Sweet Pea

Sweet Pea - Garden Basics - Flower - Annual

(Lathyrus odoratus)

The sweet-smelling flowers come in a wide range of colors and are the main feature of this climbing plant. The vine grows 6 to 9 feet tall, with dwarf types reaching 8-20 inches. Sweet peas are also suitable for baskets, tubs and spillover plantings, and make excellent cut flowers. They will do best if planted in a different place each year.

They do best in cool climates, but will grow in warmer ones. They need full sun and rich, well drained soil. Work in some compost before planting. Seeds should be sown directly where it is to grow. Soak seeds overnight then plant about an inch deep and 3-4 inches apart. Water thoroughly after planting, then restrict water until seeds germinate. Watering regularly after germination will promote good growth. Overfertilizing will cause dark green leaves and fewer flowers. The plant benefits from deadheading, but leave a few flowers at the end of the season to seed for next year.
