Definition: Growing Flowers from Seed Indoors

When I talk about growing flowers from seed indoors, I mean starting seeds inside your home or greenhouse, then moving the young seedlings outdoors once the weather warms up. You’re not growing the flowers inside all season, just giving a healthy head start during the colder months.

This method helps seeds germinate more reliably and protects tender seedlings from unpredictable weather. This lets you enjoy earlier blooms in your garden once spring arrives.

17 Easy Flowers to Grow From Seed Indoors

Here is a list of the easiest flowers to grow from seed indoors. At least they have been for me.

1. Zinnias

Zinnias are definitely among the favorite flowers for beginners starting seeds indoors. They sprout quickly, settle into the garden with no hesitation, and reward you with nonstop blooms all summer long.

Once they get going, zinnias thrive on being cut. Each harvest encourages even more flowers, making them a true workhorse in the cut flower garden.

They also bring the garden to life in the best way. Butterflies, hummingbirds, and bees love them, and my favorite time to wander through the cut flower beds is early evening, when bumblebees curl up inside the zinnia blooms for the night. It’s one of those small, magical garden moments that never get old. And I have the pictures to prove it!

Why it’s beginner-friendly: Zinnias are fast-growing, forgiving, heat-tolerant, and bloom continuously with regular cutting.

2. Marigolds

Marigolds are one of those dependable flowers that quietly do a lot of work in the garden. They’re easy to grow, unfussy about soil, and tough enough to handle less-than-perfect conditions without missing a beat.

I especially love marigolds for their role as companion plants. Their naturally strong scent helps discourage pests like aphids and mosquitoes, and while no flower is completely deer-proof, marigolds tend to be far less appealing to pesky nibblers. That makes them a great addition to both cutting gardens and vegetable beds.

Beyond their practical benefits, marigolds add cheerful pops of color all season long and still manage to attract bees and butterflies. If you’re looking for a low-maintenance flower that earns its place in the garden, marigolds are a solid choice.

Why it’s beginner-friendly: Hardy, adaptable, and naturally pest-resistant, marigolds thrive with minimal attention.

3. Cosmos (cosmos bipinnatus)

Cosmos bring an effortless, airy beauty to the cut flower garden. Their daisy-like blooms and soft, ferny foliage add movement and a relaxed, cottage-garden feel to summer bouquets.

These flowers are surprisingly tough once established. Cosmos sprout quickly, grow steadily, and seem to thrive even in less-than-ideal soil, often blooming happily where fussier plants struggle. They don’t demand much attention, which makes them a great option for gardeners who prefer a more hands-off approach.

Cosmos bloom generously from early summer right up until the first frost, and pollinators love them just as much as we do. Bee,s and butterflies are frequent visitors, adding even more life and movement to the garden.

Why it’s beginner-friendly: Fast-growing, drought-tolerant, and happy in poor soil, cosmos are easy-going flowers that bloom for months.

4. Sunflowers (Helianthus)

Sunflowers bring instant joy to the garden and feel like pure summer on a stem. Their bold blooms are magnets for pollinators, with bees buzzing around the flowers and birds eagerly waiting for the seed heads to mature.

One of the things that makes sunflowers especially interesting is their usefulness beyond their looks. They’re known for improving soil by absorbing certain toxins, and once the flowers fade, the seeds can be left for the birds or harvested to enjoy yourself.

Sunflowers are also wonderfully beginner-friendly. They’re easy to grow, don’t require much hands-on care, and grow quickly once established. Taller varieties appreciate extra support as they grow, especially in windy spots, but that’s a small effort for such a big payoff.

Why it’s beginner-friendly: Fast-growing, low-maintenance, and highly rewarding, sunflowers make an easy addition to any cut flower garden.

5. Sweet Peas (Lathyrus odoratus)

Sweet peas are beloved for a reason. Their soft, old-fashioned fragrance is unmatched, and they’re one of my very favorite flowers to grow in the cutting garden. Every year, they’re the first seeds I sow, which feels like the true beginning of the gardening season for me.

These early bloomers are among the first flowers to welcome late spring and early summer, filling the garden with delicate color and scent. Sweet peas are perfect for vertical growing, happily climbing trellises, fences, and arbors while adding height and movement to the garden.

They’re also surprisingly easy to start from seed indoors. Their large seeds are simple to handle, germinate quickly, and grow steadily, making them a great confidence booster for beginners. As a bonus, sweet peas attract beneficial insects that help support a healthy, balanced garden.

Why it’s beginner-friendly: Large seeds, quick germination, and early blooms make sweet peas easy and rewarding to grow from seed indoors.

6. Snapdragons (Antirrhinum majus)

Snapdragons are classic cut flowers with a bit of personality. Their tall spikes and dragon-shaped blooms add structure and height to bouquets, making them especially useful when you want arrangements to feel fuller and more balanced.

