Congreve's initial opening scenes: they are naturally juicy! (5)

Ross

I believe the answer is:

cacti

I'm a little stuck... Click here to teach me more about this clue!

'they are naturally juicy' is the definition.
The definition suggests an adverb but the answer is not.

'congreve's initial opening scenes' is the wordplay.
'initial' suggests taking the first letters.
'opening scenes' becomes 'acti' (I've seen this in another clue).
The initial letter of 'congreve' is 'c'.
'c'+'acti'='CACTI'

Can you help me to learn more?

(Other definitions for cacti that I've seen before include "Prickly Pears perhaps" , "Spiny desert plants" , "Spiny succulents" , "Tunas" , "Prickly types" .)
