Aim to water deeply once a week, providing about 1 gallon of water per plant. In hotter weather or if you notice the soil drying out quickly, increase the frequency to every 2 to 3 days. Avoid overhead watering to minimize foliage diseases, and instead, use a soaker hose or drip irrigation to deliver water directly to the base of the plant.

  • circleLife cycle

    Lathyrus odoratus, commonly known as Sweet Pea, begins its life cycle with seed germination, typically in early spring after the last frost when the soil warms. The germinated seeds develop into seedlings with a set of true leaves, and as they mature, the plants grow rapidly, supported by a climbing habit that requires support like trellis or stakes. During the growth phase, Sweet Pea plants develop their iconic fragrant flowers, usually starting in late spring to summer, attracting pollinators and sometimes producing seeds if properly pollinated. After the flowering stage, if seeds are produced, they mature and can be collected late in the summer before the plant starts to wither. As an annual plant, the Sweet Pea then completes its life cycle by dying after seed production, with seeds overwintering to begin the next generation the following spring. The cycle of germination to seed production can vary depending on climate conditions but typically spans a single growing season.

    • Propogation time


    • Sweet pea, specifically the Lathyrus odoratus var. nanellus 'Crimson Cherub' from the Cherub Series, is most commonly propagated by seed. The best time for sowing sweet pea seeds is typically in spring, as soon as the soil can be worked, but they can also be started indoors 6 to 8 weeks before the last expected frost to get a head start. To maximize germination rates, seeds may be nicked with a file or soaked in water for 24 hours before planting. Sow the seeds about 1 inch deep and space them approximately 2 to 3 inches apart in rich, well-draining soil. Provide support for the climbing vines early on, as sweet peas will begin to vine quickly and need something to climb as they grow.
