A flower to leave daughter. Expected time of arrival, about one (7)
I believe the answer is:
godetia
'a flower to leave daughter expected time of arrival about one' is the definition.
I can't tell whether this definition defines the answer.
'flower to leave daughter expected time of arrival about one' is the wordplay.
'flower' indicates anagramming the letters (I've seen 'flowering' mean this (letters develop or 'flower' into another form)).
'leave' says to take the initial letters (I've seen 'left of' mean this (the leftmost letter in the word)).
'time of arrival' becomes 'gi' (I am not sure about this - if you are sure you should believe this answer much more).
'about' means one lot of letters goes inside another.
'one' becomes 'a' (a thing is one thing).
The initial letters of 'daughter expected' is 'de'.
'to'+'de'='tode'
'tode' is an anagram of 'odet'.
'odet' placed inside 'gi' is 'godeti'.
'godeti'+'a'='GODETIA'
Can you help me to learn more?
(Other definitions for godetia that I've seen before include "Garden flower" , "Showy plant, I'd go eat (anag.)" , "Showy plant; got idea (anag.)" .)
