June is one of the months that ushers in the season of perennial flowers. It’s the time when colorful flowers fill up gardens.

Perennial flowers range from medium and small shrub-like sized plants to larger ones. One clear thing about these perennial flowers is that they bloom and stay colorful. They also need substantial sunlight exposure.

Either way, they stand out and are also easy to grow. Usually, they can grow both from seedlings and seeds to fully bloomed plants. Below are some of the best perennial flowers to consider this summer season.

Make sure to deadhead the flowers at least once to help boost blooming. Remember that this plant takes about two years to bloom fully when grown from the seed level. Therefore, if you want an immediate bloom this season, consider getting seedlings from a nursery or a different gardener.

2. Balloon Flower

The balloon flower is a standard-sized perennial flower. It goes by the scientific name Platycodon grandiflorus. Its size ranges from 12-20 inches and has a plant zone of 3-8. The plant also requires partial shade with a full sun exposure combination

Usually, before they open, they resemble a full balloon filled with air; when they open up, the flowers resemble bell-shaped stars.

The balloon flowers are perfect when planted along borders. They work well when combined with other low-growing perennials. Be sure to stake the taller plants since they tend to be heavier when fully blooming. Interestingly, these flowers can blossom in the first year when grown from seeds.

However, this depends on the location and climate of the area they are grown.

4. Coneflower

Once the plant’s first bloom elapses and fades away, cutting back at least by one-third is best. Doing this promotes the second bloom after the first growth from seeds. The second bloom will then bloom and develop flowers in Fall.

Coreopsis will take about 60 days to blossom after it has been planted from the seed. You can still enjoy the plants’ bloom in the season. It doesn’t matter if you sow them from seed or use starter plants.
