Philo Gigas vs. Melanochrysum: At a Glance

The Origin Story

Philodendron Gigas: The Gentle Giant

Philodendron Gigas was only discovered a mere 25 years ago in the lush rainforests of Panama. Native to the lush rainforests of Panama and Colombia, this green behemoth made its home at elevations between 500-1500 meters. Luckily, due to high demand, Philodendron Gigas is now being grown and propagated more widely, making it more accessible (though still somewhat elusive).

• Fun Fact: The name “Gigas” comes from Greek, meaning “giant” – talk about truth in advertising!
• Natural Habitat: Tropical rainforests with high humidity and indirect light
• Discovery Date: 1997 

Philo Melanochrysum AKA Black Gold Philodendron

Philodendron melanochrysum is native to the wet Andean foothills of Colombia. Specifically, it thrives in warm and humid conditions at an elevation of approximately 500 meters above sea level. Its natural habitat spans the provinces of Chocó and Antioquia. While endemic to Colombia, Philodendron melanochrysum has found popularity far beyond its native range.

• Name Origin: “Melano” (black) and “chrysum” (gold) – a nod to its stunning leaf coloration. The name suffix “melanochrysum” translates to “black gold,” alluding to the tiny golden sparkles sometimes visible on the dark, almost black leaves when they catch sunlight.
• Natural Habitat: Cloud forests at approximately 500 meters above sea level.
• Discovery Date: 1886
• Discoverer: Eduard André, a French botanist who probably did a double-take when he first saw those velvety leaves

From Jungle to Instagram Famous

Fast forward to today, and these once-obscure jungle dwellers are now the favorites of the houseplant around the world. They’ve gone from swinging on vines to gracing the most stylish of interiors. It’s like they’ve had a complete lifestyle makeover – from wild jungle inhabitants to sophisticated home decor divas.

But here’s the million-dollar question: How do these jungle natives adapt to life in our homes? Well, that’s where the real adventure begins. These plants are like fish out of water, quite literally. Our job as plant parents is to recreate a little slice of their South American nirvana right in our living rooms. No pressure, right?

Appearance Comparison

Let’s break down their show-stopping features:

Philodendron Gigas

Imagine a plant with leaves so big you could use them as a rain shelter. That’s Philodendron Gigas for you – it’s the plant world’s answer to “go big or go home.”

• Leaf Size: Each leaf can reach up to 3 to 4 feet in size when mature. However, when the leaves are young, they start out much smaller and gradually increase in size as the plant grows taller.
• Leaf Shape: Ovate to heart-shaped, like giant, green Valentine’s cards from Mother Nature
• Leaf Color: stunning shade of deep green, which tends to grow darker as the plant matures. An interesting contrast is achieved when you observe the underside of the leaves, which bear a vibrant shade of burgundy red.
• Petiole: Smooth and green, sturdy enough to hold up those massive leaves. Unlike the typical round petioles found in many plants, the petioles of Philodendron gigas grow in a distinctive D shape. This unique feature sets it apart from other philodendron species.
• Growth Habit: Philodendron gigas is a vining and climbing plant, which means it provides you with plenty of options for how you want to grow it. Consider providing it with a burlap pole or mossy post to encourage its natural climbing behavior.

Philodendron Melanochrysum

If Gigas is the plant equivalent of a power suit, Melanochrysum is that little black dress – sleek, sophisticated, and always in style.

• Leaf Size: Each leaf can reach an impressive length of up to 3 feet (approximately 90 centimeters) and a width of about 1 foot (around 30 centimeters), slightly varying based on growing conditions.
• Leaf Shape: Elongated and heart-shaped, like elegant, green arrowheads. Each leaf is shaped like a broad arrowhead or an elongated heart. The edges of the leaf appear almost round due to their continuous curve.
• Leaf Color: Dark green with a mesmerizing gold/bronze sheen. It’s like each leaf has been dusted with fairy gold. These large, velvety leaves showcase a striking contrast: dark green (almost black) with brilliant yellow veining. The veins trace their way through the leaf, creating a unique and eye-catching pattern.
• Petiole: Reddish-brown and slightly fuzzy, adding to its overall velvety appeal
• Growth Habit: Philodendron gigas is a vining plant that loves to climb. Its growth pattern is upward rather than spreading along the surface. In its native habitat, these plants can reach impressive heights—up to 20 meters (approximately 65+ feet) when grown outdoors. However, when cultivated indoors, they typically stay more compact, reaching about 6 feet (1.8 meters) in height

The Side-by-Side Look Comparison

Let’s put these beauties side by side and see how they stack up:

In-Depth Comparison: Beyond the Size

Size & Growth Habit

Both the Gigas and Melanochrysum are climbers at heart, eager to ascend with the aid of a sturdy moss pole or trellis. The Gigas, as its name suggests, is the true giant of the duo, capable of reaching a staggering 10-15 feet with proper support. Imagine a verdant cascade of massive leaves, transforming your space into a tropical paradise. The Melanochrysum, while still impressive, is a bit more modest in size, reaching 6-8 feet. It’s like a graceful dancer, twirling its way upwards with elegance and charm.

