The Sweet Pea Starry Night, 'Lathyrus odoratus', is an artistic blend of heirloom Old Spice sweet peas that are highly scented and heat resistant. The dark shades with cream accents evoke the look of a clear summer night. The Starry Night is a blend of violet-blue, midnight, crimson and cream-colored sweet pea 1 to 2 inch flowers. The sweet peas bloom in the spring and the duration of blooming depends on the weather. The plants stop blooming once the weather warms up. They will generally bloom 3 to 5 weeks.
A key element in successful growing of the Sweet Pea Starry Night is very early planting. The sweet pea prefers deep, rich, fertile soil. Use lots of peat or compost for early spring planting. Plant this Sweet Pea in full sun, but in a cool a spot as possible. Position them away from winds and rotate locations from year to year to prevent sweet pea pests. In cold climates plant the seed in early spring, as soon as the soil can be worked. In warm climates, plant in October through January for spring bloom. They are used for cut flowers, ground cover, fence and wall covering, and in large pots.
