{"product_id":"coastal-bush-lupine-lupinus-arboreus","title":"Coastal Bush Lupine | Lupinus arboreus","description":"\u003cp\u003eLupinus arboreus is a perennial shrub known by the common names Yellow Bush Lupine, Coastal Bush Lupine, and Tree Lupine. Native to coastal California and parts of western North America, it naturally grows on sandy coastal bluffs, dunes, slopes, and open scrubland. This fast-growing lupine prefers full sun, excellent drainage, and sandy or lean soil. Once established, it is drought tolerant and generally requires little to no supplemental summer irrigation.\u003cbr\u003eYellow Bush Lupine develops into a broad, rounded shrub with green to gray-green palmate leaves composed of multiple silky leaflets. In spring and early summer, the plant produces upright clusters of fragrant, pea-shaped flowers. The blossoms are usually bright yellow, although naturally occurring blue-purple forms are also found. The flowers attract native bees, butterflies, hummingbirds, and other beneficial pollinators. Like other members of the pea family, the plant can fix nitrogen and grow successfully in nutrient-poor soil.\u003cbr\u003eScarify the hard seed coat before planting by gently nicking or filing one side of each seed, or soak the seeds in warm water for 12 to 24 hours. Sow directly outdoors in fall through winter in California, or start in containers and transplant while the seedlings are still young. Avoid disturbing the developing taproot. Plant in a permanent location where the mature shrub will have sufficient room and good air circulation.\u003cbr\u003eThis species is best suited to coastal and near-coastal gardens. Plant Coastal Bush Lupine primarily within its presumed native range, from Point Reyes National Seashore south to San Luis Obispo County. Gardeners should confirm regional suitability and prevent unwanted reseeding near sensitive natural habitats.\u003c\/p\u003e\n\u003cp\u003eHeight: 4–7 feet.\u003cbr\u003eWidth: 4 feet.\u003cbr\u003eOptimum Soil Temperature for Germination: 60°F–70°F.\u003cbr\u003eBlooming Period: April–June.\u003cbr\u003eGermination: 14–30 days.\u003cbr\u003eSowing Depth: 1\/4 inch.\u003cbr\u003eLight: Full sun.\u003cbr\u003eWater Requirements: Low once established.\u003cbr\u003eSoil: Sandy, lean, and well-drained.\u003cbr\u003eLife Cycle: Short-lived perennial shrub.\u003c\/p\u003e\n\u003cp\u003ePacket contains 15 organically grown seeds, untreated, non-GMO.\u003c\/p\u003e","brand":"CaliforniaNativeSeeds.com","offers":[{"title":"Default Title","offer_id":49969339171064,"sku":null,"price":5.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0767\/8378\/0088\/files\/image_ETSY.png?v=1783916962","url":"https:\/\/californianativeseeds.com\/products\/coastal-bush-lupine-lupinus-arboreus","provider":"CaliforniaNativeSeeds.com","version":"1.0","type":"link"}
