The Monstera adansonii, often recognized as the Swiss cheese plant, is a popular choice for indoor plant enthusiasts. Its appeal has grown with the emergence of variegated forms, which display striking color variations beyond the typical green foliage. These rare plants feature unique patterns, making them highly sought after by collectors.
Understanding Variegation in Monstera Adansonii
Variegation in Monstera adansonii stems from a genetic mutation that affects the plant’s ability to produce chlorophyll in certain leaf areas. This results in patches or sections lacking green pigment, revealing colors like white, cream, yellow, or light green. This is chimeral variegation, meaning the plant contains distinct genetic sequences within its tissues, with some parts producing chlorophyll and others not. Patterns vary significantly, appearing as splotches, streaks, blocks, or marbling. The distribution and intensity of these non-green areas depend on how the mutation expresses itself.
Popular Variegated Monstera Adansonii Varieties
Monstera Adansonii Albo Variegata
The ‘Albo Variegata’ is one of the most recognized and desired forms, featuring stark contrast of pure white or creamy sections against deep green leaves. Variegation can manifest as large blocks, delicate splashing, or a “half-moon” effect. The white patches lack chlorophyll, meaning these areas cannot perform photosynthesis, requiring the green portions to work harder to sustain the plant.
Monstera Adansonii Aurea Variegata
Another captivating variety is the ‘Aurea Variegata’, distinguished by golden-yellow or lime green variegation. The yellow hues appear as vibrant marbling, streaks, or splashes across the green foliage. The intensity and pattern can differ, with some new leaves emerging bright yellow that may fade to cream.
Monstera Adansonii Mint Variegata
The ‘Mint Variegata’ offers a more subtle yet appealing form, characterized by pastel green or mint-colored patches. This variety often presents a unique blend of light green shades against darker green, sometimes interspersed with white. The minty tones provide a soft, ethereal appearance. Its variegation pattern is generally unpredictable.
Caring for Variegated Monstera Adansonii
Caring for variegated Monstera adansonii requires specific attention, as non-green portions are more delicate and less efficient at photosynthesis. Adjustments to standard Monstera care are important to maintain their patterns and health.
Light Requirements
Variegated Monstera adansonii thrives in bright, indirect light, crucial for maintaining variegation intensity. Direct sunlight should be avoided, as it can scorch delicate white or yellow sections. Provide 8 to 12 hours of bright, filtered light daily, perhaps from an east or north-facing window, or by using sheer curtains. These plants need more light than their non-variegated counterparts due to less chlorophyll.
Watering Practices
Consistent watering is important, but overwatering leads to root rot. Water when the top 1 to 2 inches of soil feel dry. The plant prefers consistently moist but never soggy soil. Allow excess water to drain completely to prevent waterlogging.
Soil and Potting
A well-draining, airy potting mix is important to prevent water retention. An ideal blend includes orchid bark, perlite, coco coir, and compost, providing aeration and drainage while retaining moisture. Repotting every one to two years, or when the plant outgrows its container, allows for fresh soil and healthy root development.
Humidity and Temperature
These tropical plants flourish in high humidity, ideally between 60% and 80%. Low humidity can cause variegated parts to brown or crisp. Using a pebble tray, a humidifier, or grouping plants together can help increase ambient humidity. An optimal temperature range is between 65°F and 80°F (18°C to 28°C). Protect the plant from cold drafts and sudden temperature drops.
Fertilization
During the active growing season (spring and summer), variegated Monstera adansonii benefits from regular fertilization. A balanced liquid fertilizer, diluted to half strength, can be applied every four to six weeks. Fertilization should be reduced or stopped during fall and winter when growth slows.
Common Challenges and Solutions
Variegated Monstera adansonii can present unique challenges.
Loss of Variegation
Loss of variegation, where new leaves emerge green or existing ones revert, is common. This often occurs due to insufficient light, as the plant prioritizes chlorophyll production. Ensure the plant receives bright, indirect light. Pruning any fully green stems back to a variegated node can encourage more variegated growth.
Browning or Crisping Leaves
Delicate variegated sections are susceptible to browning or crisping. This can be caused by low humidity, direct sun exposure, or over-fertilization. Increase ambient humidity, adjust light exposure, and ensure proper fertilizer dilution to prevent this.
Slow Growth
Variegated plants generally exhibit slower growth than all-green counterparts. This is because white or yellow sections lack chlorophyll and do not contribute to photosynthesis, reducing the plant’s energy capacity. Optimal light and consistent fertilization support new growth. Offering a moss pole or trellis can encourage larger leaf development and faster growth.
Sourcing and Understanding Value
Variegated Monstera adansonii varieties are rare, contributing to their higher price. Their unique aesthetic and the challenge of consistent variegation in propagation make them highly sought-after. Value is influenced by rarity, amount and stability of variegation, and overall health and size. Reputable online plant shops, specialized nurseries, and plant enthusiast communities are common places to find these specimens.
