Of three sorts

Sweet peas have no scent at all, or have a scent that's somewhat like cheap soap, or smell as wonderful as freesias. Some years we have no sweet peas before it's too hot; this year we have many sweet peas. For some reason, they're withstanding the heat very well, and the scent is truly delicious, very complex and very perceptible on the air. The color is a variegated, slightly mauve-tinged pink. Which sweet peas these are we have no idea.
