Lupine 'Russell Mix' - Classic Spires of Early Summer Color
The Lupine ‘Russell Mix’ (Lupinus polyphyllus) is celebrated for its tall, tapering spires of densely packed blooms in vivid shades of blue, pink, red, yellow, and white. This mix is known for its reliable performance and remarkable color range, offering a spectacular early-summer display that brightens any garden space. Each flower spike rises above attractive, palmate foliage, giving the plant a distinctly architectural look. As a nitrogen-fixing perennial, Lupine naturally enriches the soil, supporting sustainable gardening practices while attracting bees, butterflies, and hummingbirds in abundance.
Applications in the Garden
Perfect for cottage gardens, borders, and meadow-style plantings
Excellent companion to irises, poppies, and foxgloves for a layered early-summer display
Adds structure and height to mixed perennial beds
Useful in pollinator and wildlife gardens for its nectar-rich blooms
Suitable for naturalized or lightly managed areas with good drainage
Planting Tips - Lupine
Choose a full-sun to lightly shaded spot with well-drained, slightly acidic soil
Space plants 12–18 inches apart to allow for mature growth
Water regularly during establishment, then reduce frequency once roots develop deeply
Avoid disturbing established plants, as Lupine forms a long taproot that resents transplanting
Deadhead spent flower spikes to encourage continued blooming and prevent unwanted reseeding
Mulch lightly in winter to protect the crown, especially in colder climates
