The package from Burpee Seeds classified this sweet pea as “High Scent,” which immediately captured my attention and imagination as I stood in front of the racks of seeds in the garden centre in early spring. Sure enough, they didn’t falsify such a claim. These sweet peas smell like all the deeply delightful Lathyrus odoratus cultivars – whatever they were – of my childhood. I’m growing them out on the balcony and I keep stepping outside for a sniff. I may be a little obsessed.
