About Lupine
Lupines add tall flower spires and a classic cottage-garden silhouette to mixed borders. Choose a well-drained site and follow the seed-preparation directions on your packet.
When to Plant Lupine Seeds
Follow the packet’s species-specific sowing season. Many lupines establish best in cool conditions; warm-climate and perennial types differ.
Where to Plant Lupine Seeds
Select a sunny to lightly shaded location with well-drained soil and enough room for the mature flower spikes. Avoid a waterlogged site.
How to Plant Lupine Seeds
Check whether the supplied Lupinus species benefits from seed scarification or soaking.
Direct sow where possible, or use deep pots to protect the developing taproot. Plant at the depth on the packet.
Keep evenly moist until seedlings establish, then thin rather than repeatedly disturbing the roots.
How to Harvest Lupine
Cut spikes when the lower flowers have opened and upper buds still show color. Leave some spikes to form pods if you wish to save seed; handle species-specific seed-saving rules on the packet.
How to Care for Lupine
Water during establishment and dry spells. Support tall spikes if exposed to wind and remove spent flowers if desired. Do not assume a perennial habit without identifying the species.
Companion Plants
Use with foxglove-style vertical forms and low-growing flowers, while keeping each plant’s moisture needs in mind.
