Indonesian bay leaf often used in cooking

This plant started growing outside my house. I want to remove it, but it is healthy. What is it and how big will it grow?

The plant is likely the Indonesian bay leaf or Salam, and is botanically known as Syzygium polyanthum. Its fruit is popular with birds, which disperse the seeds through their droppings.

In South-east Asia, in particular Indonesia, the young leaves are often used as a spice in cooking. Fresh or dried leaves are added to meat and vegetable curries, rice and stews.

Over time, the sapling will grow into a tree. The space it has nowwill restrict its growth in the future.

Tip: Arrowroot folds its leaves in dark surrounding

The variegated version (pictured) of the arrowroot plant has showy leaves, which feature white bands against a green background. This plant is known botanically as Maranta arundinacea.

The arrowroot produces swollen roots - they are rich in starch that is easily digestible. It is extracted and used in foods such as infant formulas and confectioneries.

The plant - part of the Prayer Plant family - has a curious habit of folding its leaves when the environment is dark. It needs a sunny spot and moist, well-drained soil to thrive.

This climber is probably the Giant Dutchman's Pipe. Its botanical name is Aristolochia gigantea. As it is a large climber, it needs a sturdy and tall trellis.

This ornamental plant also needs a sunny spot to thrive. The soil should be moisture-retentive, fertile and well-drained. The plant can be propagated by seeds or stem-cuttings.

It is not widely available, but can be bought at large plant nurseries such as Hua Hng Trading Co in Bah Soon Pah Road. Call the nursery to check before making your way there.
