Did you know that there are many houseplants and herbs that you can grow in water only? This is known as hydroculture and is an easy way to have an indoor garden without the hassle of messing with potting mixes and remembering to water your plants. In fact, plants grown in water require very little maintenance and have very few pests and disease problems.
You can use almost any waterproof container to grow your plants in, but glass is usually best because you can see the roots as well. Actually, this method has been used by experienced gardeners the world over to propagate new plants quickly and easily.
Here are 33 plants that you can easily grow in water.
1. African Violet
You can grow African violets in water from just the leaves of an existing plant. Just cut off a few leaves from the mother plant, making sure that there are about 2 inches of stem on the leaf. Place these leaves in a lovely small glass vase or jar and make sure that only the stems are in the water.
It will take about a month for roots to start forming, and eventually, a small plantlet will form.
2. Arrowhead Plant (Syngonium podophyllum)
The arrowhead plant is easy to grow in water, and the large leaves make it quite an attractive addition to your indoor “garden.” Use stem cuttings and place these into an attractive jar filled with clean water. Refresh the water once or twice a week to keep your plant growing strong.
3. Baby’s Tears
Baby’s tears are surprisingly easy to grow in water. All you need to do is cut off a cluster of stems and put these in a small jar or vase of water. Make sure that you strip off the leaves that are on the parts of the stem that is going to be submerged. Otherwise, these leaves will rot if left sitting in the water.
It’s also a good idea to change the water frequently to remove any leaves that may be floating in the water.
Basil is one of those useful herbs that we can never have enough of. Especially in the cooler months when it won’t grow outside. The solution is to grow basil in water in your kitchen or other warm, bright spot in your home.

Lavender is a popular herb that many people love to grow. It’s even easier to grow lavender in water than in the soil as long as you give the plant plenty of bright light and add a couple of drops of liquid fertilizer to the water around once a month during the active growing season.
One of the best places to put your lavender is on a bright windowsill. If you have a bright spot in the bedroom, you’ll find that the lavender will help you sleep better as this herb is well known for its calming properties.
To grow lavender in water, take a few stem cuttings from a mature plant. Try to choose young stems that haven’t flowered yet. If you only have stems with flowers on them, then cut off the flower before placing the stem in water. If you don’t do this, the lavender stem will put all its energy into producing the flower and won’t produce any roots.
Before placing your stems in water, remove all the leaves from the bottom third or so of the stem. You don’t want to have any of the leaves sitting in the water because they’ll rot.
Choose a pretty glass bottle to grow your lavender in and try to use distilled or filtered water. Place the stems in the water, and make sure you position your plants where they can get plenty of morning sun. Roots should start to form within a few weeks.
Change the water often and add a few drops of liquid fertilizer every four weeks or so.

24. Lucky Bamboo (Dracaena sanderiana)
This is one of the easiest indoor plants to grow in water. Choose a narrow vase or jar and fill the bottom with some gravel or decorative stones. This helps to anchor the stems and keeps the plant in place.
Growing mint in water is a clever way to ensure that you always have enough on hand when you need it. All you have to do is take some stem cuttings from an established plant and strip the leaves from the bottom half.

28. Peace Lily
Who doesn’t love the gorgeous dark green foliage and the crisp white flowers of a peace lily? However, these plants have a massive root system, so if you’re growing one in a pot, it will need repotting every year. Here’s how to easily grow this plant in water instead next time it needs repotting.
- Take the plant out of the pot and remove all the soil from the roots by washing them in lukewarm water.
- With a sharp knife, remove the offshoots from the main plant. Ensure each offshoot has about four leaves growing from it.
- Pop these into a clear jar or vase filled with water. To keep the plants nice and healthy, remember to change the water at least once a week. Add a drop or two of liquid fertilizer around once a month.
Philodendrons, in general, are easy to grow but for growing in water, choose the heart-leaf philodendron as it will do best. To grow your philodendron, choose a clear glass jar or bottle and add some charcoal to the bottom. This will prevent fungus and algae. Take a 6-inch stem cutting from an existing plant and place it into the jar.
Keep your plant in a bright spot that gets indirect light. Change the water every three to four days. You can also add a drop of liquid fertilizer to the water occasionally to feed the plant.
30. Pothos (Epipremnum aureum)

31. Rubber Plant (Ficus elastica)
Growing a rubber plant in water will help to keep it much more compact than if you were to grow the plant in soil. Take a stem cutting around 6 to 8 inches long and remove any leaves on the bottom half of the stem. Place the stem into a glass jar or bottle and keep it in a bright spot out of direct sunlight. It might take around 3 to 4 months before you’ll start to see roots growing.
32. Spider Plant (Chlorophytum comosum)
Spider plants are extremely easy to grow in water by using the ‘pups’ that are produced along the stems of the plant. Clip these baby plants off the main stem and place them in a jar or bowl of water. Change the water once a week if it starts to get cloudy.
33. Wandering Jew (Tradescantia pallia, fluminensis, or zebrina)
When grown in the garden, a wandering jew can soon become a pest and take over as it spreads quickly and freely. However, growing this plant in water indoors means that it’s easily contained, and you can enjoy the colorful foliage, especially if you choose one of the variegated varieties.