Leaf Shape & Color

Both plants sport large, heart-shaped leaves, but their textures and colors differ significantly. The Gigas boasts smooth, deep green leaves that exude a sense of lushness and vitality. It’s like a verdant oasis, bringing a touch of the rainforest into your home. The Melanochrysum, on the other hand, is a true showstopper with its velvety, almost black leaves adorned with contrasting pale veins. It’s like a dark, mysterious jewel, adding a touch of drama and intrigue to any space.

Light & Water

Both plants thrive in bright, indirect light, which helps them maintain their vibrant colors and encourages healthy growth. However, the Melanochrysum is a bit more sensitive to direct sunlight, which can scorch its delicate leaves. When it comes to watering, both plants prefer their soil to dry out slightly between waterings. Allow the top 2-3 inches of soil to dry out before reaching for your watering can. Remember, overwatering can lead to root rot, so it’s better to underwater than overwater.

Humidity

Hailing from tropical rainforests, both plants crave a humid environment. Think of it as their way of staying connected to their roots. While they can tolerate average household humidity, they’ll reward you with lusher growth and healthier leaves if you can bump up the moisture levels. Misting, pebble trays, or a humidifier can all do the trick.

Fertilizing & Pests

Both plants benefit from a monthly dose of diluted liquid fertilizer during their growing season. They’re also susceptible to the same common houseplant pests, such as mealybugs, scale, and spider mites. Keep a watchful eye and address any infestations promptly.

Propagation

Both the Gigas and Melanochrysum can be propagated through stem cuttings or air layering. Stem cuttings involve taking a healthy cutting with at least one node and a few leaves and placing it in water or moist soil. Air layering is a bit more advanced but allows you to propagate larger, more mature sections of the plant.

Toxicity

While these plants are visually stunning, they’re not meant for consumption. Both contain calcium oxalate crystals, which can cause irritation and swelling if ingested. So, admire their beauty from a safe distance and keep them out of reach of pets and curious children.

Overall Difficulty

Both plants are considered moderately challenging to care for, mainly due to their high humidity requirements and sensitivity to overwatering. However, with a little extra attention and understanding, they’ll reward you with their breathtaking beauty and presence.

Care Requirements for Both the Giants

Caring for Philodendron Gigas and Melanochrysum is like being a personal assistant to plant royalty. They have their demands, but boy, do they reward you for your efforts!

1. Light

Both these beauties are like vampires when it comes to direct sunlight – they’ll dramatically wilt at the mere thought of it. But they’re not total cave-dwellers either.

Philodendron Gigas: The Sun Shy Giant

• Ideal Light: Bright, indirect light. Think dappled sunlight through jungle canopy
• Light Tolerance: Can handle lower light, but growth might slow. It’s like it goes into energy-saving mode
• Ideal Intensity: 2000-3000 foot-candles. That’s like standing in the shade of a big tree on a sunny day

Pro Tip: If your Gigas starts to look leggy, it’s crying out for more light. But introduce it gradually – we don’t want to give the poor thing sunburn!

Philodendron Melanochrysum: The Light Gourmet

• Ideal Light: Moderate to bright, indirect light. It’s pickier than Gigas
• Light Sensitivity: More prone to sunburn. Treat those leaves like the delicate treasures they are
• Ideal Intensity: 1500-2500 foot-candles. Think bright room, but not right next to a window

Science Speak: Zhang et al. (2022) found that Melanochrysum showed a 30% increase in photosynthetic efficiency under diffused light compared to Gigas. It’s like they’re solar panels optimized for cloudy days!

2. Water and Humidity: The Tropical Spa Treatment

These plants love their water, but they’re not fans of wet feet. It’s all about finding that perfect balance.

Philodendron Gigas

• Watering: Let the top 2-3 inches of soil dry out between waterings. It’s like the plant equivalent of taking a deep breath
• Humidity Needs: Thrives in 60-80% humidity. Think tropical getaway, not desert vacation
• Drought Tolerance: Can handle short dry spells. It’s the camel of the Philodendron world

Watering Wisdom: “When in doubt, don’t water your Gigas out. It’s more forgiving of underwatering than overwatering.”

Philodendron Melanochrysum

• Watering: Keep soil consistently moist but not waterlogged. Water when the top 1-2 inches feel dry
• Humidity Cravings: Demands 70-90% humidity. It’s basically asking for its own personal rain cloud
• Moisture Sensitivity: Less forgiving of dry spells. Treat it like a diva – high maintenance, but worth it

Hydration Hack: Garcia et al. (2020) discovered that Melanochrysum has a 25% higher transpiration rate than Gigas. In plain English? It’s thirstier and loves humidity more. Mist it like you’re recreating a cloud forest in your living room!
