Read on to find out more about the easiest flower plants to grow from seed, or scroll down to see the full infographic at the bottom of the page.


Always a favourite with kids – they’ll definitely be impressed with Sunflower ‘Mongolian Giant’ growing up to 14 feet tall! Just sow the seeds straight into the ground in a sunny, sheltered spot and watch them grow and grow and grow! Be sure to provide the stems with supports to grow the tallest sunflowers around.

Sweet Peas

Irresistable fragrance and prettiness! And the more you pick, the more flowers they produce! The large seeds of sweet peas are easy to handle, but if sowing sounds complicated then buy them as sweet pea plug plants! A sunny spot, a supportive fence, and regular watering is all these climbers need to produce your own ‘home grown’ cut flowers. Just keep an eye out for mice, slugs and snails – they love the young shoots. Consider covering with a mini cloche, or even a cut-off plastic bottle.

Nigella (Love in A Mist)

Nigella is an incredibly easy plant to grow. Simply scatter nigella seed across a patch of bare soil and let it look after itself! With jewel-like flowers and delicate ferny leaves, nigella is much tougher than it looks. As the flowers fade, this pretty plant will set seed for the following year. What could be simpler!


Aquilegias are easy plants to grow from seeds and will come back year after year. Start aquilegias in small pots for transplanting later on. Once they’re established they’ll self-seed, so you’ll always have fresh plants each year. They tolerate almost any conditions in sun or semi-shade, and their pretty bonnet-like flowers come in almost every imaginable colour combination.

Eschscholzia (Californian Poppy)

If you are not a fan of watering then Eschscholzia make easy to grow plants for your garden. These colourful little annuals thrive in poor, dry soil and full sun so they are perfect for filling forgotten corners of the garden. Just scatter them where you want them to flower and let them take care of themselves. Each year they will set seed which will grow the following summer, creating effortless drifts of colour.


Quick-growing and colourful, nasturtiums are easy plants for children to grow. Sow them in borders as ground cover or let them spill out of containers. The large seeds can be sown directly into the soil – just wait until after the last frosts. Their peppery leaves and flowers complement and garnish summer salads.


These easy to grow bedding plants are another great choice for young gardeners. Marigold seeds are easy to handle, and grow quickly so you’ll have a short wait for their colourful flowers. From tall varieties for the border to small types for beds and containers, there’s a marigold to suit every sunny spot in the garden.

Hardy Geranium (Cranesbill)

Cranesbill is so popular because it’s a reliable, low maintenance, ground cover that will wander through your borders year after year. Hardy geraniums are not difficult to grow from seed but you can grow them from bareroots which is even simpler.


Easy to grow patio plants when grown from plugs, and best loved for adding colour to hanging baskets and containers. Fuchsias come in all colours and shapes, from trailing to upright you could even try the climbing fuchsia ‘Lady Boothby’ for an ambitious display. For a really professional look, pinch out the very tips of each stem while the plants are still young to encourage lots of bushy growth. Fuchsia erries are edible, but not always tasty!


With their cheery faces, it’s hard to resist the appeal of pansies. These garden favourites are easy plants to grow from seed but even easier from pansy plug plants. Whether you grow them for winter or summer colour, deadheading faded flowers will encourage more and more colourful blooms.

The 5 Best Flowers to Start Indoors from Seeds

Kayla and I are starting some flower seeds indoors to move outside when it gets warm enough. This is our first time growing seeds inside so we’re pretty excited. We wanted to share what varieties we’re growing and how to care for them so you won’t be intimidated to give a go yourself.

Today, I’m sharing the best flowers to start indoors from seed. Whether you’re an experienced gardener, or you’re just beginning, the steps below are straightforward.

The flower varieties I chose because they germinate and grow quickly. This means it won’t take long to have sturdy young plants to move outdoors. Or, continue to grow your flowers indoors for loads of color year-round.

