Incredible Proven Winners® Staircase™ Blue Lupine (Lupinus polyphyllus 'Staircase Blue') is a breathtaking perennial with tall, majestic spikes of deep blue flowers that rise above lush green leaves. This Lupine features deeply divided, palmate leaves that create a striking contrast to its vertical flower spikes.

The rich blue blossoms stand out beautifully against the foliage and can sometimes exhibit hints of violet, adding even more depth to their mesmerizing display. This hybrid Lupine is a standout in the spring and early summer garden, attracting pollinators like bees, butterflies, and hummingbirds with its nectar-rich blooms.

A compact and well-behaved variety, it reblooms with proper deadheading, providing extended color throughout the season. Growing up to 18-24 inches tall and wide, its upright form makes it ideal for adding height and structure to mixed borders. A favorite in wildflower meadows and perennial beds, it symbolizes imagination and happiness.

Care and Maintenance

Native to coastal California, it flourishes in well-drained soils with good air circulation, making it perfect for temperate gardens and areas with mild summers. As an herbaceous perennial, Staircase™ Blue Lupine dies back in winter but returns year after year with vigor. It prefers cooler conditions and well-drained soil to thrive.

• Planting Time: Spring or early fall for best establishment.
• Sun Needs: Full sun to partial shade (best flower production in full sun).
• Soil Needs: Well-drained, sandy, or loamy soils; does not tolerate heavy clay. Handles poor soil and dislikes excessive fertilization.
• Moisture Needs: Moderate water; avoid overly wet or soggy conditions.
• Mulch/Arborist Mulch: A 3-4 layer of organic, bark mulch helps retain moisture and regulate soil temperature.
• Fertilization Needs: Minimal; Lupines fix their own nitrogen, but a layer of compost in spring is beneficial.
• Pruning Info: Deadhead spent blooms to encourage reblooming; cut back in fall after dormancy begins. Not necessary, but cutting back foliage in late fall prepares the plant for winter dormancy.
• Special Needs/Perks/Growing Tips:
• Deer-resistant and relatively pest-free
• Improves soil health with nitrogen-fixing abilities
• Performs best in cool summer regions with good air circulation
