The Garden City is in full bloom from now until next month and it has the recent rain showers to thank for that.
Mr Oh Cheow Sheng, National Parks Board's group director of streetscape, says the wet weather has "contributed to the flowering of these plants".
Singapore has more than 2,000 native species and the previous flowering season, also because of a wet spell, was earlier this year in March and April. Although the next two weeks are reported to be drier and warmer than last month, some thundery showers are still expected.
Nature photographers are advised to grab the earliest opportunity to snap these blooms as heavy rains can shorten the blooming season.
Mr Oh shares where to find the flowers.
Oleander (Nerium oleander) and varieties of bougainvillea
What: Oleanders are small green shrubs with pretty purple flowers while bougainvilleas come in a wider range of colours such as white, yellow-orange, purple and pink.
Where: Bougainvilleas are commonly found around the island, especially on overhead bridges.
A fun way to see both flowers would be to rent a bicycle with friends and family and ride around East Coast Park.
Trumpet Tree (Tabebuia rosea)

Where: Along the Ayer Rajah Expressway near Hong Leong Garden; or Central Expressway near Cambridge Road and the Moulmein Road exit
Handkerchief Tree (Maniltoa browneoides)
What: Its blooms are hard to miss - big, drooping pale-yellow flowers that resemble handkerchiefs.
Where: Yishun Avenue 2; University Road off Dunearn Road; Martin Road in River Valley; Punggol Walk; and Sengkang Square
Cat's Claw Ivy (Macfadyena unguis-cati)
