Whether you're a busy gardener or just starting out, these ​​10 long-blooming perennials​​ deliver vibrant flowers all season while requiring little maintenance.

According to a 2023 Royal Horticultural Society (RHS) study, certain perennial varieties can flower for ​​12-16 weeks straight​​ when given proper care.
