Our national flower, the Bunga Raya, represents courage, political and economic strength, among other things. Elaine Yim writes

TOMORROW we celebrate our 57th Merdeka. Let’s appreciate the beauty of our national flower, the hibiscus, and find out more about the plants from the hibiscus family Malvaceae.

Malvaceae includes more than 200 genera and 4,000 species of flowering trees and shrubs, some of which are of economic importance, such as cotton and cocoa. It also includes plants as diverse as the kapok, baobab and durian.

OUR NATIONAL FLOWER

Hibiscus rosa-sinensis is the national flower of our country. Our first Prime Minister, Tunku Abdul Rahman Putra Al-Haj, selected this species, also known as the “common hibiscus” because it grows abundantly here.

The red colour represents courage, political and economic strength, while the five petals denote the five principles of Rukun Negara. The many different varieties and cultivars of the hibiscus represent the rich, multi-ethnic multi-cultural background of our people.

The Malay name for hibiscus is “bunga raya”, which means flower of celebration.

There are countless varieties of hibiscus rosa-sinensis plants and we are spoilt for choice. The flowers can be single or double, big or small, in many different colours, shades and colour combinations. Many new hybrids and cultivars are being produced by the horticulture industry regularly, so look out for them when you go flower hunting at the nurseries.

The double flower varieties are gorgeous. They look like roses without thorns.

HOW TO GROW

Most varieties can be grown under a full sun and easily propagated by cuttings. The Hawaiian cultivars, meanwhile, prefer some shade, are heavy feeders and their flower buds may abort easily. But don’t despair. Do continue to experiment with what you like. After all, beauty is transient so enjoy the moment while it lasts!

Hibiscus rosa-sinensis flowers lasts only a day. They are edible and attract sunbirds and butterflies.

Hibiscus plants need rich, moist, well-drained soil, regular watering and full sun to partial shade. Propagation is by cuttings unless otherwise stated.

EDIBLE FLOWERS

The petals of this flower can be eaten raw. After you pluck the flowers, separate the petals from the flower stalk. Try sucking the sweet nectar from the base. Remove the pistils and use the petals to garnish salads or steep the petals in hot water to make a purple-coloured drink. When a few drops of lime juice are added, it will turn a brilliant red colour. Add some honey or sugar for taste and some ice cubes.
