Sentimental girl invited to see garden left home (7)

I haven't cracked this one yet — but the brilliant team at Times for the Times have:

MAUD (girl invited to see garden), L (left), IN (home). Tennyson’s poem Maud begins: Come into the garden, Maud. It used to be widely known but is now probably unfamiliar to most under a certain age. It was also set to music as a popular song performed by Marie Lloyd. Quickie solvers may have had an advantage here as the poem was referenced in a clue set by Izetti last November.
