Perennial flowers are most preferred for their ability to come back year after year. They bloom in the spring and summer months and are dormant in the winter season. This is possible due to their roots that go deeper into the soil, increasing their lifespan.
Different perennials adapt individually to different climates. Some will thrive in dry conditions while others prefer a cold environment.
