Bold, Spiky Blooms of Brilliant Golden Yellow to Brighten Summer Borders and Wildflower Beds.
Golden Yellow Lupine (Lupinus luteus) is a striking open-pollinated annual featuring tall, sunny columns of brilliant golden-yellow flowers that bloom from late spring into early summer. Reaching a mature height of 60 cm, these bold, spiky blossoms rise above attractive palmate foliage, creating a dramatic focal point in annual beds, cottage gardens, and wildflower plantings.

What you need to know to Plant & Grow
Lupines feature hard seed coats and taproots that dislike disturbance; scarification or soaking prior to sowing ensures optimal germination performance.
-
Seed Preparation: To break seed dormancy, nick or scarify the hard outer coating gently with a file or sandpaper, or soak seeds in warm water for a few hours prior to planting to allow moisture penetration.
-
Direct Sowing (Recommended): Direct sow pre-treated seeds outdoors in mid to late May once soil has warmed. Sow seeds 6 mm deep in a sunny to partially shaded location.
-
Indoor Starting: Start indoors 4 to 6 weeks before your last expected spring frost date using peat pots or soil-less cell packs to minimize root disturbance during transplanting.
-
Germination & Spacing: Seeds germinate within 15 to 25 days. Thin or space young plants to 30 cm apart.
-
Soil & Self-Seeding Care: Thrives in poor, sandy, well-drained soils where other plants struggle. Plants have a strong natural tendency to self-seed, providing naturalized blooms year after year.
