What plants can actually live in water long-term in Canada?

Only a few houseplants genuinely thrive indefinitely with their roots in water: lucky bamboo (Dracaena sanderiana), which is what Pinterest listicles are really promising, and pothos with the help of a weak liquid fertiliser. A handful of other plants — philodendron, English ivy, spider plant, Chinese evergreen, wandering jew, coleus — can live in water for months to years with regular fertilising and water changes, but they grow slower and produce smaller leaves than the same plant in soil. Many other plants you'll see on social-media lists — peace lily, African violet, basil, mint, sweet potato vine — really only root in water for propagation and decline if you try to keep them there permanently.

Can a pothos really live in water forever?

Pothos is one of the few houseplants that can genuinely live in water indefinitely, and many Canadian growers keep one in a vase for years. The catch is nutrients: water alone provides almost none, so a water-grown pothos needs a weak liquid houseplant fertiliser added every few weeks. Without it, the leaves slowly shrink, yellow, and the plant declines. The plant in water also grows noticeably slower and produces smaller leaves than the same cutting potted in soil. So yes, pothos lives in water — but a fertilised, well-tended water-grown pothos is the realistic version, not the perfectly-clear-vase Pinterest version.

Do I need fertilizer for plants growing in water in Canada?

Yes, for anything you want to keep alive beyond a couple of months. Tap water provides essentially no nutrients; the cutting depletes its reserves in weeks. Use a balanced liquid houseplant fertiliser at one-quarter to one-half the label-recommended strength, added to the vase every 2–4 weeks. Skip fertiliser only for true short-term propagation — once a cutting has rooted and you plan to keep it in water, start feeding. Canadian municipal water with chlorine or fluoride is fine for most water-grown plants but can damage fluoride-sensitive species like spider plants, dracaenas, and calatheas; use filtered or rainwater for those, or let tap water sit out 24 hours.

How often should I change the water for water-grown plants?

Refresh the water completely every 1–2 weeks. Over time the water clouds, depletes its small dissolved oxygen, accumulates root exudates and any added fertiliser salts, and starts to host algae and bacteria — all of which slow the plant down. A quick rinse of the roots under tap water at each change keeps things healthy. Top up between changes if evaporation lowers the level. Use room-temperature water; cold water shocks tropical roots.

Can I move a houseplant from soil into water?

Yes, but with mixed success. Plants started from cuttings in water grow water-specific roots that suit the medium; plants moved from soil already have soil-roots that often rot when submerged. The reliable method is to take a cutting from your soil-grown plant and root the cutting in water, rather than uprooting the whole plant. The exceptions are the easiest water-growers — pothos, philodendron, and English ivy will sometimes adapt directly from soil to water, especially young plants — but expect some lost leaves while the plant rebuilds its root system.

Why is my water-grown plant slowly dying or turning yellow?

The two most common causes are nutrient starvation and stagnant water. Add a weak liquid fertiliser every 2–4 weeks and refresh the water completely every 1–2 weeks. Other causes: too little light (water-grown plants still need the same bright indirect light as soil-grown), tap-water sensitivity (use filtered water for fluoride-sensitive species), a vessel that traps too much heat or too little oxygen, or simply trying to keep a plant in water that really wants soil — peace lilies, African violets, and most herbs will eventually decline in water no matter what you do.

HOUSEPLANT ROUNDUP

Plants That Grow in Water — An Honest Guide for Canada

Which houseplants actually live in water long-term, which can live there with nutrients, and which only root in water and need soil to thrive — sorted into three honest tiers so you know what you're really signing up for.

The honest summary: The only plants that truly thrive in water indefinitely are lucky bamboo and pothos (with a weak liquid fertiliser added every few weeks). Philodendron, English ivy, spider plant, Chinese evergreen, wandering jew, and coleus can live in water for months or years with regular feeding and water changes, but grow slower than in soil. Peace lily, African violet, begonia, mint, basil, sweet potato vine root in water but really want soil — treat them as propagation, not a permanent home.

The Honest Truth About Plants in Water

Search "plants that grow in water" and you'll find pretty Pinterest grids of 15 or 20 plants in clear vases. The grids aren't wrong, exactly — every plant on them can live in water for a while — but they leave out the important part: most of those plants only root in water for propagation, and decline if you try to keep them there. A small handful actually live in water long-term.

Tier 1 plants below truly thrive in water for years. Tier 2 plants survive there for many months — even years — if you keep up with feeding and water changes, though they always do better in soil. Tier 3 plants are for water propagation only: pot them up in soil within a few weeks once they have roots.

Tier 1 — Truly Thrives in Water Long-Term

Two plants are genuinely happy living in water indefinitely. Both still need a weak liquid fertiliser every few weeks — tap water provides no nutrients.

