1,200 metres above sea-level, surrounded by grasslands and between rich conifer and mixed forests, the gardener Jorge Giusto cultivates his own pharmacist garden in the Córdoba region at the heart of Argentina. This Weleda garden has not been planned out with neat beds and plots. Instead, medicinal plants such as primula, echinacea, berberis and fern flourish casually in the existing wild landscape. Old trees provide shade during the hot summer months, and a stream winds through 12 acres of burgeoning gardens. About 70 medicinal plants species are cultivated here and the harvest is processed into medicines by Jorge’s own pharmacy, to the east in Buenos Aires.