What sets snapdragons apart is their performance in cooler weather. They shine in spring and fall gardens, blooming generously when many summer flowers are still getting started, or winding down. With a wide range of colors, from soft pastels to bold brights, they’re easy to mix into almost any color palette.

Snapdragons are also reliable growers once established. Bees and butterflies are frequent visitors, and with just a little patience early on, these flowers settle in and keep producing. They’re a great option for gardeners who want dependable blooms with a longer seasonal window.

Why it’s beginner-friendly: Cool-tolerant, productive, and long-lasting in arrangements, snapdragons reward a little early care with weeks of blooms.

7. Shasta Daisies (Leucanthemum × superbum)

Shasta daisies are one of those flowers that instantly brighten the garden. With their crisp white petals and sunny yellow centers, they have a simple, classic look that never feels out of place. They’re also wonderfully low-maintenance, and a little deadheading goes a long way toward keeping the blooms coming.

They flower steadily through summer, and every time I share photos of mine, I get the same comment over and over, that they’re just such a happy flower. I couldn’t agree more. There’s something about a patch of daisies in full bloom that feels cheerful and timeless.

Shasta daisies are great for pollinators, attracting butterflies and other beneficial insects, and they tend to be less appealing to deer than many other garden flowers. If you’re looking for an easy, feel-good flower that brings reliable summer charm, Shasta daisies are a lovely choice.

Why it’s beginner-friendly: Hardy, long-blooming, and easy to care for, Shasta daisies thrive with minimal effort.

8. Celosia

Celosia stands out in the cut flower garden with its bold, sculptural blooms. From feathery plumes to velvety crests and upright spikes, these flowers add texture and drama that instantly elevate summer arrangements.

Celosia is also a strong performer once established. It thrives in warm weather, handles dry conditions well, and keeps blooming steadily through summer and into fall. That combination makes it a reliable choice for gardeners in hotter climates or anyone looking for flowers that don’t fade when the temperatures rise.

Bees and butterflies are frequent visitors, and the long-lasting blooms bring both color and structure to the garden for months. If you want a flower that offers something a little different while still being easy to grow, celosia is a fantastic option.

Why it’s beginner-friendly: Heat-tolerant, drought-resistant, and highly productive, celosia delivers bold color with minimal care.

9. Calendula (Calendula officinalis)

Calendula is one of those quietly hardworking flowers that earns its place in the garden. Its cheerful orange and yellow blooms are well known for their traditional medicinal uses and are often used in salves, oils, and teas to soothe skin and support healing. The petals are also edible, adding a pop of color and a slightly peppery flavor to salads and other dishes.

This cold-tolerant annual blooms early and continues to bloom for months. In mild climates, calendula can flower from early spring straight through fall, and sometimes even into winter. It’s an especially nice choice when you want flowers in the garden before summer really gets going.

Calendula fits beautifully into vegetable gardens, borders, and mixed plantings. It attracts beneficial insects, requires very little care, and brings steady color with minimal effort, making it a great option for gardeners of any experience level.

Why it’s beginner-friendly: Cold-tolerant, easy to grow, and useful both in the garden and beyond, calendula is as practical as it is pretty.

10. Bachelor’s Button (Centaurea cyanus)

Bachelor’s Buttons, also known as cornflowers, bring a soft, old-fashioned charm to the garden with their delicate blooms in shades of blue, pink, purple, and white. They’re one of those flowers that look dainty but are surprisingly tough.

These are incredibly easy to start from seed indoors and don’t demand rich soil to thrive. In fact, they seem to enjoy being a little neglected. I was genuinely surprised to see mine self-seed the following year, popping up through the cracks in my pavers with no irrigation at all. That kind of resilience makes them hard not to love.

Once established, bachelor’s buttons are drought-tolerant, low-maintenance, and generous bloomers. Their nectar-rich flowers attract bees and butterflies, adding even more life to the garden. They’re also versatile in arrangements, working just as beautifully in fresh bouquets as in dried arrangements.

Why it’s beginner-friendly: Easy to start from seed, tolerant of poor soil, and happy with minimal care, bachelor’s buttons are wonderfully forgiving.

11. California Poppies (Eschscholzia californica)

California poppies bring a relaxed, wildflower feel to the garden with their bright, cheerful blooms. These sun-loving plants thrive in dry conditions and don’t ask for much, making them ideal for gardeners who prefer a more hands=off approach.

One of their best qualities is their ability to self-sow. Once established, California poppies often return year after year, creating a natural, ever-changing display with very little effort. They’re especially well-suited to poor soil, where fussier plants tend to struggle.

Bees and butterflies are drawn to their open flowers, adding movement and life to the garden. If you’re looking for an easy, low-maintenance flower that brings color without constant care, California poppies are a wonderful choice.

Why it’s beginner-friendly: Drought-tolerant, self-seeding, and happy in poor soil, California poppies thrive with minimal attention.

