Growing plants in water offers a quiet satisfaction. It brings back the curiosity of childhood science experiments while offering a clean, low-maintenance way to enjoy greenery indoors. With just a clear glass, fresh water, and a sunny windowsill, many plants can take root and even thrive long-term. These plants that grow in water are ideal for small spaces, minimal upkeep, and anyone who wants to enjoy plant care without dealing with potting soil.
This guide explores some of the most rewarding plants to grow hydroponically at home. Each plant listed can root and continue to develop in water with proper care, natural light, and periodic water changes.
Why Grow Plants in Water?
Growing plants in water is appealing for several reasons. It is tidy, visually calming, and easier to monitor. With roots exposed behind clear glass, you can observe growth as it happens. This method also reduces risks of soil pests and minimizes mess in kitchens, offices, or living rooms.
Benefits of Water Propagation
- Low maintenance compared to soil-based care.
- Visually appealing root systems and clean presentation.
- Reduced risk of soil fungus, gnats, and overwatering issues.
- Ideal for small indoor environments, desktops, and bathroom shelves.
- Encourages learning and appreciation for plant biology.
Best Plants That Grow in Water Indoor
1. Peace Lily (Spathiphyllum)
A peace lily adapts well to water when its roots are carefully cleaned and transitioned from soil. The plant’s glossy leaves and air-purifying properties make it a calming presence indoors. Keep the roots submerged, ensuring that the base of the crown remains above water to avoid rot. Bright, indirect light helps maintain leaf color and occasional flowers.
2. Hyacinth (Hyacinthus orientalis)
Hyacinths are often forced to bloom indoors during the cooler months. When placed in a forcing vase, the bulb stays above the water while the roots grow downward. With adequate light and cool temperatures, they produce fragrant blooms. After flowering, bulbs can sometimes be dried and replanted outdoors for future seasons.
3. Lucky Bamboo (Dracaena sanderiana)
Despite its name, lucky bamboo is not a true bamboo, but a member of the Dracaena genus. It grows quickly in clean water and prefers filtered or distilled water to prevent leaf tips from browning. It is often associated with positive energy in home decor and can be shaped or arranged to form artistic spirals or towers.
4. Lotus (Nelumbo nucifera)
The lotus is a classical aquatic plant known for its symbolic meaning and elegant blooms. When started from seeds or tubers, the lotus can thrive in a basin, bowl, or pond. Though it requires warmth and adequate sunlight, the plant’s roots remain fully submerged, forming a serene centerpiece in indoor water gardens or outdoor water features.
5. Amaryllis (Hippeastrum)
Amaryllis bulbs are striking when forced in water, producing tall stems topped with dramatic red or pink flowers. Place the bulb above water so that only the roots remain submerged. A bright location is necessary for strong, upright growth. After flowering, the bulb can be transferred to soil or discarded depending on preference.
6. Paperwhite Narcissus (Narcissus papyraceus)
One of the easiest plants to grow in water during winter, paperwhites bloom quickly and require little more than bright light. The bulbs can be placed on a bed of pebbles in a shallow container, with water touching only the base. Within a few weeks, clusters of white flowers appear, adding fragrance and brightness indoors.
7. Tradescantia (Tradescantia zebrina and related varieties)
Tradescantia, known for its trailing growth and colorful foliage, roots rapidly in water. Simply cut a healthy stem below a node and place it in a glass of clean water. The plant spreads easily, making it excellent for sharing cuttings or creating cascading displays. Refresh water often to prevent cloudiness and maintain healthy roots.
8. Water Hyacinth (Eichhornia crassipes)
Water hyacinth is a floating aquatic plant that thrives in ponds, fountains, or large bowls with adequate sunlight. It produces distinctive lavender flowers and forms clumping mats on the water’s surface. Because it grows quickly, it may need regular thinning. It is best suited for outdoor water features where space allows.
How to Care for Plants Growing in Water
To maintain healthy plants in water, consistency is key.
General Care Tips
- Use clean, chlorine-free water for healthier root development.
- Change the water weekly to prevent stagnation and bacterial buildup.
- Provide bright, indirect light to support growth and leaf coloration.
- Rinse roots occasionally to remove algae or mineral buildup.
- Add a hydroponic-safe liquid fertilizer once a month in very small amounts.
Frequently Asked Questions
Can plants grow forever in water?
Some species, such as lucky bamboo and tradescantia, can live indefinitely in water with proper care. Others may eventually benefit from being transferred to soil for long-term vigor.
Do water-grown plants need fertilizer?
Yes. Because water does not contain nutrients, a diluted hydroponic fertilizer helps maintain plant health over time.
What type of container is best?
Clear glass makes it easy to observe root growth, but tinted glass can reduce algae. Choose vessels that are stable, clean, and deep enough to support root systems.
Can tap water be used?
Tap water is fine in many regions, but if the water is heavily chlorinated, let it sit out overnight before use or switch to distilled water.
How do I prevent algae in glass jars?
Reducing direct sunlight on the jar and refreshing water regularly helps prevent algae growth.
