Tiny spring flower (9)
I believe the answer is:
streamlet

'tiny spring' is the first definition.
The definition and answer can be both natural objects as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'flower' is the second definition.

Can you help me to learn more?
(Other definitions for streamlet that I've seen before include "running water" , "hardly a river" , "Burn" , "small brook" .)
