream variegation in plants.
- The reality — Silica does have benefits for plants, including:
  - Strengthening cell walls, which can improve the plant's overall structure
  - Potentially increasing resistance to pests and diseases
  - Possibly improving the plant's ability to withstand environmental stresses
  - However, these benefits apply to the entire plant, not just the variegated portions. Silica doesn't directly influence the genetic or cellular processes that cause variegation.
- The origin of the myth: This myth might have started because silica does strengthen cellular structures and can sometimes make leaves appear shinier or more vibrant. In variegated plants, this can make the contrast between coloured areas more noticeable, similar to varying light levels increasing contrast, but it doesn't actually change the prevalence or variegation patterns.
- What you can do instead: To maintain variegation, focus on providing appropriate light, proper nutrition, and good overall care. Remember, some loss of variegation is normal as plants age or seasons change.
Myth: Variegated plants are unnatural or "fake".
Truth: While some variegated plants are created through selective breeding, variegation also occurs naturally in the wild. It's a real biological process, not an artificial creation.

The Cool Benefits of Variegated Plants

Variegated plants aren't just pretty to look at. They have other benefits too:

Stress reduction: Studies have shown that taking care of plants and being around greenery can help reduce stress and improve mood. Variegated plants often add to plant enjoyment.
Educational value: Variegated plants are great for learning about plant biology, genetics, and how environmental factors affect plant growth.
Increased biodiversity: In gardens, variegated plants can attract different insects and create more diverse ecosystems.
Decorative versatility: The unique colours and patterns of variegated plants make them perfect for adding visual interest to any space, indoors or out.

Why White/Cream Variegation Turns Brown

White and cream variegation in plants primarily turns brown due to a lack of chlorophyll in those areas, which makes them more vulnerable to damage from environmental stressors, particularly light and heat. Here’s a breakdown of the biological reasons:

1. Lack of Chlorophyll: The white and cream sections of variegated leaves contain little to no chlorophyll, the pigment necessary for photosynthesis. Without chlorophyll, these parts cannot convert sunlight into energy, making them more sensitive to environmental factors, such as intense sunlight.

2. Sunburn: Since these areas lack the protective pigments that green sections have, they are more prone to sunburn. The cells in the white or cream regions can become damaged from too much direct sunlight, causing the tissue to break down and turn brown.

3. Dehydration: The non-green parts of the leaf are less efficient at regulating water, making them more susceptible to dehydration, especially in dry or hot conditions. This can lead to cell death and browning of the affected areas.

4. Oxidative Stress: Without chlorophyll, the white and cream areas cannot handle the oxidative stress caused by light exposure as effectively as green areas can. This stress can cause the cells to deteriorate and die, resulting in browning.

This process is a natural response to environmental factors and is common in variegated plants that aren’t given the ideal balance of light and humidity.