Lucky Bamboo (Dracaena sanderiana)

The plant most famously grown in water — sold as bundled stalks in glass dishes of pebbles and water for exactly this purpose. Native to tropical Africa, despite the name; not actually a bamboo. Use filtered or rainwater (lucky bamboo is sensitive to the fluoride in tap water), keep the water level just covering the lower roots, and add a drop or two of liquid houseplant fertiliser every 2–4 weeks. Place in bright indirect light; direct sun yellows the leaves. Toxic to cats and dogs, like all dracaenas.

Pothos (Epipremnum aureum)

A pothos cutting placed in a vase of water roots within weeks and can keep growing indefinitely. With a weak liquid fertiliser added every 2–4 weeks, water-grown pothos lives for years — Canadian growers commonly keep one in a tall vase in a kitchen window for half a decade. Without fertiliser the leaves slowly shrink and yellow. Water-grown pothos always grows slower and stays smaller-leaved than the same plant in soil. Toxic to pets. Full pothos care →

Tier 2 — Survives in Water for Months or Years (With Care)

These plants will live in water for a long stretch as decorative pieces, but they will always grow more slowly than in soil and you have to stay on top of feeding and clean water. Treat them as water plants with an asterisk.

Heartleaf Philodendron (Philodendron hederaceum)

Almost as easy as pothos in water — cuttings root readily and the plant can stay in a vase for years with a weak liquid fertiliser. Grows slower and smaller than in soil. Toxic to pets. Full philodendron care →

English Ivy (Hedera helix)

English ivy cuttings root in water within weeks and tolerate long-term water culture better than most leafy plants. Likes cooler rooms, like a kitchen sink or bright bathroom window. Watch the water clarity — ivy is prone to algae in warm conditions. Toxic to pets. Full English ivy care →

Spider Plant (Chlorophytum comosum)

Spider-plant babies root in water in days and a whole rooted baby can live in a small vase for many months. Use filtered or sat-out water — spider plants are mildly fluoride-sensitive, which shows as brown leaf tips in water-grown plants on tap water. Pet-safe. Full spider plant care →

Chinese Evergreen (Aglaonema)

Aglaonema cuttings root well in water and can stay there for many months. The plain green varieties cope best; colourful pink hybrids decline faster in water culture. Toxic to pets. Full Chinese evergreen care →

Wandering Jew / Tradescantia (Tradescantia zebrina)

One of the fastest plants to root in water — a cutting in a glass jar develops a knot of roots in under two weeks. Lives in water for several months happily, then needs potting or it gets leggy and faded. The purple-and-silver striped foliage looks beautiful in a clear vase. Tradescantia spp. are mildly toxic to pets.

Coleus (Plectranthus scutellarioides)

A cutting from a Canadian summer-bed coleus roots in water in a week and can live indoors in a vase through the winter as a way to overwinter the colour — many Canadian gardeners use water-rooting to keep their favourite coleus alive between outdoor seasons. The cutting will eventually want potting, but a winter in water is realistic.

Tier 3 — Root in Water, But Need Soil to Thrive

These are the plants that fool Pinterest into thinking everything grows in water. They root readily in a glass on a windowsill — which is genuinely useful for propagation — but pot them up within a few weeks once roots are 5–8 cm long. Left in water they slowly decline.

Peace Lily (Spathiphyllum)

Often sold sitting in a glass vase with a betta fish — a charming arrangement that doesn't actually work for the plant. A peace lily in water survives but stops flowering, slowly shrinks, and eventually fails after a year or two. Pot the divisions in soil for a happy plant. Full peace lily care →

African Violet (Saintpaulia)

A leaf cutting in water roots reliably and is the standard way to propagate African violets — once you have a small plantlet, pot it up in African violet mix. They will not flower or live long-term in water.

Begonia (Begonia spp.)

Begonia stem cuttings and even leaf cuttings root in water — another reliable propagation route. Pot up the rooted plantlets in a peaty, well-draining mix. They will not bloom or thrive in water.

Mint, Basil, and most kitchen herbs

Herbs root in water within a week — a useful, free way to multiply a grocery-store bunch into a windowsill garden. Pot the rooted cuttings within 2–3 weeks. Left in water, herbs go pale, weak, and inedible within a month or two; they really need soil and bright light to produce the flavour you grew them for.

Sweet Potato Vine (Ipomoea batatas)

A sweet potato suspended over a glass of water sprouts striking trailing vines — a fun kitchen project, especially with kids. The vines look great for a few months but the plant is really running on the tuber's reserves; for a long-lived plant, eventually pot it up in soil.

Snake Plant — the common Pinterest myth

Snake plant turns up on most "grow in water" lists, but the truth is awkward: snake plant cuttings rot in water more often than they root, and even a successfully water-rooted snake plant lives a precarious life and ultimately needs soil. If you want to propagate one, division of the rhizome or careful soil propagation works far better. Don't try to keep a snake plant in water long-term. Full snake plant care →

How to Grow a Plant in Water — the Practical Setup

The vessel

A clear glass jar, vase, or bottle that lets you watch the roots is most popular — though clear glass also encourages algae in bright light. A narrow neck supports a cutting upright. For decorative arrangements, propagation stations with multiple test-tube vials look good and let you grow several plants together.

