❓ FAQ

When should I plant hollyhock seeds?

Sow outdoors about a week before your last frost, or in late summer/fall. You can also start indoors about 6–9 weeks before the last frost and move seedlings outside 2–3 weeks after it passes.

Where should I plant them?

Choose a sunny spot with moist, rich, well-draining soil. Because they grow tall, planting near a fence, wall or trellis helps protect them from strong winds. Space plants 12–18 inches apart.

How do I plant the seeds?

Hollyhock seeds need light to germinate. Press them gently onto the soil surface and barely cover them. Soaking seeds in warm water for 12 hours is optional. If starting indoors, use tall pots, as hollyhocks have long taproots.

Do hollyhocks come back every year?

Hollyhocks are biennials or short-lived perennials. They usually grow leaves the first year and bloom the second. They drop seeds easily, so new plants keep popping up and your display can last for years. Removing faded flowers can also extend the plant's life.

How do I keep them healthy?

Rust and powdery mildew love damp conditions. Plant in a sunny, airy spot, water at the base instead of the leaves, and remove affected lower leaves early.

Are hollyhocks safe for pets?

Hollyhocks are generally considered non-toxic to dogs and cats, but the hairy stems and leaves may irritate sensitive skin.

What pairs well with hollyhocks?

Roses, delphiniums, foxgloves, peonies, tall phlox and ornamental grasses all make beautiful cottage-garden companions.

Note: Each plant blooms in its own color; mixed packs create a rainbow effect when planted together. Growth and results vary with climate and care.
