In Malaysia or Singapore it is commonly known as daun kesom. Vietnamese called it rau ram. In Australia you find it in asian grocery shop labelled as Laksa leaf, named after the popular dish Laksa. The one I grown last year from stems died during winter. So now as it gets warmer here , we propagated new ones from Laksa leaf bought from Asian grocery shop that has been kept in the fridge shelves! Choose the one which are young stems and pick the leaves (use them for cooking) leaving the young ones only. Stick the young stem in soil. Then watch them grow with no need of pampering at all.
After 10 days…more leaves develop.Easy to grow. No need to buy a whole plant in nursery. Propagating own Laksa leaf from separate stems will have many plants to grow and still leaving lots of leaves for cooking.
