Scarify seeds by nicking the hard coat and soak in water for 24 hours before planting to improve germination. Sow seeds 1\/4 inch deep in a well-draining seed-starting mix, keeping them at 65-70°F (18-21°C). Germination can be slow and uneven, taking 14-30 days. Once seedlings have several true leaves, harden them off and transplant to the garden after the danger of frost has passed.\u003c\/p\u003e\u003cp\u003eProvide a trellis or support for the vines to climb. Water regularly during the growing season, especially during dry spells, but avoid waterlogging. Mulch around the base to conserve moisture and suppress weeds. In late winter or early spring, prune back old growth to encourage new shoots. Perennial sweet peas generally require little fertilization; a light application of compost in spring is sufficient. Monitor for pests and diseases as needed, and enjoy the return of these lovely purple blooms each year.\u003c\/p\u003e\u003ch2\u003eWhat's Included\u003c\/h2\u003e\u003cp\u003e50 Lathyrus niger perennial sweet pea seeds.\u003c\/p\u003e","brand":"Blake's Flora \u0026 Soil","offers":[{"title":"Default Title","offer_id":67776283869494,"sku":"FOLIA-519","price":27.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0994\/4884\/8694\/files\/il_fullxfull.7661703060_i16w.jpg?v=1792468629","url":"https:\/\/blakesflora.com\/products\/50-lathyrus-niger-perennial-sweet-pea-seeds-purple-climbing-vine-for-trellis","provider":"Blake's Flora \u0026 Soil","version":"1.0","type":"link"}
