If you're looking to brighten up your outdoor space year-round without investing in new plants every season, keep reading to discover the best species, their characteristics, care, and expert recommendations.
What are perennials and why choose them?
Perennial plants are those that live for more than two years , often retaining their foliage throughout all seasons. They differ from annuals (which live for only one year) and biennials (which live for two seasons). Perennials include herbaceous, woody, shrubby, bulbous, and climbing varieties, making it possible to combine heights, textures, and colors in any garden or patio.
Main advantages of perennial plants:
- Long useful life: They do not need to be replanted every year, saving time and money.
- Variety of uses: They are used to cover walls, create flower beds, cover floors or give structure to the garden.
- Low maintenance: Many species are resistant to pests, droughts and frost.
- They add color all year round: Some have long blooms, others offer attractive leaves even in winter.
Choosing perennials suited to your space's climate, soil type, and sun exposure ensures lasting success and beauty without significant gardening efforts.
