Dark, moody houseplants have taken over Pinterest and Instagram feeds and it’s easy to see why. Deep black, near-black, and inky purple foliage adds a dramatic, sophisticated touch that plain green plants simply can’t match. What makes these plants even more appealing is that many of them can be grown or propagated directly in water, making them incredibly easy to care for, display, and multiply.
Growing plants in water isn’t just convenient it’s also a great way to watch root development, avoid messy soil, and create a sleek, modern display on a windowsill or shelf. In this guide, we’ll walk through seven striking black houseplants that thrive in water, along with tips on how to grow and care for each one.
Why Grow Houseplants in Water?
Before we dive into the list, here’s why water-grown houseplants have become so popular:
- Low mess – No soil, no spills, easy to maintain
- Easy to monitor root health – You can see exactly what’s happening below the surface
- Great for propagation – Many plants root faster in water than in soil
- Aesthetic appeal – Glass vases and jars create a clean, minimalist look
- Beginner-friendly – Ideal for those who tend to overwater or underwater soil-grown plants
Now, let’s look at seven black houseplants that fit perfectly into a water-growing setup.
1. Raven ZZ Plant (Zamioculcas zamiifolia ‘Raven’)
The Raven ZZ Plant is one of the most sought-after black houseplants today. Its leaves emerge lime green and darken into a deep, glossy black-purple over time, creating a striking contrast against most home decor.
Growing in water:
- Take a healthy leaf or stem cutting and place it in a jar of water
- Keep in bright, indirect light
- Roots typically develop within several weeks, though ZZ plants are slow growers
- Change the water every 1–2 weeks to prevent stagnation
Why it’s great: Like all ZZ plants, the Raven variety is extremely drought-tolerant and low-maintenance, making it extremely forgiving for beginners.
2. Philodendron ‘Black Cardinal’
Philodendron Black Cardinal starts out with deep burgundy-red leaves that mature into a rich, near-black color. Its glossy, heart-shaped foliage makes it a standout addition to any indoor jungle.
Growing in water:
- Cut a stem section with at least one node
- Submerge the node in water, keeping leaves above the waterline
- Place in bright, indirect light
- Roots usually appear within 2–4 weeks
Why it’s great: Philodendrons are among the easiest plants to propagate and grow long-term in water, making Black Cardinal a great low-fuss statement plant.
3. Black Pothos (Epipremnum Dark Varieties)
Darker pothos varieties, often sold as “Black Pothos” or deep-toned Epipremnum cultivars, feature nearly black, glossy leaves that trail beautifully from shelves or hanging planters.
Growing in water:
- Snip a vine section just below a node
- Place in a water-filled vase or jar
- Position in medium to bright indirect light
- Roots typically form within 1–3 weeks, and pothos can live in water indefinitely
Why it’s great: Pothos is famously one of the easiest houseplants to grow, and it thrives in water long-term with minimal care — perfect for beginners.
4. Colocasia ‘Black Magic’ (Black Elephant Ear)
For a bold, dramatic look, Colocasia ‘Black Magic’ delivers with its enormous, velvety black-purple heart-shaped leaves. As a naturally moisture-loving plant, it’s especially well-suited to water culture.
Growing in water:
- Best propagated by dividing tubers with roots attached, then placing roots in water
- Keep in bright, indirect to partial direct light
- Because Colocasia naturally grows in wet, boggy conditions, it tolerates sitting in water far better than most houseplants
Why it’s great: Its striking size and color make it an instant focal point, and its natural love of water makes it one of the easiest plants on this list to grow hydroponically.
5. Alocasia ‘Black Velvet’ (Alocasia reginula)
Known for its velvety, near-black leaves with silvery veins, Alocasia Black Velvet is a compact, jewel-like plant that has become a favorite among collectors.
Growing in water:
- Propagate by dividing offshoots/pups with a few roots attached
- Place roots in water, keeping the corm above the waterline to prevent rot
- Provide bright, indirect light and warm, humid conditions
Why it’s great: While Alocasias can be a bit more finicky than pothos or philodendron, the payoff is a stunning, textured, jewel-toned plant that stands out in any collection.
6. Purple Heart (Tradescantia pallida)
Though technically a deep violet-purple, Purple Heart often reads as near-black in lower light, especially with its rich, saturated coloring. It’s a fast, easy grower that adapts extremely well to water.
Growing in water:
- Cut stem sections just below a leaf node
- Place directly in water in bright light
- Roots typically appear within just 1–2 weeks
- Can be grown in water indefinitely as a trailing accent plant
Why it’s great: Purple Heart is one of the fastest and easiest plants to propagate in water, making it ideal for beginners who want quick, visible results.
7. Cordyline ‘Black Mystique’
Cordyline ‘Black Mystique’ features long, strappy, near-black leaves that add a bold, architectural element to any space. It’s a striking alternative to typical green foliage plants.
Growing in water:
- Take a cutting with a portion of stem
- Place in water in bright, indirect light
- Roots may take several weeks to develop, as Cordyline is a slower propagator
- Once well-rooted, it can be transitioned to soil or kept in water with regular changes
Why it’s great: Its bold, spiky silhouette adds contrast and drama, especially when paired with softer, trailing plants like pothos or Purple Heart.
Tips for Success When Growing Black Houseplants in Water
- Use clean, filtered water when possible — chlorine and fluoride can affect sensitive roots over time
- Change the water every 1–2 weeks to prevent bacterial buildup and odor
- Place in bright, indirect light — dark-leafed plants often need slightly more light than green varieties to maintain their deep coloring
- Use glass containers to monitor root health and add a clean, decorative touch
- Add a pinch of liquid fertilizer occasionally if keeping plants in water long-term, since water alone lacks the nutrients found in soil
Conclusion
Black houseplants bring a bold, sophisticated edge to indoor spaces, and growing them in water makes them even more accessible and low-maintenance. From the glossy Raven ZZ Plant to the dramatic Colocasia ‘Black Magic,’ these seven dark beauties prove that striking color and easy care can absolutely go hand in hand. Whether you’re propagating cuttings for new plants or building a full water-garden display, these moody favorites are sure to make a statement in any room.
