Context:

CHAPTER 19 DAWN AND DUSK In early June , when the sand hills were a great glory of pink wild roses , and the Glen was smothered in apple blossoms , Marilla arrived at the little house , accompanied by a black horsehair trunk , patterned with brass nails , which had reposed undisturbed in the Green Gables garret for half a century .

Hypothesis: Green Gables was green year round.
