Growing Foxglove in Zone 10B

Foxgloves are dramatic biennials with towering spikes of tubular flowers. Despite their beauty (and toxicity), they’re essential cottage garden plants.

Zone 10B has a very long growing season with mild winters. Many crops can be grown nearly year-round with successive plantings.

Top Growing Tips

• All parts are toxic — wear gloves and keep away from children and pets
• Biennial: sow year 1, blooms year 2, then usually dies after seeding
• Sow each year for annual flowering; they self-seed readily
• Hummingbirds and bumblebees love the tubular flowers
• Shade-tolerant; excellent for dappled light under trees

Companion Planting

Good companions: roses, ferns, hostas, astilbe

Avoid planting near: Handling without gloves — all parts toxic if ingested

Harvest Timeline

Ornamental; deadhead after peak bloom to extend flowering