The water

Room-temperature water is essential — cold tap water shocks tropical roots. For most plants, regular Canadian tap water is fine if you let it sit out 24 hours so chlorine can dissipate. For lucky bamboo, spider plant, dracaena, and calathea (all fluoride-sensitive), use filtered or rainwater. Refresh the water completely every 1–2 weeks — a quick root-rinse at the same time keeps things healthy.

Feeding (this is the part Pinterest skips)

Water alone has almost no nutrients. Any plant you intend to keep in water more than a couple of months needs a weak liquid houseplant fertiliser at one-quarter to one-half label strength, added every 2–4 weeks. Without it, leaves slowly shrink and yellow. This single step is what separates a thriving water-grown plant from a slowly declining one.

Light

A water-grown plant has the same light needs as the soil-grown version. Bright indirect light suits most picks here — an east window is ideal in a Canadian home. Avoid direct sun on a clear glass vessel: it cooks the roots and accelerates algae. Through the dark winter months, move the vessel to your brightest window or add a small grow light.

Common Questions about Plants in Water

Can I move a soil-grown plant straight into water?

Sometimes, with caveats. Plants started from cuttings in water grow water-specific roots that suit the medium; plants moved from soil have soil-roots that often rot when submerged. The reliable approach is to take a cutting from your soil plant and root the cutting in water instead. Young pothos, philodendron, and English ivy will sometimes adapt directly from soil to water; mature plants of those species and most others usually struggle.

Why does my water-grown plant get cloudy water and algae?

Clear glass vessels in bright light grow algae — that's chemistry, not failure. Refresh the water every 1–2 weeks and rinse the roots, move the vessel out of direct sun, and consider an opaque or coloured vessel if algae keeps coming back. Cloudy water that smells off is bacterial buildup — same fix: change the water more often.

Can I grow vegetables hydroponically at home in Canada?

Yes — but proper hydroponics is different from sticking a basil cutting in a glass. Real hydroponics uses a balanced nutrient solution, air or root oxygenation, and pH monitoring. Compact countertop hydroponic systems (Aerogarden and similar) work well for lettuce, herbs, and even some tomatoes through a Canadian winter. If your interest in “plants in water” is really about food, a small hydroponic kit will outperform any windowsill jar.

What's the easiest plant to start with in water?

A pothos cutting. Cut a length of vine with a few leaves, place it in a glass of room-temperature water on a bright shelf, and refresh the water weekly. Roots appear within 2–3 weeks, and the cutting lives in the vase indefinitely. Once it has rooted, start adding a weak liquid fertiliser every few weeks. Lucky bamboo is the next-easiest — it's specifically sold for water culture — though it needs filtered water.

Set Up a Propagation Station — Step by Step

A “propagation station” is just an organised row of cuttings rooting in water. Done well, it doubles as a living shelf-piece and is the fastest way to grow your collection for free. Here is the order of operations that gives the best success in a Canadian home.

Pick the right cutting. 4–6 inches of healthy stem with at least two leaf nodes (the bumps where leaves attach). Roots emerge from nodes, not the stem itself. For pothos and philodendron, cut just below a node. For monstera, include at least one aerial root if you can.
Strip the lower leaves. Submerged leaves rot and turn the water cloudy. Leave 2–3 leaves at the top; remove anything that would sit below the waterline.
Choose your vessel. Tall glass bottles, test tubes, or repurposed jam jars all work. Glass lets you watch the roots; opaque ceramic slows algae. The neck of the vessel should hold the cutting upright without bunching the leaves into the water.
Use room-temperature water. Tap water is fine for most plants — let it sit overnight to off-gas chlorine if your municipality treats heavily. Avoid softened water (high sodium). Filtered or rainwater is best for sensitive picks like lucky bamboo and spider plant.
Place the station in bright indirect light. An east-facing windowsill is ideal in a Canadian home. South-facing works if a sheer curtain diffuses direct sun — otherwise the glass heats up and cooks the roots. Don't put it next to a radiator.
Refresh weekly. Tip the old water down the drain (or onto a soil plant — it's a weak liquid fertiliser by week two), rinse the roots gently, and refill. Don't “top up” — replace.
Start feeding once roots are 5–7 cm long. Add a single drop of balanced liquid houseplant fertiliser per litre when you refresh the water. Plants in water cannot scavenge nutrients from soil and will stall without this step.
Decide: stay in water or pot up. Many gardeners pot rooted cuttings into soil at this stage. Plants that thrive long-term in water (pothos, philodendron, lucky bamboo, English ivy) can stay in their vessel indefinitely with weekly water changes and a drop of fertiliser. Others (monstera, ZZ, dracaena) only do well in water for a few months — pot them up before they decline.

The most common failure point is forgetting to change the water. After 3–4 weeks of neglect, the water turns yellow, the roots blacken, and the cutting collapses. Set a phone reminder — same day every week — and your propagation station will run itself.