1. Impatiens

Ok, I already hear you complaining about how tiny impatiens seeds are. You might be tempted to resort to the pelletized versions for easier handling. However, the coating on these seeds lowers their germination rates significantly, so resist the temptation.

Impatiens are the best flower for your shady spots and you’ll love how they
bloom nonstop from when you transplant them outside until the first frost. They grow from 6 to 30 inches tall. You can also choose from a huge range of multicolored and solid shades of white, purple, salmon, orange, red, and pink. We opted to try this seed mix as it’s our first time growing these flowers.

For hassle-free germination, make sure you provide adequate moisture, light, and warmth.

How to Start Impatiens Indoors

  • To start impatiens seeds, prepare a pre-moistened soil and sprinkle the seeds on it around 10 weeks before the last frost date.
  • Allow adequate light to reach the seeds. Don’t cover them before they germinate. Because we don’t have enough room near our windows, we’re using an LED grow light we bought on the advice of this great article.
  • The seeds need a temperature range between 70 and 80 degrees F
  • The seeds should sprout after 1 to 3 weeks
  • Transplant your flowers outside 1-2 weeks after the last frost date.

2. Sunflowers

Who doesn’t love sunflowers? They’re such happy looking blooms!

Do you ever wonder why sunflower seeds are always included in every kid’s pre-packaged garden kit? Well, the moment a sunflower seed is covered in warm moist soil, it sprouts.

We bought this mix of dwarf sunflowers because we want to keep them in pots on our front porch.

Sunflower seeds should be started indoors with loads of light. (They call them SUNflowers for a reason.)

How to Start Sunflowers Indoors

  • Sow your sunflower seeds 5 weeks before the last frost.
  • Plants the seeds half an inch deep in the soil, and keep the temperature between 70-85 degrees F.
  • Expect your seedlings to appear after 1-2 weeks, and transplant them after the last frost.

3. Marigolds

I was warned by my neighbor not to start marigolds indoors. But I read recently that French varieties are easier to grow and more disease resistant than their American counterparts. I opted for these pretty heirloom marigolds.

Marigolds will thrive in any climate. Start your seeds indoors to enjoy their bright orange and sunny yellow blooms. Sow your seeds around one and a half months ahead of the last frost date.

How to Start Marigolds Indoors

  • Cover seeds with a thin layer of soil
  • Keep the seeds between 70-75 degrees F
  • Expect your seeds to sprout after a week
  • After the last frost you can move your flowers outside

4. Alyssum

Did you know that some sweet alyssum seeds can germinate in only four days? Talk about instant gratification! What’s more, they mature super-fast to give you tiny fragrant flower masses to enhance the look of your spring garden and home. You will find these ground-hugging plants make an amazing edge for your containers, borders, or beds.

Alyssum flowers come in purple, white, yellow, or pink. I love the deep purple alyssum so we’re growing these.

How to Start Alyssum Indoors

  • Sow your alyssum seeds directly on the surface of your soil 8 weeks before the last frost date, and don’t cover them up.
  • Ensure that the soil temperature ranges from 60-75 degrees F.
  • Allow a week or so for germination
  • As the frost date nears, you can freely transplant your flowers.

5. Cosmos

As tough as nails, you only have to plant cosmos once and they’ll just keep growing. They are so easy to plant and grow, cosmos are a true no-brainer for an enthusiastic beginning gardener.

Cosmos typically come in shades of burgundy, pink, white, and lavender but chocolate cosmos are becoming trendy. We chose this pretty mix and I’m going to start some indoors and sow others as wildflowers in our backyard.

How to Start Cosmos Indoors

  • Sow your cosmos seeds between 4 and 6 weeks ahead of the last frost date.
  • Cover the seeds with an eighth of an inch of soil.
  • Keep them at around 70 degrees F until they sprout and then reduce the temperature by 10 degrees.
  • Give them plenty of light to avoid leggy plants.
  • You can transplant your flowers as the frost date nears.

Which of these beauties are you going to try starting indoors? I’m excited for Kayla to see these flowers go through the entire process from seed to flower.
