A calla lily can grow in water, but not the way you might think.
Yes, you can grow a calla lily in water, but it’s not like growing a peace lily in a vase where the roots just sit in a jar of tap water.
When we talk about whether a calla lily can grow in water, we’re mostly talking about starting rhizomes or rooting cut stems, not keeping the plant fully submerged forever.
The truth is, calla lilies love moisture, and they can absolutely be started in water, but they’ll need a transition to well-draining soil if you want them to thrive long-term.
In this post, we’ll dig into how a calla lily can grow in water, what conditions make it work, and why you might want to try it or skip it.
Let’s get those roots wet and explore this fun way to garden.
Why a Calla Lily Can Grow in Water
A calla lily can grow in water because these plants are naturally semi-aquatic in their native habitats.
In the wild, calla lilies often grow along stream banks, pond edges, and marshy areas where the soil stays consistently damp or even waterlogged.
So the idea of growing a calla lily in water isn’t far-fetched at all—it’s actually rooted in their natural preferences.
Here’s what makes water propagation work for calla lilies.
1. Calla Lily Rhizomes Can Sprout in Water
If you have calla lily rhizomes (those bulb-like structures), you can absolutely place them in water to kickstart growth.
Set the rhizome in a shallow dish or glass jar with just enough water to cover the bottom third.
Keep the top of the rhizome above the water line so it doesn’t rot.
Within a week or two, you’ll see roots shooting down into the water and tiny green sprouts emerging from the top.
This is one of the easiest ways to prove that a calla lily can grow in water, at least in the early stages.
2. Calla Lily Cuttings Root in Water Too
If you’re wondering whether a calla lily can grow in water starting from a stem cutting, the answer is also yes.
Take a healthy stem with a node, place it in a glass of clean water, and wait.
Roots will develop from the node after a few weeks, just like with many other houseplants.
This method is great for multiplying your calla lilies without disturbing the main plant.
Just change the water every couple of days to keep it fresh and oxygenated.
3. Calla Lilies Thrive in Wet Conditions
Another reason a calla lily can grow in water is that they don’t mind having their feet wet, especially during the growing season.
Unlike many plants that suffer from overwatering, calla lilies appreciate consistent moisture.
This makes them perfect candidates for water-based growing methods, at least temporarily.
They also love humidity, so being near water or in a water-filled container mimics their natural environment.
So if you’ve been hesitant, know that a calla lily can grow in water with the right approach.
How to Grow a Calla Lily in Water Successfully
Now that you know a calla lily can grow in water, let’s talk about how to do it properly.
If you just toss a rhizome into a bucket of water, you’ll end up with a mushy mess.
But with the right setup, you can have a calla lily grow in water beautifully.
Here are the steps you need to follow.
1. Start With Clean Water and a Wide Container
Use filtered or distilled water if possible, as chlorine in tap water can stress young roots.
Choose a wide, shallow container like a mason jar, glass bowl, or even a small vase.
The opening should be wide enough to support the rhizome without letting it fall completely into the water.
A calla lily can grow in water best when only the bottom half of the rhizome is submerged.
2. Place Pebbles or Stones for Support
Add a layer of clean pebbles, glass beads, or marbles to the bottom of your container.
Nestle the calla lily rhizome among the pebbles so it stays upright.
Then add water until it reaches just below the top of the pebbles.
This keeps the rhizome moist but not drowning, which is the sweet spot for growth.
3. Provide Bright, Indirect Light
Calla lilies love bright light, but direct sun can cook the roots when they’re in water.
Place your container near a sunny window but with a sheer curtain filtering the light.
A spot that gets morning sun and afternoon shade works perfectly.
Remember, a calla lily can grow in water, but it still needs light for photosynthesis.
4. Change the Water Weekly
Stagnant water is a breeding ground for bacteria and algae, which can kill your calla lily.
Every seven days, dump out the old water and rinse the pebbles and roots gently.
Refill with fresh, clean water to the same level.
This simple maintenance keeps your calla lily growing in water healthy and happy.
5. Move to Soil Once Roots Are Established
While a calla lily can grow in water for a few months, it’s not a permanent solution.
Once the roots are several inches long and you see healthy foliage, it’s time to transition to potting soil.
Fill a pot with well-draining soil, make a hole, and gently place the rooted rhizome in.
Water thoroughly and keep the soil consistently moist for the first few weeks.
This transition gives your calla lily the nutrients it needs to produce those stunning blooms.
Common Mistakes When Growing a Calla Lily in Water
Even though a calla lily can grow in water, there are some pitfalls you’ll want to avoid.
Here’s what typically goes wrong and how to fix it.
1. Submerging the Entire Rhizome
If you completely submerge the rhizome, you’ll invite rot and fungal growth.
Always keep the top third above the waterline.
A calla lily can grow in water only if the rhizome can breathe.
2. Using Dirty or Cold Water
Cold water shocks the roots, and dirty water breeds disease.
Use room-temperature water and refresh it regularly.
Your calla lily will grow in water much faster when the conditions are warm and clean.
3. Skipping the Soil Transition
Leaving a calla lily in water too long will lead to nutrient deficiencies.
Water alone doesn’t provide the minerals and organic matter the plant needs to flower.
So while a calla lily can grow in water initially, it won’t bloom without soil eventually.
So, Can a Calla Lily Grow in Water?
A calla lily can grow in water, but only as a temporary propagation method.
It’s fantastic for rooting new rhizomes or cuttings, and it’s a fun project for kids or curious gardeners.
But for a thriving, flowering calla lily, you’ll need to move it into soil once the roots establish.
We hope this guide has answered your question about whether a calla lily can grow in water and given you the confidence to try it yourself.
Try it out, watch those roots sprout, and enjoy the magic of watching a calla lily grow in water right before your eyes.
