Watering: Once a day, Water tray is recommended because N. Mirabilis need a lot of moisture specially in full sun. Make sure the water tray has a layer of water all the time.

Propagation: Stem Cutting, Seeds.

*It is theorized that because lowland species seeds find moist soil as soon as the seed is blown away from the seed capsule, that they need to be germinated as soon as possible.

Remarks:
Relatively easy to cultivate, it is sensitive to dryness specially if exposed in full sun. It will wilt if not given enough water, but will bounce back if given water in time. The leaves turn reddish in full sun.

Photos insitu shows that some Mirablis can be found in marsh area growing in soil that is submerged in water.

Just an update, had very hot and dry summer, Mirabilis was placed under shade cloth and the usual water tray, all Mirabilis did not show any problems, some even made basals and some had nice reddish leaves.

Suggestion is to not water the leaves during the heat of the day, instead make sure water tray has water in the morning and then just water at night to give cooling effect. I think Mirabilis does not need special attention during hot summers as long as their medium is kept moist, but not waterlogged.

I plant my N.mirabilis in a undrained pot and it's growing well ;) I leave 2cm of water in it every time I water
