Growing Thermopsis (False Lupine): Early Summer Spires

Thermopsis: Lupine-Like Blooms for Sunny Borders

Thermopsis (pronounced ther-MOP-sis) produces dense, pea-like flower spires on upright stems with distinctive three-lobed leaves. Blooming in late spring to early summer, it adds strong vertical accents to perennial borders.

Planting and Care

• Sun: Full sun.
• Soil: Average, well-drained soil.
• Fertilizer: Once in early spring with a balanced granular fertilizer (10-10-10).
• Water: Moderate; drought-tolerant once established.

Important Note

Thermopsis develops a deep taproot and resents disturbance. Choose a permanent location carefully; transplanting established plants is rarely successful.
