Definition and benefits

Perennial plants – which includes herbaceous perennials, shrubs and bushes – have a lifespan of more than two years. They last through winter, produce new shoots in spring, and delight us with their enduring presence. Sometimes the plant’s top growth dies back (as with herbaceous perennials) while the underground parts – the rootstock or rhizome – remain alive.

Giving a garden its long-term structure

Perennial plants are the backbone of any permanent garden design. From flowering herbaceous perennials to aromatic herbs and fruiting trees and bushes – they bring continuity, biodiversity and low maintenance costs.

Typical examples:

• Flowers: peony, daylily, cranesbill (hardy geranium) 
• Herbs: thyme, sage, oregano, chives
• Fruit etc.: rhubarb, strawberries, asparagus 
• Shrubs and bushes: lavender, raspberries, currants

✔️ They grow year after year – no replanting needed

✔️ Sustainable, economical, low maintenance

✔️ Habitat for beneficial insects and other creatures

Top tip: Combine perennials with annual flowering plants for a bed or border that’s full of life all year round.
