Description
Mixed Colours Sweet Pea Seeds 6640.
Resilient Native Climber for Vertical Colour and Erosion Control.
Mixed Colours Perennial Sweet Pea (Lathyrus latifolius) produces a vibrant array of blooms shading from deep red through rose, light pink, and pure white. Blooming from mid-June to mid-August, this rhizomatous, deep-rooted legume uses tendrils to climb 120 to 150 cm high up trellises, fences, and supports. When left unsupported, it forms a dense, sprawling ground cover 30 to 40 cm tall, making it a favourite choice for bank stabilization, erosion control, and suppressing invasive brush. Once established after its first two growing seasons, this hardy perennial requires minimal care while attracting bumblebees and butterflies to sunny garden spaces.

What you need to know to Plant & Grow
Perennial Sweet Pea seeds have very hard seed coats and benefit from soaking or cold stratification.
-
Seed Preparation: Soak seeds in water for at least 24 hours prior to sowing to break the hard outer seed coat.
-
Indoor Sowing: Start seeds indoors from March to early April in plantable peat or fibre pots using a soilless mix to protect sensitive roots during transplanting. Maintain a temperature near 15°C throughout the 15 to 25 day germination period. Grow on under lights at 15°C before hardening off and planting out after frost danger passes.
-
Outdoor Direct Sowing: Direct sow in May after soil warms, or sow in late fall. Late fall sowing naturally stratifies dormant seeds over winter for robust spring emergence.
-
Maintenance: Once established over two seasons, plants require very little intervention and thrive in full sun.
