Everyone wants lovely flowers in their yard, but for DIY gardeners, caring to the soil for long periods of time may be demotivating. Previously, there was little you could do to resolve the issue. With the emergence of hydroponic systems, however, all gardeners now have a clear option.

Hydroponic systems reduce the need to spend hours tending to the soil, as well as another major garden hazard: weeds. As a result, we’ve compiled a list of 15 hydroponic flowers that may be grown in a small area and in a range of systems.

Flowers Grown in Hydroponics 15 Beautiful Hydroponic Flowers

Orchids are number one.

Orchids are valuable flowers, but they may be picky about their growth circumstances since they are susceptible to contaminated medium, which can lead to health issues. When cultivating orchids, however, there is a method to avoid these hazards by employing a hydroponic system. This is because most orchids are epiphytes, which means they don’t need much soil and get most of their moisture from the air.

Growing orchids in water provides them with the ideal circumstances for soaking up the required quantity of moisture. As a result, aerial roots stay dry, which keeps diseases at bay.

Here are some suggestions for hydroponically cultivating orchids:

Because orchids demand a lot of light, it’s vital to supply them with the best lighting possible, but direct light should be avoided at all costs.

Make sure your grow tank is clean while growing epiphytic orchids, since their roots need light to photosynthesize.

Orchid flowers may last up to six months, making them outstanding plants to raise.

Petunia is number two.

These well-known South American flowers thrive in hot weather. Many gardens, both in borders and in containers, have them. One of the reasons they are so popular with gardeners is because they come in an almost unlimited array of colors.

The bulk of petunias available are hybrids developed for particular purposes. As they develop, they may reach anywhere from six inches to four feet tall with a three-foot spread. You’ll need a lot of branch support and a lot of room to minimize congestion.

Petunias need at least 5-6 hours of direct sunshine to flourish. They prefer warmer conditions during germination, following which they may be moved to colder regions.

Zinnia (no. 3)

Zinnias are simple to cultivate daisy-like blooms. They are only found in the southern United States and South America, and enjoy full sun. These bright plants need at least six hours of direct sunlight or intense light to thrive.

When completely grown, they may reach heights of 4 to 40 inches. This means you’ll need help as well as a growing medium that can support your root system.

Due to their vast range of dazzling hues and capacity to withstand hotter temperatures, they are popular for growing in many garden situations. Zinnias will self-seed every year. You’ll get more bang for your buck if you choose from the numerous varieties available for your hydroponic garden.

Amaryllis (no. 4)

This flower comes in a wide range of colors and varieties, and it’s often used as a houseplant in temperate climates. Even if you want to plant these plants in soil later, hydroponics is the best way to get the large, spherical bulbs to root.

There’s no reason you shouldn’t keep growing it until its gigantic petals twinkle like a star in your living room.

Even the most simple Kratcky method, which entails putting a plant in a jar with its roots in water and drying it from the base of the stem up, may be adapted by Amaryllis.

Remember that a simple deep-water culturing system will suffice. You may also place the bulb right in the growing media (such as potting soil).

#5. Iris

With its three-bloom inflorescence, iris is one of the most adaptable plants you’ll ever encounter. Some plants thrive on tough clay soil, marshy swamps, and even water ponds.

From there, the transfer to hydroponics is simple. Iris variegata, Iris tectorum, and Iris versicolor, as well as cultivars like ‘John Wood,’ ‘Between the Lines,’ and the magnificently named – and colored – ‘Sun Moon Lake,’ are more naturally suited to growing in water.

The flowers are similarly one-of-a-kind, having specific names for each of the petals. As a consequence, the three upward-facing petals are known as “standards.”

Carnations, #6

Carnations are one of the most popular hydroponic flower varieties. They are also one of the most commercially farmed flowers due to the enormous number of individuals who use them as interior decorations.

Carnation petals have a lovely smell and instantly make any area seem more pleasant. The leaves are very edible and have a good taste.

A common method is to take cuttings and cultivate plants from them. It may take two to three weeks to start from seeds and propagate in soil. Hydroponics may help speed up this process.

Snapdragon (#7)

Snapdragons are known by the scientific name Antirrhinum, which means “like a nose.” Their vibrant colors and flowers, which mimic a dragon’s mouth when pressed, have made them a popular option.

Snapdragons may grow to be anywhere from 6 and 48 inches tall, depending on the variety and growing conditions. This means your plant may want some assistance, which the growth medium will have to provide.

Snapdragons are typically grown inside before being transplanted, even when grown in a soil-based medium. Because of their acute sensitivity to meteorological conditions, this is the case.

Snapdragons are also available in a range of colors, including pink, purple, and white.

Dahlias (#8)

Dahlias are related to sunflowers, daisies, zinnias, and chrysanthemums. Dahlias are octoploids, which means they contain eight homologous sets of chromosomes.

Make sure they have enough of area if you’re growing them in a hydroponic system. Because you’ll be planting in a container, it should be at least 12 inches deep. Some types need a closer look, which might rule them out of your system.

Dahlias are also half as wide as they are tall, necessitating a lot of lateral space.

Dahlias need a lot of light and consume a lot of food. Your growth medium should dry out between watering cycles, and you’ll need to keep an eye on your tank levels.

Gerbera (nine)

While many people choose annuals or bulbous plants for their hydroponic garden, perennials with long blossoms may be extremely lovely. Gerbera blossoms, which are Asteraceae family members and look like exotic daisies, last for weeks.

This plant, which is native to tropical places across the globe, comes in a variety of colors, including white, light purple, yellow, pink, orange, and red. Flowers in two hues are also available if you desire contrast.

Here are a few pointers to keep in mind while you cultivate it:

Apples, broccoli, eggplant, lettuce, sweet potatoes, and cucumber are all ethylene-producing plants that should not be cultivated near them.

