Sweet Pea ‘Burnished Bronze’
Lathyrus odoratus
Description
This beauty has a one-of-a-kind color but a misleading name. Flowers start out purple-maroon and shift to chocolaty-maroon as they age. Huge blooms are carried on long, strong stems.
Please note: Unlike garden peas, sweet pea seeds are poisonous if ingested. Use caution around children and pets.
Details
Height: 6 to 8 ft
Site: full sun
Days to maturity: 75 to 90 days
Plant spacing: 8 in
Pinch: when 4 to 6 in tall
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.
