Perennials are appealing for most gardeners because they return every year, meaning that you don’t have to spend hours hunched over your garden beds digging, fertilizing, and watering new plants. However, the one downside to perennials is that some have shorter blooming times than even annuals do. Choosing long blooming perennials for your garden ensures that your home is surrounded by color each growing season.
There are more long blooming perennials than you probably think. In fact, there are plenty of blooms lasting longer than six weeks.
Taking the time to make sure your perennials become established pays off in the long run. One season of labor is worth the work because, after that, they require little effort and provide you with lush greenery for years and years.

Getting the Most Out of Your Garden
Every successful garden provides visual interest throughout each season, starting in the early spring with new colors emerging through the late fall and sometimes even into the winter.
While you can and should plant some long flowering annuals, long blooming perennials are low-maintenance plants with all the requirements for designing flower beds with constant scenery. With a little planning, it’s possible to extend your plants’ bloom time even longer.
When choosing plants to grow in your flower beds, long blooming perennials should be your go-to. While flowers with shorter bloom times and annuals are fine, picking plants that last for years makes gardening simpler.
Deadheading your flowers the moment they begin to die off also prolongs the bloom time. Simply pinch or cut the stem below the flower head and above the first set of healthy leaves.
Giving your long blooming perennials fertilizer provides them with proper nutrition throughout the year to help them live a long, healthy life.
Finally, visit your local garden center multiple times throughout the year. You’d be surprised how different plants look during different seasons.
