Oct means the smell of kinmokusei

kinmokusei (キンモクセイ／金木犀) (Eng: Osmanthus fragrans a.k.a. Sweet Olive, Tea Olive and Fragrant Olive)

There is one of those trees in our backyard. At the end of summer it releases a subtle first scent one can detect with a keen sense of smell. Increasingly the subtleness is replaced by a sure but elegant aroma. It fills the chilled air with signs of fall, a constant and steady flow of nature's perfume.
