Sweet Pea ‘Chloranthus’
Lathyrus chloranthus
Description
I’ve longed to grow these sweet peas for many years and have finally gotten my hands on some of this hard-to-find seed. Delicate vines are covered in the most unusual acid-green miniature-flowered sweet peas that look like tiny alien faces. As blooms age, the backs of the petals show copper-orange veining. While the flowers don’t have any fragrance, they are worth growing for their unusual coloring and ability to double as a foliage. This variety has a thicker-than-average seed coating and will take longer to germinate than other varieties.
Please note: Unlike garden peas, sweet pea seeds are poisonous if ingested. Use caution around children and pets.

Seed Sowing & Growing Notes
In mild areas, seed can be sown in pots in the fall, overwintered in a sheltered spot, and planted out in spring. Everywhere else, sow seed 10 to 12 weeks before last frost and transplant out right around last frost. Provide a strong trellis or support for vines to climb.
Harvesting/Vase Life
While flowers are beautiful, their stems are so short that they are not typically grown as a cut flower. Instead of harvesting individual blooms, harvest entire vining stems. Expect a vase life of 7 to 10 days.
