Plants That Grow In Water Without Soil
If you love plants but hate potting mix, or you want a splash of green for a sunny windowsill, you’re in luck. Plenty of plants grow happily in water without soil — from classic houseplants rooted in vases to true aquatic species that live entirely submerged or floating. I’ve been keeping a mix of both on my kitchen counter and in a small tabletop aquarium for years, and I’ll share what grows best, how to care for them, and a few personal tips that make water-grown plants thrive.
Why grow plants in water?
Growing plants in water is clean, decorative, and often low-maintenance. No mess from potting soil, fewer pests, and you can easily watch roots develop. For beginners, rooting cuttings in water is an excellent way to expand your plant collection. For seasoned gardeners, water gardening opens possibilities for aquatic plants and simple hydroponic herbs.

Popular houseplants that grow well in water
These are the plants I recommend if you want attractive, hardy greenery that will live comfortably in a vase or bottle for months or longer.
- Pothos (Epipremnum aureum) — Legendary for water propagation and long-term growth. Tolerates low light and sends roots quickly.
- Philodendron (heartleaf and similar) — Very forgiving; beautiful trailing vines in a clear bottle.
- Spider plant (Chlorophytum comosum) — Plantlets root readily in water and make great gift jars.
- Lucky bamboo (Dracaena sanderiana) — Often sold in water; thrives with clean water and pebbles.
- Tradescantia/Wandering Jew — Fast grower with colorful stems; great in water but prefers brighter light.
- Basil, mint, chives — Many culinary herbs root well and can be grown in water for weeks while you harvest cut-and-come-again greens.
- Begonia leaf cuttings — Some begonias will produce roots and new plantlets from a leaf placed in water.
True aquatic plants that need no soil
These plants live naturally in water ecosystems and are ideal for aquariums, ponds, and water bowls where they float or attach to decor:
- Anacharis/Elodea — A submerged oxygenator that grows quickly and is easy to propagate.
- Hornwort (Ceratophyllum demersum) — Floats or stays submerged and helps keep water clean.
- Java fern (Microsorum pteropus) — Does not need substrate; tie to driftwood or rock to anchor.
- Java moss — Perfect for aquariums; carpets driftwood and hides tiny aquatic friends.
- Water lettuce and water hyacinth — Free-floating surface plants that give a lush look to ponds and large containers.
- Duckweed — Tiny floating plants that spread quickly and provide shade in aquariums and ponds.
How to grow and care for plants in water
Growing plants in water is easy when you focus on a few basics: water quality, light, nutrients, and cleanliness. Here are the simple steps I use every time I start a new water garden.
- Select healthy cuttings — Choose a 4–6 inch cutting with at least one node (a little bump on the stem). That’s where roots form.
- Use clean containers — Glass jars, clear vases, or a small aquarium let you watch roots and look fabulous on a shelf.
- Choose the right water — Tap water is fine in most places; if your water is heavily chlorinated, let it sit 24 hours or use filtered water.
- Change water regularly — Replace half the water every 1–2 weeks to prevent stagnation and nutrient depletion.
- Add light — Bright, indirect light is ideal for most houseplants. True aquatic plants may need moderate to high light depending on species.
- Provide nutrients — Plants in water need feeding. Use a diluted liquid fertilizer for houseplants or an aquarium plant fertilizer for submerged species.
- Prevent algae — Keep direct sunlight off your jars, clean containers occasionally, and change water frequently.
Troubleshooting common problems
Even water plants have issues. Here’s how I handle the usual suspects:
- Yellowing leaves — Often a sign of nutrient deficiency; feed with a half-strength liquid fertilizer.
- Brown rotting roots — Stagnant or dirty water causes rot; trim damaged roots, refresh water, and increase oxygen (an air pump helps in larger setups).
- Algae growth — Move the jar away from intense sun, perform more frequent water changes, and clean the glass.
- Slow growth — Boost nutrient supply slightly and check light levels; some plants need brighter light to thrive in water.
My favorite setups and tips
I keep a few jars of pothos and philodendron on my windowsill and a small planted tank with Java fern and moss on my desk. Here are my personal tricks:
- Use pebbles or marbles to anchor stems in decorative jars — it looks tidy and keeps cuttings upright.
- Add a small bit of activated charcoal under the pebbles — it helps keep water clear and reduces odors.
- Label jars with the start date — it’s fun to see how long roots take and which cuttings do best.
- Rotate cuttings — I move plants around the house seasonally so they get the right light and don’t stretch awkwardly.
Final thoughts
Plants that grow in water without soil are a delightful way to bring greenery into any space. They’re forgiving, decorative, and a great introduction to propagation and hydroponics. Whether you want a floating pond-like vibe with water lettuce, a practical herb station of basil and mint, or long trailing pothos in glass, water gardening offers endless possibilities. Try a few cuttings and enjoy the surprisingly therapeutic process of watching roots unfurl and new growth emerge.
Happy gardening — and if you try a new water-grown plant, I’d love to hear which one surprised you the most.
