In Malaysia, Turnera subulata grows wild like a weed in open fields and sunny areas.
This native of Tropical America is very much at home in our equatorial climate.
The flowers open at about 8 O'clock in the morning and close before noon.
Some people plant it in their garden. It is also often planted in front of entrances to buildings and homes. I think it is better to plant it outside your homes because Turnera subulata attracts lots of wildlife. Just look at my pictures below. Bees may sting young children.
