13 Easiest Seeds To Grow Indoors

With the multitude of available avenues to procure plants nowadays, it may seem unnecessary even to attempt to grow your own plants from seed. However, there is a special sense of fulfillment and achievement when the full-grown plant you are admiring in front of you was once a seed that you yourself nurtured a few months before.

You do not need to challenge yourself excessively by attempting to grow a difficult plant from the outset. Rather, why not try some plants that are easy to grow and work your way up the difficulty scale?

In this article, we will list some of the easiest seeds to grow in a small, indoor garden. We will include both flowering plants and some vegetables. So, if you are thinking about starting an indoor garden and are looking for plants to include, then keep reading.

13 Easiest seeds to grow indoors

1. Coleus

The coleus plant is a popular indoor houseplant with leaves that come in a variety of color combinations. Its luscious pink, green and purple colors are even more pronounced when they are not under direct sunlight, which means they do well as indoor plants.

You can choose from a multitude of coleus varieties, but the process of growing them from seed will be virtually the same for all.

Fill your chosen container with starting soil and add the coleus seeds to it. Make sure the soil is always moist but never soggy, and keep the container in a room where the temperature is constantly between 65 and 85 degrees Fahrenheit. The seedlings should start appearing around two to three weeks after planting the seeds.

When the seedlings start to appear, transfer the container to a spot where they can get a little more light so they can continue to grow. A spot next to a window should be fine. If you planted the seeds in the fall or winter when light is scarce, you can help the seedlings out by buying a grow light.

2. Asparagus fern

Also known as Sprenger’s asparagus, this plant is actually neither of its namesakes. It is a plant native to South Africa and is a great little addition to any indoor garden.

You can buy the seeds as they are, but you can also use the seed inside the asparagus fern berry. Just remember to wear protective gloves when handling these berries because they can be an irritant on the skin.

If you are taking the seeds from the berries, cut the berries open with a small knife to easily remove the seeds. Once removed, let them dry out and then scarify them using some sandpaper. This will jumpstart the germination process.

Take your container and fill it about one third with starting soil, then place the seeds in the soil. Cover the seeds with what is left of the soil, moisten the soil a bit, and cover it with some plastic film wrap.

Keep the container at room temperature and the seedlings should start to appear after three to four weeks. Then, move the container to a spot where it can get more sunlight.

3. English ivy

The English ivy is a fast-growing plant that can reach substantial lengths if you allow it to grow unhindered. This is the perfect plant for someone who may be impatient and eager to see results as soon as possible.

Once you have got hold of your English ivy seeds, do not be too eager to plant them immediately. You will need to keep the seeds in your refrigerator for one to two months. After they have chilled in your fridge for that time, take them out and dump them into a bowl of water. Make sure the water in the bowl stays at room temperature and keep the seeds there until the following morning. This entire process will ensure that the seeds germinate faster.

In a shallow container, add about a quarter-inch layer of starting soil and place the seeds on top, making sure they are not buried underneath the soil. Moisten the soil and keep it that way until the plants start to grow.

4. African violet

If you want to add a flowering plant to your indoor garden, you can never go wrong with an African violet. There are over 20 different species of African violet for you to choose from, so you can plant several different kinds for a mix of colors and hues.

You can, of course, grow new African violets from cuttings, but growing them from seed is also completely doable.

The best medium for this plant is a mixture of milled coconut, perlite and peat moss. Moisten the potting mix before putting it in the container, then place the seeds in the mix and cover the container with plastic wrap. The plastic wrap is there in order to maintain the level of humidity required by the seeds to germinate.

Place the container at least 10 inches below a grow light for around 12 to 14 hours a day.

Once the seedlings are two inches wide, you can transfer each one to its own individual pot.

5. Peace lily

Another great choice of flowering plant for your indoor garden is the peace lily. The white flowers produced by this plant are one of its most appealing traits. While it is perfectly possible to grow this plant from any stage of its life, growing it from seed and eventually seeing the flowers just might feel a little more fulfilling.

When preparing the soil to plant the seeds, make sure you are not using too little or too much soil. Base the amount of soil on the size of the seeds, making sure there is enough to lightly cover them. Moisten the soil with a little water.

After a few weeks, the seeds will start to soften and turn yellow as they mature further.

Do not expect the plant to produce flowers in the same year; the peace lily can take several years before it starts to bloom.

