A red summer frock

I like these little flowers when they open in the late afternoon.
In Spanish they are called don diegos, don pedros, periquitos.

Mirabilis jalapa is their name, but I have found many different names for them in the wikipedia:

In Indonesia it is called bunga pukul empat.
In China it is called the "shower flower" (Chinese: 洗澡花; pinyin: xǐzǎo huā) or "rice boiling flower" (simplified Chinese: 煮饭花; traditional Chinese: 煮飯花; pinyin: zhǔfàn huā) because it is in bloom at the time of these activities.
In Hong Kong it is known as "purple jasmine" (紫茉莉).
The Turkish name is akşam sefası, which means "evening pleasure".
In the Netherlands and in France the name of the plant is Nachtschone and belle de nuit respectively meaning "beauty of the night".
In Persian it is called laleh abbasi (لاله عباسی).
In Japan it is called oshiroi-bana, as the white, powdery endosperm inside of mature seeds looks like oshiroi, the powder foundation used by geishas.
In Hebrew it is called Lilanit Rav-Gonit (לילנית רב-גונית)- meaning "Queen of the night".
