20 Luminous Perennial Flowers That Bloom All Season

If you plan on growing a flower garden, there is no better choice to fill your containers or raised beds than perennials - particularly if you want to take a more low-maintenance approach.

Perennials, unlike annuals, do not have to be replanted every year. Instead, you’ll enjoy recurring blooms each and every year, with very little work or hassle on your part.

The only downside to growing perennials is that some have very limited bloom times. They may only bloom for a few months - or even worse, a few weeks! - at a time.

If you’re looking for perennial flowers that bloom indefinitely, you’ve come to the right place. In this article, we will tell you about 20 perennial flowers that bloom all season for everlasting color.

20 Perennial Flowers That Bloom All Season

1. Pasque Flower

The pasque flower, or Pulsatilla vulgaris, is a beautiful flower with blooms that open in the early spring - sometimes when snow is still on the ground! Hardy in zones 4 to 8, this plant produces flowers that linger about three weeks each but will reappear all the way into the fall. It grows low to the ground, so it’s a good choice for a rock garden or as an edging plant.

2. Stella de Oro Daylily

There are several types of lilies that are known for their ability to produce color all season long, but the Stella de Oro daily is by far one of the most impressive.

This lovely flower is one of more than 50,000 hybrid daylilies that was created by crossing selected species within the genus.

It blooms for up to ten weeks, with each plant producing blossoms that open up at nine inches across. It is hardy in zones 4 to 9.

19. Catmint

Catmint is not the same thing as catnip, something that tends to confuse gardeners on their quest for long-lasting perennials.

Although both catmint and catnip are both forms of mint, they are different pieces and grown for different purposes. While catnip is grown for its effect on cats, catmint is prized for its landscape uses.

This plant grows up to a foot tall and is generally used as a ground cover. If you prune back the flower spikes after blooming, they will continue to put out new blossoms all season long.

Growing a Perennial Flower Garden That Blooms All Season Long

The trick to growing a perennial garden that remains colorful and beautiful all season long is to pick the right blooms. Choose plants that offer long-lasting color and that are appropriate for your specific growing conditions and growing zone.

Make sure you do some research about which plants are invasive, and research the blooming times for every plant you choose.

This can vary not just based on her pieces, but also based on the cultivars. For example, some clematis flowers the only flower in the spring, while others bloom on old growth in the fall.

Be sure to deadhead your plants, too. When plants flower, the goal is to produce seeds that they can reproduce.

By deadheading your plants, you will be encouraging second blooms. Some plants may require regular cutting back to encourage new blooms, too.

Finally, do your best to protect the flowers that you do have. When you experience harsh summer wind storms or heavy rains, your flowers can easily be damaged. This can discourage later flowering, too. Consider moving your potted plants inside when the weather turns, and do your best to cover up vulnerable plants.

Otherwise, growing a perennial garden with months-long color is definitely possible. It’s all about choosing the right plants - and considering this list of 20 perennial flowers that bloom all season long is a great place to start on your search for the perfect blooms!