12. Black-Eyed Susans (Rudbeckia hirta)

Black-eyed Susans bring an easy, sun-washed charm to the garden and feel right at home in more relaxed, cottage-style spaces. With their golden-yellow petals and dark centers, they’re classic late-summer flowers that signal the shift toward early fall.

These plants are wonderfully resilient. Once established, they handle a wide range of growing conditions with very little fuss, making them a great choice if you want dependable color without constant care. They bloom generously from early summer through September, filling gaps when other flowers start to slow down.

Black-eyed Susans also support the garden ecosystem in a meaningful way. Bees and butterflies visit the blooms during the growing season, and once flowering ends, the seed heads provide food for birds through winter. It’s a flower that gives long after its blooming season is over.

Why it’s beginner-friendly: Hardy, adaptable, and long-blooming, black-eyed Susans thrive with minimal maintenance.

13. Pansies (Viola × wittrockiana)

Pansies are little bursts of cheer when the garden needs it most. They shine in cooler weather, bringing color to early spring, fall, and in milder climates, even winter, when most flowers are taking a break.

What makes pansies especially useful is their cold tolerance. They handle chilly temperatures with ease and keep blooming long after other plants have faded. Their soft, velvety faces come in an incredible range of colors, and as a bonus, the blooms are edible, with a mild, slightly sweet flavor that works beautifully in salads, desserts, and garnishes.

Pansies are easygoing plants that don’t require much attention, yet they still attract pollinators, such as butterflies, when conditions allow. If you’re looking for dependable color during the shoulder seasons, pansies are a simple and rewarding choice.

Why it’s beginner-friendly: Cold-hardy, low-maintenance, and long-blooming, pansies thrive when many other flowers won’t.

14. Strawflowers (Xerochrysum bracteatum)

Strawflowers are one of those plants that earn their keep long after the garden season ends. What I love most about them is their papery texture, which makes the blooms just as beautiful dried as they are fresh. They hold their color and shape incredibly well, making them a favorite for everlasting arrangements.

These sun-loving flowers thrive in hot, dry conditions and don’t require rich soil to perform well. Strawflowers are especially useful in spots where toerh plants struggle, bringing reliable color and structure without demanding much attention.

They bloom steadily from summer through fall, attracting bees and butterflies along the way. If you’re looking for a hardworking flower that delivers both in the garden and indoors, strawflowers are an easy win.

Why it’s beginner-friendly: Drought-tolerant, low-maintenance, and long-blooming, strawflowers thrive with minimal care and dry beautifully.

15. Larkspur (genus Delphinium)

Larkspur brings instant height and drama to the garden with its tall, graceful spikes of delicate blooms. Flowering in early to mid-summer, these airy stems are covered in shades of blue, purple, pink, and white, making them especially useful for adding vertical interest to beds, borders, and bouquets.

I love how larkspur creates a natural backdrop for other flowers, giving the garden a layered, cottage-style look. The blooms are also popular with bees and butterflies, adding movement and life during the early part of the season.

Larkspur is easy to grow from seed and often self-sows, returning year after year with very little effort. One thing to note is that all parts of the plant are toxic if ingested, so it’s best to handle it with care and plant it thoughtfully, especially in gardens with pets or small children.

Why it’s beginner-friendly: Easy to grow from seed, naturally self-sowing, and low-maintenance once established.

16. Sweet Alyssum (Lobularia maritime)

Sweet alyssum is one of those quietly charming plants that fills in all the little gaps and makes the garden feel finished. Its tiny, honey-scented flowers form a soft carpet of blooms that spill gently over edges, containers, and garden borders from spring through fall.

This easygoing plant grows quickly and requires little attention once it’s established. It tolerates dry conditions well and often reseeds, returning year after year without much effort. Available in shades of white, pink, purple, and soft yellow, sweet alyssum blends beautifully with almost anything planted nearby.

Pollinators love it, too. Bees and butterflies are frequent visitors, making sweet alyssum a wonderful choice if you want to support beneficial insects while adding a light, airy touch to your garden.

Why it’s beginner-friendly: Fast-growing, self-seeding, and low-maintenance, sweet alyssum thrives with very little care.

17. Coneflower (Echinacea spp.)

Coneflowers are garden staples for good reason. These native North American perennials bring bold, long-lasting color to the garden with sturdy stems and distinctive, raised centers surrounded by petals in shades of purple, pink, red, yellow, and white.

They bloom generously from early summer through fall, often filling in as other flowers begin to slow down. Coneflowers are magnets for pollinators; bees and butterflies visit throughout the season, and goldfinches love the seed heads later on, adding movement and interest long after the blooms fade.

Once established, coneflowers are impressively resilient. They thrive in hot, dry conditions, tolerate drought well, and don’t require much hands-on care. Beyond the garden, echinacea has a long history of herbal use and is commonly associated with immune support, making this plant both beautiful and purposeful.

Why it’s beginner-friendly: Hardy, drought-tolerant, and long-blooming, coneflowers thrive with minimal maintenance year after year.
