7 Flowers to Plant in June for Bold Late-Summer Color That Lasts Into Fall – They're So Easy to Grow

June is, without a doubt, something of a slightly chaotic point in the gardening year, as everything either feels like it’s racing ahead or already behind. But this is exactly the moment I like to lean into late-season planting, especially if the goal is that rich, full “second wave” of color that carries the garden from late summer into fall.

I know, I know; it sounds like a lot of work at a time when everything is already merrily ticking along. Across a wide range of USDA hardiness zones, however, June planting can actually be ideal, as the soil is warm, daylight hours are longer, and many perennials and hardy annuals establish quickly if they’re watered properly.

Admittedly, it’s less about perfection and more about momentum. The aim, above all else, is about getting roots down fast so plants can hit their stride when temperatures peak, and keep things feeling alive and abundant just when everything else starts to look a little... well, a little tired.

7 Flowers to Plant in June

If you stick to this list of flowers to plant in June, you will find that they are the kind of late bloomers that are critical for pollinators, especially bees and butterflies that are still active well into the warmer months.

For these little critters, a well-planted June garden can feel like a continuous buffet of nectar right through to the first frosts. So, without any further ado, here are seven of my favourite flowers to plant in June if you want that kind of long, late-season payoff that makes everyone (even someone as teeny as your birth month bug!) sit up and pay attention...

1. Coneflower

I tend to rave about coneflowers a lot, but they really are one of the best flowers to plant in June for late-season color that lasts into fall. Somehow both beautifully wild and completely dependable, they shrug off heat, drought, and poor soil, making them ideal for unpredictable summers.

Their daisy-like blooms in shades of pink, purple, and white appear from mid-summer right through into fall, especially if you deadhead regularly. They’re also a magnet for pollinators and seed-loving birds later in the season. And, hardy in USDA zones 3-9, they’re as tough as they are beautiful.

Plant something like the Magnus Purple Coneflower from Nature Hills for a non-drooping addition to your beds.

2. Black-Eyed Susan

I think we can all agree that if summer had a default setting, it would look like black-eyed Susans. Their golden-yellow petals and dark central cones bring instant brightness to any border, and they’re incredibly reliable once they get going.

Planted in June, they’ll establish quickly and start flowering in late summer, often continuing well into fall. They thrive in USDA zones 3-9 and are especially good for naturalistic planting schemes where you want movement, warmth, and wildlife value all in one. And, happily, there are plenty to choose from... although the Glitters Like Gold Black-Eyed Susan from Nature Hills is a pretty solid shout, thanks to its showy campfire-colored blooms.

3. Coreopsis

When it comes to flowers to plant in June for late-summer color, surely coreopsis is one of the most cheerful, free-flowering plants you can grow?

June planting gives tickseed enough time to settle in before it really goes into overdrive, which means its dainty, daisy-like blooms in yellow, gold, or bi-colors will create a constant haze of color through summer and often into autumn. It’s drought tolerant, low maintenance, and thrives in USDA zones 4-9. In mixed borders, it adds a lightness that balances heavier, structural plants, and in so many different styles, too.

Here are just a few of our favorite varieties...

4. Bee Balm

Bee balm, how do I love thee? Let me count the ways.

This pretty bloom feels almost theatrical in the garden, with its spiky, crown-like flowers in reds, pinks, and purples. It’s also one of the very best pollinator plants you can grow (its milkshake may not bring the boys to the yard, but its nectar has bees, butterflies, and hummingbirds all flocking).

It prefers slightly richer, moist soil, true, but rewards you with a long mid-to-late summer bloom period. And, hardy in USDA zones 3-9, it also brings a subtle minty fragrance when the leaves are brushed, which I’ve always loved on warm evenings in the garden. Something like the SUGAR BUZZ® Grape Gumball Bee Balm from Nature Hills promises purple prettiness right through to early fall.

5. Blanket Flower

Blanket flowers are pure fire energy in plant form, right? Their fiery red, orange, and yellow blooms feel almost sunset-like, and they thrive in conditions where other plants might struggle, making them ideal flowers to plant in June.

Once established, they’re extremely drought tolerant and will keep flowering steadily from summer through to frost if deadheaded. They perform best in USDA zones 3-10, making them one of the most adaptable late-season performers available.

There are several varieties available, but if you want something like the image above, you need the SpinTop® Orange Halo Blanket Flower from Nature Hills in your life, stat.

6. Shasta Daisy

With their crisp white petals and sunny yellow middles that seem to brighten even the dullest corner of a garden, shasta daisies always feel oddly nostalgic in the best possible way.

Planting them in June gives them more than enough time to establish before their peak flowering period in late summer, which means you get something that is excellent for cutting, reliable in borders, and thrive in USDA zones 4-9 just when you want it most.

Pick up the Whoops-A-Daisy Shasta Daisy from Nature Hills (the name alone, right? and try pairing with grasses and more structural perennials for a classic, slightly romantic feel.

7. Red Hot Poker

For a more dramatic late-summer statement, red hot pokers are unbeatable. The dwarf ‘Popsicle’ varieties (like the Red Hot Popsicle™ Dwarf Poker from Nature Hills) are particularly useful for smaller gardens, producing upright spikes of fiery red, orange, and yellow flowers that feel almost alien-like... in a good way, I promise.

They thrive in sunny, well-drained conditions and are hardy in USDA zones 5-9. In my experience, they’re the plants that make people stop and ask what they are – solely because they want to plant them for themselves, too.

Of course, there are a few other options if you want more flowers to plant in June for bold late-summer color that lasts into fall. You could try yarrow, for example, which more than earns its keep in any meadow-style display (although it does need deadheading to make it to autumn). And asters, obviously, bloom just as many summer flowers start to fade, extending the growing season far longer than seems feasible.

Whatever you choose, late-summer gardens are all about generosity, and these plants deliver exactly that. Planted in June, they don’t just fill space – they extend the season, support wildlife, and keep the garden feeling alive long after spring has faded. What could be better than that?
