Lathyrus chloranthus is a seldom-seen species of sweet pea in a color you don’t expect: some blooms are clear yellow and others develop orange shading. The 2020 growing season was the first time I tried this beauty in my garden. I didn’t expect much from it and was pleasantly surprised by its performance: the seeds produced good-looking, vigorous vines with abundant, light green to grayish green foliage, and flowers appeared from early summer into early September.
Don’t expect a traffic-stopping bloom display–the flowers are on the small side–and unlike more commonly grown sweet peas, this one does not have any fragrance. It’s still worth growing for its rarity and its uncommon color. My vines reached 4 to 5 feet tall, so a large support isn’t necessary. In fact, I think this species would look great on a tripod of stakes in a medium-sized to large container, where the blooms would be closer to eye level. Full sun (in cooler areas, at least; my plants did well with shade during the hottest part of the day). Annual.
Harvested in August, September, and October 2020. At least 10 seeds.
