Roman gardens

• 1. Introduction

  ›

  Roman gardens reached their peak between 150 BC and 350 AD, shaping how people across Europe and beyond thought about green space, beauty, and the boundary between indoors and outdoors. The Gardens of Lucullus, known in Latin as the Horti Lucullani, sat on the Pincian Hill in Rome and brought the Persian garden tradition to European soil around 60 BC. For Romans who knew them, these grounds were not just places of beauty. They were refuges from the noise of city life, spaces thick with religious meaning, and a demonstration of how far Roman civilization had traveled in its tastes and ambitions.

  But Roman gardens were not only for the powerful. Excavations at Pompeii have shown that ordinary Romans scaled gardens down to fit the constraints of their homes, planting roses and cypress and herbs in whatever space they had. Cato the Elder, writing in his text De agri cultura, argued that every garden should sit close to the house and include flower beds and ornamental trees. That advice tells us something important: the garden was not a luxury reserved for the wealthy. It was part of Roman life from the kitchen plot to the imperial pleasure ground.

  How did the Romans develop these ideas? Where did their techniques come from, and what happened to that knowledge after the empire faded? The answer runs through ancient Persia, Ptolemaic Egypt, and the gardens of Athens, and it ends in the hands of Renaissance and Baroque landscape architects who never stopped borrowing from Rome.

  Formal gardens existed in Egypt as early as 2800 BC. By the time of the 18th dynasty of Egypt, the techniques used to beautify wealthy homes were already fully mature. Egyptian builders connected houses to outdoor living spaces through porticos, the covered porches that would become a defining feature of Roman domestic design.

  Persian gardening developed its own logic in response to a very different landscape. The arid climate of Persia demanded enclosed gardens, built to trap winter warmth, shield plants from drying winds, and stand in deliberate contrast to the barren terrain outside the walls. Designers organized these spaces around rills, the narrow water channels known from the site of Pasargadae. When Alexander the Great pushed through Western Asia, he brought back new varieties of fruits and plants that sparked a renewed enthusiasm for horticulture across the ancient world.

  The Greek contribution was both direct and indirect. Even before Alexander, Cimon of Athens reportedly tore down the walls of his own garden to open it to the public. Scholars believe the Romans learned the rill technique from the Greeks rather than from Persia directly, though archaeological evidence of rills in classical Greek gardens has not yet been found. Greek pleasure gardens also grew fruit and maintained sacred groves in honor of the gods, but the domestic peristyle garden, the open courtyard surrounded by columns, was adopted and developed most fully in Rome. Cities like Sparta, Corinth, and Patras took up the Western peristyle domestic style; Athens itself did not.

• 3. A Garden for Every Roman

  Lower-class Romans started with kitchen gardens, growing herbs and vegetables to feed their families. In Ancient Latium, a garden was simply part of every farm. The shift toward pleasure gardens came as Roman culture absorbed Egyptian, Persian, and Greek influences, producing not just villa gardens for the wealthy but public parks and spaces meant for exercise and enjoyment.

  Augustus constructed the Porticus Liviae, a public garden on the Oppian Hill in Rome, making the garden an instrument of public life as well as private pleasure. Outside Rome, gardens proliferated at centers of wealth, and modified versions of Roman garden design were adopted in Roman settlements across Africa, Gaul, and Britannia.

  No type of garden was exclusively restricted to wealthy Romans. All a person needed was their own land or home. Pompeii's excavations make this concrete: gardens attached to ordinary residences were simply smaller, adjusted to fit the space available. Horace wrote that flower gardens had become a national indulgence during his own lifetime, suggesting that the appetite for gardens had spread well beyond the aristocratic estates where it began.

  Pleasure gardens followed a recognizable structure regardless of their scale. A patio at the entrance held outdoor furniture and a water basin or fountain, and served as the starting point of a walk designed to show off the garden's features. From there, a visitor would move through terraces, orchards or vineyards, kitchen plots, pergolas, and shrines.

  The xystus, a garden walk or terrace, was a core element. It typically overlooked a lower garden area called the ambulation, which was bordered by flowers, trees, and foliage and was designed as a place for a stroll after a meal or conversation. The gestation was a shaded avenue where the owner of the house might ride horseback or be carried, generally encircling the ambulation or laid out as a separate oval-shaped space.

  Walls were not merely boundaries. They carried aesthetic weight, decorated with statues, paintings, and design elements. Practical gardens embedded fragments of pottery into the perimeter walls to deter theft and vandalism. Wilhelmina Jashemski excavated one such shop garden at Pompeii and found exactly this kind of fortified boundary. Even the atrium inside the house was considered part of the garden because its opening allowed Romans to collect rainwater in a basin called an impluvium. The line between architecture and garden was deliberately blurred.

  Terrace gardens solved the problem of hilly terrain by creating stepped levels, often designed to contrast one another. Peristyle courts, the colonnaded open courtyards whose name comes from the Greek for "around" and "column," connected homes to the outdoors and provided a sheltered but open-air room at the heart of the house.

  Pine trees, roses, cypress, rosemary, and mulberry trees were among the most popular plants in a typical Roman family's garden. Dwarf trees were pruned for ornamental effect. Marigolds, hyacinths, narcissi, violets, saffron, cassia, and thyme were also cultivated. Planting followed a practical logic: smaller plants toward the front of the bed, larger ones at the back.

  Rose, violet, geranium, and buttercup pollen samples have been recovered from garden sites. Lilies, irises, and daisies appear prominently in garden frescoes. Large-scale commercial flower gardens have been excavated as well, among them the Garden of Hercules at Pompeii. Flowers and plants like parsley were grown both for appearance and for use in perfume and ceremonial garlands.

  Herbs such as garlic, basil, coriander, dill, parsley, rosemary, onion, and mustard were cultivated for the kitchen and for medicine, spread across the Empire as far as Britain. Vining plants were trained up garden structures for shade and decoration, and grapes were woven throughout gardens. A villa rustica might include equipment to process those grapes into wine.

  Pliny the Elder, writing in the Natural History, noted that certain trees were planted in honor of specific gods, giving the garden a religious dimension that was never entirely separate from the aesthetic one. Villa Boscoreale in Herculaneum, where extensive pollen analysis has been conducted, offers one of the most detailed windows into which species the Romans actually cultivated at a large agricultural estate.

• 6. From Rome to Renaissance

  ›

  Roman garden practices traveled with the empire itself, influencing and being influenced by the territories Rome absorbed. Designers adapted the basic forms to local climates as the empire expanded. After Rome, much of this knowledge passed through the gardening traditions of the Byzantine Empire, which preserved and transmitted the core ideas.

  That inheritance shaped the Italian garden, which became the template for Renaissance, Baroque, Neoclassical, and even twentieth-century landscape architects. The continuity is visible in contemporary Italian practice: modern Italian gardens still feature the interplanting of various species and the use of terracotta pots, both hallmarks of the Roman approach.

  The tools used to understand Roman gardens are as varied as the gardens themselves. Archaeological and archaeobotanical research, most famously at Pompeii, has been combined with literary sources, wall paintings, and mosaics to reconstruct what grew where and why. The maritime villa at Laurentum, described at length by Pliny the Younger in his letters, provides one of the most detailed written portraits of how a wealthy Roman conceived of garden space, including private areas for exercise and open grounds for hunting game.
