Yu Qingxue wouldn't have spent the money to add it, but when she bought her new home it was already in place. She wasn't that into gardening, but the previous owner had kept a very large flower garden on the spacious grounds and had a large, glass enclosure attached to the back of the house alongside the deck where she raised prize-winning violets.
It wasn't really glass. The clear, curved panels of its roof and the not-so-clear panels of its walls were actually some sort of heavy plastic. It faced south so the full force of the sun shone on it throughout the day. The description of the home on the realtor's website said it had an attached greenhouse, but as the realtor showed Yu Qingxue around the place, she constantly referred to it as a hothouse.