6. Cactus

Cacti, and other succulents for that matter, are good plants to add to your indoor garden because of how low-maintenance they are.

You can always use a piece of cactus cut from a mature plant to grow a new cactus, but you can also grow a cactus from a seed.

There are close to 2,000 species of cactus, so it is entirely up to you what kind you want to grow in your garden. Cacti come in all shapes and sizes that can be mixed and matched with your existing plants.

Choose the cactus you want to grow and plant the seeds in starter soil with a little compost. The compost should preferably have some moisture and grit in it. Push the seeds a little way into the soil and compost mixture. You can also mix in some perlite or vermiculite before placing plastic wrap over the container and placing it in a warm room.

After a couple of weeks, the seedlings should start appearing and you can then remove the plastic film. If the potting mix looks dry, add just a little water to moisten it again.

When the seedlings start turning into cacti, you can plant each one in its own pot.

7. Lithops

The Lithops succulent, also called the living stone, is one of the more unique-looking succulents you can add to your indoor garden. Mature lithops plants look like bunches of rocks, and they come in an assortment of colors and shapes.

Prepare the potting mix for your lithops by adding one part perlite to one part regular potting soil. Moisten the potting mix and place it in a pot, then place the seeds on top of the potting mix and cover them with a layer or fine sand about an eighth of an inch thick.

Make sure the soil is never fully dry while waiting for the seeds to germinate. Place some plastic wrap over the container to maintain humidity.

The temperature where the pot is kept should be between 65 and 80 degrees Fahrenheit. The germination of the lithops seeds can take several weeks to a few months. Only remove the plastic wrap when the seedlings appear. Wait until a year after you planted the seeds before transferring the seedlings into individual pots.

8. Cat grass

One of the easiest plants to grow in an indoor garden, which also has added benefits for your pets, is cat grass.

Cat grass is native to Europe, Asia and Africa, and gets its name because cats love to nibble on it. It can lift their mood and can also make them feel better if they have an upset stomach.

Poke drainage holes at the bottom of a shallow container, and fill the container about three-quarters with potting soil. Moisten the soil and sprinkle the seeds onto it. Place the container in a spot where it gets lots of bright, indirect light and where the temperature is around 50 to 80 degrees Fahrenheit. Place plastic wrap over the container.

You will notice new growth as soon as a few days after planting the seeds. Remove the plastic wrap and transfer the container to an even sunnier spot. Before long, the cat grass will have grown several inches and you can now offer it to your cat to eat or play with.

9. Cauliflower

Cauliflower can be grown from seed and, because it takes the vegetable a long time to mature, you can start the growing process in your indoor garden before transferring it to your outdoor vegetable garden.

Plant the seeds in your indoor garden at least a month before your spring planting date. When the seeds germinate and turn into seedlings, they will be just in time to be transferred to your outdoor garden.

There are different varieties of cauliflower, so you can choose different colors to make your garden both pretty and multifunctional.

10. Brussels sprouts

As with cauliflowers, Brussels sprouts also take their sweet time between germination and mature vegetables. Start the planting process a month before you plan to transfer them to your outdoor garden with all your other vegetables.

If you live in an area where there are cold winters and you happen to plant your Brussels sprouts close to winter, make sure you protect your crop from the cold.

11. Tomatoes

A popular plant to grow in your indoor garden is the tomato. Not only are these easy to grow; they are important ingredients for a multitude of dishes. There are different kinds of tomatoes, so choose the variety that you enjoy cooking and eating so that your gardening efforts will not be in vain.
Sow the tomato seeds one-and-a-half months to two months before the estimated last frost.

Only plant the seedlings in your outdoor garden when there is no frost left on the ground outside.

12. Watermelon

Make sure you do not damage or disturb the seedlings’ roots when you transplant them, as this could affect the plants’ growth over the long term.

Remember that there are many different kinds of watermelon, so you can get creative with the types you would like to include in your indoor garden.

13. Basil

Growing herbs indoors is a great way to maximize both the space in your garden as well as the effort you put into planting these seeds.

Basil is a very versatile herb that can be incorporated in a lot of different dishes, so it is almost a no-brainer to grow your own basil plant.

There are different types of basil; do not be afraid to experiment with other varieties aside from the typical green basil.

Basil does not do well in the cold, so it is better to let the plant germinate indoors. Plant the seeds at least a month before you plan to transfer them to the outdoor garden.
