Timing shifts with your zone — the Genie can pin down exact dates for you.
How to care for it
Scarify or soak seed overnight, then sow in early spring or fall where it is to grow — it resents transplanting. Give it lean soil; rich dirt grows leaves, not flowers.
Good companions
Wildflower meadows, poor banks, and sunny bed edges
Harvest
Let a few seed heads mature, then scatter them — lupine self-sows and spreads its fixing on its own.
