Conventional grass in a park or public garden comes with costs that are rarely apparent: constant watering, weekly mowing, periodic fertilization, and virtually no biodiversity. It is an expensive solution to maintain and one that is increasingly difficult to justify in the context of growing water stress and high labor costs.
Natural grasslands and vegetation cover composed of native flora are the technical alternative to that model: less water, less maintenance, and much more life and health for everyone.
In this article, we explain what they are, what benefits they offer compared to conventional grass and traditional landscaping, and how they are used to restore parks, tree pits, and other urban or suburban green spaces to their natural state.
The Problem with Conventional Lawns in the City
Most urban lawns are based on species such as Festuca arundinacea or Lolium perenne, which in many cases are not adapted to the extreme Mediterranean climate. The result:
- Intensive irrigation for much of the year, which is incompatible with the increasingly common water restrictions
- Very frequent mowing, with the associated maintenance costs and emissions
- Fertilization and regular treatments to maintain color, density, and plant health.
- Virtually no biodiversity—a monoculture that neither attracts nor provides resources to pollinators or beneficial wildlife
What Is a Natural Grassland?
A natural meadow is a mixture of grasses and herbaceous plants, including wildflowers, all of which are native to the area, designed to sustain itself through spontaneous reseeding, without the need for irrigation or fertilization once established. It does not aim for the uniform appearance of a lawn, but rather a living ground cover that changes with the seasons (shifting from shades of green to ochre, with different blooms and colors throughout this transition).
Benefits of Natural Grasslands and Native Green Roofs
Water Conservation and Maintenance
Once established, a natural meadow sustains itself with the area's rainfall and requires, at most, one or two mowings a year—as opposed to the weekly watering and mowing of a conventional lawn.
Actual functional biodiversity
Native flower species have ecological relationships with pollinators and other wildlife in the area—something that a monospecific lawn cannot provide.
Seasonal scenic value
Unlike a lawn, which is meant to look uniform all year round, a natural meadow changes in color and texture with the seasons—spring blooms, golden hues in summer, and regrowth in the fall.
Thermal Regulation in the Urban Environment
Vegetation cover reduces the surface temperature compared to asphalt or bare soil, helping to mitigate the urban heat island effect.
Compliance with Urban Biodiversity Regulations
More and more city councils are incorporating requirements for biodiversity and the sustainable management of urban green spaces into their specifications and ordinances. Native grasslands and vegetation are one of the most direct ways to meet these requirements.
Natural Health for Everyone
This service is increasingly valued by the public, as its implementation helps attract beneficial insects, birds, and small mammals that control pests and diseases. It also provides a sense of being close to nature.
Applications in Urban Settings
Natural grasslands in parks and large green spaces
The most straightforward application: replacing low-traffic lawn areas with low-maintenance flower meadows, reserving traditional lawns only for high-traffic areas such as sports fields.
Tree pits and landscaping along public roads
Tree pits are confined spaces with challenging conditions (soil compaction, partial shade from buildings, shallow soil depth). Mixtures of herbaceous plants and small- to medium-sized wildflowers are perfectly suited to these conditions, creating spaces that offer unique biodiversity and natural beauty.
Vegetation cover and green roofs
In bioclimatic architecture, green roofs require low-growing species with shallow root systems and high tolerance to sunlight and drought. The native Mediterranean flora of poor soils—thyme, low-growing grasses, and native succulents—is, by nature, the best candidate for this purpose.
Recommended Species
Dwarf grasses
- Poa pratensis — groundcover, highly resistant to drought and occasional trampling
- Sheep fescue — a low-maintenance perennial, suitable for poor soil
Flowering herbaceous plants
- Papaver rhoeas — poppy, a very showy spring flower
- Centaurea spp. — cornflower, with a long blooming season and highly attractive to pollinators
- Bellis perennis — wild daisy, an early-blooming groundcover
Groundcover Herbs
- Thymus spp. — thyme, which is well-suited for green roofs due to its compact size and hardiness
- Santolina chamaecyparissus — shepherd's chamomile, silvery and compact, ideal for tree pits
Real-world examples: where it's already in use
CANTUESO is a supplier to the Barcelona City Council for urban landscaping projects featuring native plants, and our low-maintenance seed mixtures are used in many municipalities throughout Spain. These examples show that natural grasslands are not just a theoretical alternative: they work in public and heavily used spaces, with proven results.
How to Start a Natural Meadow or Green Roof Project
1. Analyze the space. Area, orientation, soil type, intended use, and level of maintenance available.
2. Design the mixture. The composition must be tailored to the climate zone and the intended use—there is no one-size-fits-all mixture.
3. Plant in the fall. The best time is from October to December, when the first rains begin.
4. Minimal maintenance during the first year. Occasional supplemental watering may be necessary during the first summer; starting in the second year, the system is self-sustaining.
CANTUESO NATURALIZA
At CANTUESO, we design seed mixtures of native species for natural meadows, tree pits, and green roofs tailored to each urban landscaping project. We advise city governments, landscaping firms, and architects on species selection and compliance with urban biodiversity requirements.
