The National Parks Board (NParks) is opening the Pasir Panjang Nursery, its only nursery, to the public for a rare guided tour this weekend.
The nursery tour is organised in conjunction with the year-long Clean and Green Singapore 2015 campaign, which aims to inspire Singaporeans to protect the environment.
The Pasir Panjang Nursery is about 12ha, or the size of 30 football fields, and supplies close to 200,000 plants each year to green the island's roads and parks.
Most of the plants provided by the nursery are native to Singapore and are not easily available in commercial nurseries.
It also sources for plants from countries such as Malaysia, Indonesia and Thailand to increase the variety of plants used in NParks' planting programmes.
The nursery's inventory includes trees, shrubs, herbs, fruit trees, aquatic plants and more.
To support the conservation of Singapore's native species, NParks officers also collect seeds and saplings of native plants from forests and parks across Singapore every week, so they can be grown in the nursery until they are ready to be planted islandwide.
NParks chief executive Kenneth Er said the nursery is a key part in Singapore's greening efforts.
"Decades of our pioneers' hard work... have enabled us to reap the benefits of the verdant landscape.
"(The tour) is one way of inspiring the community to continue in the shared responsibility of carrying on Singapore's greening journey," he said.
The NParks website says all 200 places for this Saturday's tour have been snapped up.
The new public tour is free but prior registration is required. Registration is based on a first-come-first-served basis.
