I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">biblical garden</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for eden that I've seen before include "at Number Ten once?" , "Biblical garden" , "Unspoiled paradise" , "Paradise - ex-prime minister" , "Place of unspoiled beauty" .)
