Thousands of begonias. Two replacements a year. Fifteen days to plant them. Five rounds of weeding. Then they are all pulled out, discarded, and the whole cycle starts again.
Seasonal municipal bedding — begonias, pansies, petunias, busy lizzies — is the most widely used and least efficient model of urban green decoration in British towns. Each cycle lasts three to four months. Each cycle requires: purchasing plants, transport, planting, irrigation, feeding, weeding, then complete removal and disposal of plant material. Two or three times a year. The cost in labour hours, water, fuel, organic waste, and plants that live a single season and leave nothing in the soil is significant.
Several British councils have started changing this. The approach is straightforward: replace seasonal bedding with hardy perennials. Same surface area. The same or better ornamental value. But with stable, lasting ground cover that does not need to die every three months to look maintained.
The advantages go beyond appearance. A well-designed perennial border:
— dramatically reduces annual labour (no seasonal replacement, less weeding, less irrigation once established)
— eliminates the cycle of plant waste removed and disposed of two to three times a year
— provides flowering and ground cover across a much longer season than any bedding scheme
— attracts pollinators and beneficial insects, integrating biodiversity into ordinary maintenance
— protects soil from erosion and compaction
Species that work in full sun in British conditions: lavender, Salvia nemorosa, catmint (Nepeta), yarrow (Achillea), Geranium 'Rozanne', Sedum (Hylotelephium spectabile), Echinacea, Perovskia. For shade: Geranium macrorrhizum, Waldsteinia, Heuchera, Liriope, Pachysandra — the same species already recommended for the bases of street trees.
The shift from annuals to perennials is not a compromise on aesthetics. It is a rejection of a model that spends public money producing disposable beauty. 🌿
A planting that does not need to die every three months to look cared for is not a neglected planting. It is a planting designed to last.
