Gardening is a lot of work… But It’s Worth It!
It’s true… But it is well worth it when you do a little research before you start to dig.
If you want your flower beds and garden to bloom for longer than a few weeks, you can’t just plant seeds without care and expect month-long results.
In fact, most perennials (perennial plants that don’t need to be replanted each year) have a shorter flowering season that can leave your garden looking a bit bare during the summer.
And after weeks of work, nothing is worse than looking at a garden lacking blooms!

There are so many long-blooming perennial plants to consider… This list is full of great choices for planning a garden for long-lasting blooms all summer long.
When designing your perennial flower garden consider the sun, water, and soil requirements of each plant.
Light Requirements
Not all perennial flowers that bloom all summer need the same amount of light. Equally, not every space is good for all perennials. Though many flowers tend to be forgiving you will want to consider the spaces you’re planning to put these plants in and how much sun they get throughout the day. A plant that prefers full sun is going to struggle in a heavily shaded spot and a plant that prefers shade will also struggle in full sun. Know if you have a shady garden or a sunny garden. It’s important to know how many hours of sun the spot you want to fill gets, so know how much space you have and what the lighting is like in those areas.
Soil Requirements
Consider the hardy zone you live in, and the soil conditions around your home before choosing flowering plants for your garden!
Some perennial flowers that bloom all summer can be fickle when it comes to their soil requirements. Not all flowering perennials have the same requirements. Some prefer well-drained soil while others prefer moist soil. Some tough plants actually thrive in poor soil while others are a bit more precious and will only grow in above-average soil.
