Vietnamese coriander/mint is not actually related to the mints, nor is it in the mint family Lamiaceae, but its general appearance and fragrance are reminiscent of them. Persicaria is in the family Polygonaceae, collectively known as “smartweeds” or “pink weeds”. A perennial plant that grows best in tropical and subtropical zones in warm and damp conditions. In advantageous conditions, it can grow up to 15–30 cm. Known as Vietnamese coriander, Vietnamese mint, Vietnamese cilantro, Cambodian mint, its leaves are used in Southeast Asian cooking.
An evergreen perennial that grows well in all climates, it does prefer a moist soil and likes full sun to part shade. Famously used in Singaporean laksa – and infamously used in Vietnamese herbal remedies to repress sexual urges – Vietnamese mint is also added to raw salads or Vietnamese spring rolls. The older the leaves the hotter the flavour, so try the younger leaves first before moving on to more mature ones. Vietnamese mint grows best in moist soil, pinch it back regularly to encourage fresh bushy growth. If left to its own devices, Vietnamese mint can before tall and leggy. Apply a liquid fertiliser once a month during spring and summer.
Feeding: apply a seaweed solution at planting. In frost-prone areas, also apply a seaweed solution periodically from late autumn through winter to improve frost tolerance.
Watering: regular watering is required, especially during hot or dry weather.
