Jardín de Cactus

Plants in a quarry

The garden occupies a quarry once worked for volcanic lapilli, the granular material also known locally as picón or rofe. Farmers spread it over cultivated ground to help retain moisture. Rather than conceal that excavated setting, Manrique used its amphitheatre-like form to organise the garden, with plants arranged across terraces. The result is a collection seen both close up and as a planted bowl. Botanist Estanislao González Ferrer was responsible for selecting and planting the specimens, giving the project a botanical foundation alongside its architectural design. There are now 4,500 examples of 450 species of cacti and succulents, drawn from desert and other arid regions. A visit centres on looking through that collection and seeing how individual plants relate to the terraced arrangement. Unlike Mirador del Río, which frames distant islands through broad windows, Jardín de Cactus keeps the main view within the site itself: quarry, planting and windmill make up the composition.

The windmill and local crops

A restored windmill stands at the garden's highest point, above the planted terraces. It was once used in the production of gofio, so it connects the garden to food production as well as providing a recognisable feature above the quarry. The surrounding area has another agricultural connection: prickly pears are cultivated for cochineal. This insect is the source of carmine, a natural dye, and explains why cactus cultivation here has a purpose beyond ornamental planting. Together, the quarry, windmill and prickly pears give the garden a setting rooted in local working practices. The quarry supplied material for retaining moisture in cultivated land; the mill served food production; the surrounding crop supported dye-making. Manrique's 1991 project placed a botanical collection within that context rather than starting on an unrelated plot. For visitors, the windmill is the feature to look for above the amphitheatre, while the planted terraces below show the scale of the cactus and succulent collection.

Manrique and the planting

Jardín de Cactus was created in 1991 and was César Manrique's last project. Its design combines an existing excavated space with a botanical collection, rather than treating the plants and the surrounding architecture as unrelated attractions. Manrique shaped the garden around the former quarry's amphitheatre form, while botanist Estanislao González Ferrer selected and planted the specimens. That division of work matters to what a visitor sees: the terraces organise the overall view, but the collection has a breadth that extends beyond its visual arrangement. The garden now contains 4,500 examples of 450 cactus and succulent species from desert and other arid areas. The restored windmill marks the highest point above the planting and helps make the layout legible as a whole. Looking across the quarry reveals the terraced composition; looking through the planting brings attention back to individual specimens. Both scales are central to the garden, which is neither simply a preserved quarry nor a collection placed on flat ground.

Choosing between Manrique sites

Jardín de Cactus suits a visit focused on planting and the reuse of a worked landscape. The main subjects stay close together: the former quarry, terraced collection and restored windmill form the garden's central arrangement. Mirador del Río offers a contrasting experience. There, a stone-covered building opens towards the Strait of El Río and La Graciosa, making the distant outlook central to the visit. At Jardín de Cactus, the interest is contained within the amphitheatre, so the individual specimens and their position on the terraces deserve attention alongside the overall shape. The site's agricultural background also distinguishes it. Volcanic lapilli was extracted here to help retain moisture on cultivated land, and prickly pears in the surrounding area are grown for cochineal dye production. Those uses give context to the transformation into a garden. It is a place to examine a planted collection within Manrique's design, rather than a viewpoint whose main subject lies beyond its boundaries.

What to look for

• Look across the amphitheatre-shaped quarry and its planted terraces
• Explore a collection of 450 cactus and succulent species
• See the restored windmill above the highest terraces
• Look for the relationship between quarry walls and planting
• Compare individual specimens with the arrangement of the whole garden
• See how a former extraction site became a terraced botanical collection
