Plant as present found in small delivery (8)
I believe the answer is:
snowdrop
'plant' is the definition.
(a snowdrop is a plant)
'present found in small delivery' is the wordplay.
'present' becomes 'now' (both can mean the current period).
'found in' is an insertion indicator.
'small' becomes 's' (abbreviation - e.g. clothes size).
'delivery' becomes 'drop' (I've seen this before).
's'+'drop'='sdrop'
'now' inserted into 'sdrop' is 'SNOWDROP'.
'as' is the link.
(Other definitions for snowdrop that I've seen before include "covering borders in spring" , "Late winter flower" , "Rows pond (anag)" , "Small white flower of early spring" , "White-flowered plant (Galanthus nivalis)" .)
