No, pandan and lemongrass are 2 different types of plants. Lemongrass is a green plant with long, thin, blade like leaves that can grow up to 60 cm to 70 cm long. The long leaves are not used in cooking, but rather the bulb right above its roots. The first few outer layers of the bulb are peeled off and discarded to obtain the useable part of the lemongrass plant. It is often used for its strong and pleasant citrusy fragrance. Pandan (known as screwpine in English) is also a green plant with long, blade like leaves, but pandan leaves are wider and darker green in color. The leaves can also grow up to 60cm long and the entire leaves can be used in cooking. Similar to lemongrass, pandan is often added into food for its lovely fragrance and in some dishes, the extract from the leaves is used as a natural green colorant.
