6 Flowers to Grow in June for Blooms by August – It's Not Too Late For a Summer of Color
Add these plants to your garden now for a vibrant late-season display
If you had a busy spring and didn't get around to as much planting as you were hoping to, don't fret. It's not too late to plant several seeds and starter plants in June to get a colorful display by August.
The trick is choosing fast-growing plants for your flower bed, as well as starter plants that have already started growing at a nursery (like these live marigold plants from Amazon). Getting them in the ground now means there's still time for seeds to sprout and roots to settle for flowering in August. In fact, now that early summer is here, you can direct sow many seeds and don't have to worry about transplanting.
Of course, it is important to choose the right plants to be successful, as you don't want to waste time on any that take a long time to grow and won't have time to bloom before the end of summer. Here, I talk trough six reliable options to choose.
Cosmos
While it's most typical to grow cosmos by starting them indoors early and planting out in spring, you can still plant cosmos this month for summer flowers.
You can direct sow seeds outdoors where they will sprout quickly in the warm soil. Make sure to just scatter the seeds on the surface and gently press them in, as they need light to germinate.
Alternatively, you can plant out seedlings and plug plants from a nursery. Choose a direct sun position and ensure soil is well-draining and nutrient rich, without being too nitrogen-heavy which will encourage leafy growth over blooms.

This cosmos blend has white, pink, rose, and crimson blooms. These fast-growing annuals can reach 1-6ft in height and make beautiful cut flowers.

Zinnias
Another fast-growing annual you can sow in June for blooms in just eight weeks is zinnia.
Zinnias are some of the most joyful blooms, coming in a wide range of colors from red and orange, to pink and yellow. They're incredibly easy and rewarding to grow.
You can also purchase zinnia starter plants which will already have stems, ready to bloom shortly. Just don't forget to pinch out zinnias to encourage branching, which will give you even more stems to cut for vases.

Sunflowers
You can grow sunflowers from seed exceptionally quickly, especially once the soil is warm in early summer.
Sunflowers have deep taproots and don't like being transplanted, so it is best to direct sow them this month. You can also opt for dwarf varieties to grow sunflowers in a pot.
Just take care to keep sunflowers consistently watered, especially during hot spells in summer, otherwise they will droop and wilt.

Ammi needs well-draining soil and consistent moisture. You may find the tallest stems (which can reach 3-5ft tall) need staking as they can become top-heavy.