Keep the temperature between 40 and 70 degrees Fahrenheit (5 to 20 degrees Celsius).

Keep your plants out of direct sunlight to avoid burning the leaves and maybe damaging the blossoms.

Overall, this plant is an excellent choice for hydroponic flowering.

Freesia is the tenth flower on the list.

Freesia is a bulbous flower that grows readily in a hydroponic garden and has one of the most beautiful and unique sweet scents of all the flowers. Flowers in the colors of white, yellow, purple, orange, and red may be utilized to bring a little spring happiness into your home.

When you go into a room full with freesias, you’re immediately drawn in by their strong scent, which is followed by their lovely inflorescences and long, linear leaves.

The following are some helpful hints for caring for this plant:

Keep the bulb-like component of the plant dry at all times; the optimal nutritional solution is a 25-50-75 ratio; and, to break the dormancy of the corms, keep them at 86 degrees Fahrenheit or similar circumstances for 12 weeks.

This attractive plant has the ability to improve the look of any room or garden landscape.

Peace Lilly (#11).

Spathiphyllum is a perennial favorite if you just want a pleasant house plant to grow hydroponically.

The “spathe,” a modified leaf that serves as a magnificent background to the “spadix,” a long inflorescence that rises like a candle from its center, gives this exotic plant its name.

It has decorative and architecturally noteworthy leaves. You have to acknowledge that their deep green and waxy, delicately veined, and rich dark green chordate-shaped leaves match the blossoms.

Keep in mind that chlorine is particularly toxic to peace lilies. As a consequence, make sure the feeding solution is free of chlorinated water. If all you have is tap water, don’t panic; just put it in a jug and let it for 30 minutes to enable the chlorine to disperse.

Chlorine is more often found in dirt bins. If this is the case, clean the roots well before moving them to a hydroponic system.

Hyacinth (#12).

Hyacinths are a simple hydroponically grown plant, so much so that it may be a reason to spend quality time with your kids and, why not, educate them about nature and flowers.

When the dormant period starts, the advantage of using hydroponics for this flower is that you won’t have to take the bulb from the soil. Hyacinth bulbs do not survive the winter in the ground in most temperate climates.

Hyacinths produce a lot of seeds in a short amount of time. Remove the stem as soon as the blossoms fade to prevent this. If you don’t, you’ll have a weaker bloom the next year.

Once the bloom is done, cut the stem 12 inches below the inflorescence because the bulbs are delicate. This ensures that all of the plant’s energy is sent back into the bulb.

Once the stem has dried, you may clip it entirely off. However, do not pull it off. Finally, keep in mind that these magnificent flowers only bloom for a brief period of time; using an organic blooming fertilizer might help them grow for longer.

Rex Begonias (#13).

In every sense, Rex Begonias are unique. Rather than blossoms, we distinguish them by their leaves and foliage. Even better, they’re colorful and look to be painted on top of the thick fibrous leaves. Maroon, purple, grey, silver, pink, and red are just a few of the color options.

In 1856, Rex Begonias were found in an orchid shipment to England, and no one understood what they were. South America, Africa, and Southeast Asia are all home to this tropical plant. There are 1,831 different begonia species, each with its own distinct leaf appearance.

Because they are tropical and subtropical plants, Rex Begonias are native to the tropics and subtropics. They make wonderful houseplants since they need very little light and like to stay in the shadow.

These plants may grow to be anywhere between 12 and 24 inches tall. With leaves averaging 4-5 inches in length, it’s also crucial to monitor the amount of space necessary for outward expansion.

Daffodils (#14).

Because of its short vegetative period, this flower has long been a popular hydroponic plant. Even with a rudimentary Kratky method, it can be easily cultivated.

When the plant becomes dormant in the soil, you may leave the bulbs in the ground. You’ll need to keep it chilly, dark, and dry if you’re growing it hydroponically.

If you deadhead the bloom after it has gone, your plant will dedicate more energy to fattening the bulb.

Make sure all of the leaves have dried before removing the bulb from your hydroponic garden or vase.

Finally, it looks great in a simple yet elegant vase or even a cheap jug.

Echinacea is a herb that is used to treat a variety of ailments.

The American Cone Flower, often known as Echinacea, is a lovely flowering plant that is also used to make a medicinal herbal tea. Echinacea roots, leaves, and flowers are used in the mix.

Echinacea is said to enhance the immune system, lowering the symptoms of colds, flu, and a number of other disorders, according to herbalists.

Dwarf echinacea plants tend to be roughly 16 inches tall, while standard echinacea plants grow to be 2 to 4 feet tall. The spread on normal is 1 1/2 to 2 feet, whereas it’s a foot or less on dwarf.

The pH of an Echinacea feeding solution should be between 6 and 7. Despite the fact that they can withstand a broad range of temperatures, the quality and yield will vary.

If your nutrition solution or growth medium is too alkaline or acidic, many critical nutrients will be lost because they will not be absorbed by the plant.


Flowers often utilized in floristry are usually good candidates for hydroponic growing. Carnations, gerbera daisies, and snapdragons are finicky about their growth conditions and are susceptible to fungi like fusarium wilt. This makes them good candidates for a more controlled growing technique, and hydroponic frameworks usually work well for them.

Don’t restrict yourself to your usual outside garden flowers; houseplants are also fantastic options for hydroponic growing. With only a few cuttings, you may start a hydroponic collection of peace lilies, hoya, Rex begonias, or beautiful jasmine vines. Yes, it’s that practical!

Hydroponic flowers are a great way to grow your own plants without the need of soil. They require less maintenance and can be grown in small spaces. The “hydroponic flower seeds” are a good place to start when growing your own indoor or outdoor plants.
