Unlike annual sweet peas, this species returns year after year, producing clusters of purple, pea-like flowers that attract pollinators and add vertical interest to trellises, fences, and arbors. Its delicate foliage and twining habit make it an excellent choice for cottage gardens, meadow plantings, or naturalized areas.\u003c\/p\u003e\u003cp\u003eThis perennial sweet pea is native to the western United States and is well-suited to a range of garden settings. It thrives in full sun to partial shade and prefers well-drained soil. The vines can grow vigorously, reaching heights of 3 to 6 feet or more, and are best supported by a trellis or other structure. The purple blooms appear in late spring to summer, providing a long season of color and fragrance.\u003c\/p\u003e\u003ch2\u003ePlant Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePerennial climbing vine with purple, pea-like flowers\u003c\/li\u003e\n\u003cli\u003eAttracts pollinators such as bees and butterflies\u003c\/li\u003e\n\u003cli\u003eTwining growth habit ideal for trellises and fences\u003c\/li\u003e\n\u003cli\u003eReturns year after year in suitable climates\u003c\/li\u003e\n\u003cli\u003eNative to western North America\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eGrowing Information\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBotanical Name:\u003c\/strong\u003e Lathyrus polyphyllus\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlant Type:\u003c\/strong\u003e Perennial vine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSunlight:\u003c\/strong\u003e Full sun to partial shade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSoil:\u003c\/strong\u003e Well-drained soil\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater Requirements:\u003c\/strong\u003e Moderate; keep soil evenly moist\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrowth Habit:\u003c\/strong\u003e Climbing, twining\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUSDA Hardiness Zones:\u003c\/strong\u003e 5-9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBloom Season:\u003c\/strong\u003e Late spring to summer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMature Height:\u003c\/strong\u003e 3-6 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpacing:\u003c\/strong\u003e 6-12 inches apart\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePlanting \u0026amp; Care\u003c\/h2\u003e\u003cp\u003eSow seeds indoors 6-8 weeks before the last frost or directly outdoors in fall or early spring. Soak seeds in water for 24 hours before planting to improve germination. Plant seeds about 1\/4 inch deep in a well-draining seed-starting mix. Keep the soil consistently moist but not waterlogged. Germination can take 14-30 days at temperatures around 65-70°F (18-21°C). Once seedlings have developed 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 dry periods, and mulch to retain moisture and suppress weeds. Perennial sweet peas benefit from a layer of mulch in winter in colder zones. Prune lightly after flowering to encourage bushier growth and remove spent blooms to prolong the flowering season. Avoid over-fertilizing, as too much nitrogen can promote foliage at the expense of flowers.\u003c\/p\u003e\u003ch2\u003eWhat's Included\u003c\/h2\u003e\u003cp\u003e50 Lathyrus polyphyllus perennial sweet pea seeds.\u003c\/p\u003e","brand":"Blake's Flora \u0026 Soil","offers":[{"title":"Default Title","offer_id":67776281248054,"sku":"FOLIA-515","price":27.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0994\/4884\/8694\/files\/il_fullxfull.7712002253_rtlz.jpg?v=1792468619","url":"https:\/\/blakesflora.com\/products\/50-lathyrus-polyphyllus-perennial-sweet-pea-seeds-purple-climbing-vine-for-trellis","provider":"Blake's Flora \u0026 Soil","version":"1.0","type":"link"}
