    • Alcea

    Hollyhocks provide excellent architectural height in the garden and make good backdrops for lower growing perennials. Try growing them in the cottage garden style by planting them up against a wall or picket fence. Though their stalks are very strong, they may need to be staked if they are planted in a windy site.

    Hollyhocks will grow in average, medium, well-drained soils, although they prefer rich, moist, well-drained soil. Tolerant of short drought periods, but not wet soils in winter. They need full sun to really perform in the landscape.

    Did you know that Hollyhock flowers are edible? Though they don't have much flavor, they make a showy edible garnish for summer dishes.

    Alcea rosea, commonly known as hollyhock, is a classic cottage garden favorite, prized for its tall spires of showy flowers in a wide array of colors. This biennial or short-lived perennial can add a touch of old-fashioned charm to any garden. Here is what gardeners should know about growing and caring for Alcea rosea:  

    Planting Alcea Rosea

    • Sunlight and Soil Hollyhocks thrive in full sun, needing at least 6 hours of direct sunlight daily . They tolerate a wide range of soil conditions, including clay, loam, and sand, but prefer well-drained soil . They will not tolerate wet winter soils .  
    • Planting Depth Sow seeds directly outdoors about a week before the last frost, planting them just ¼ inch deep and about 2 feet apart . If starting seeds indoors, use tall, individual pots to accommodate the long taproots and transplant early to avoid damage . When planting established plants, ensure the top of the root ball is level with the soil line .  

    Caring for Alcea Rosea

    • Watering Hollyhock seedlings prefer damp conditions . Water new plants when the top inch of soil starts to dry out . Established plants require more consistent watering, especially during hot, dry periods . Water thoroughly and allow the soil to dry slightly between waterings .  
    • Fertilizing In fertile soils, fertilizing may not be necessary . However, in poor soils, feeding every two to four weeks during the bloom period can be beneficial . Use an organic flower fertilizer or a fish emulsion that is high in nitrogen . You can also use a fertilizer with higher levels of phosphorus to support blooming .  
    • Pruning Prune hollyhocks during the spring and summer when they are blooming . Pinch back flowers when they start to die . In early September, cut them down to keep their seeds from spreading . You can also cut back the entire stalk to the base after flowering to prevent seed heads from forming . To prevent rust disease from overwintering, cut back all stems and leaves to the ground in winter .  

    Pests and Diseases Hollyhocks are susceptible to several pests and diseases, including:

    • Hollyhock rust: This fungal disease is the most common problem for hollyhocks, causing yellow or orange spots on the leaves, stunting, and premature leaf drop .  
    • Leaf spots: Caused by various fungi, leaf spots can appear as circular or angular spots on the leaves .  
    • Pests: Hollyhocks can be affected by pests such as slugs, snails, Japanese beetles, spider mites, and fourlined plant bugs .  

    To prevent these problems, ensure proper air circulation, avoid overhead watering, and remove infected plant parts. You can also use fungicides or insecticides if necessary.

    Varieties of Alcea Rosea Alcea rosea comes in a wide variety of colors and forms. Some popular varieties include:  

    • 'Spotlight Series': This series offers single-flowered varieties in a range of colors, including deep black-purple, red, pink, yellow, and white .

    Alcea rosea is a beautiful and relatively easy-to-grow plant that can add height and color to any garden. By understanding its basic needs and providing proper care, gardeners can enjoy these stunning blooms for years to come.

    Hollyhocks (Alcea rosea) are charming flowering plants, often found gracing gardens with their colorful presence. While they readily reseed and form colonies, they are rarely found in the wild. Originating perhaps in Turkey, they are likely a cultivated variety, sometimes listed under the name Althaea in plant catalogs.

    These beauties thrive in sunny spots with rich soil, and reward gardeners with towering spikes of blooms in a rainbow of hues, from soft lavenders to vibrant reds and yellows. Their flowers, reminiscent of poppies, adorn the garden from June to August. Although they prefer full sun and fertile conditions, hollyhocks are adaptable and can tolerate some shade and a variety of soils. However, good drainage is essential, especially during winter months.

    While typically reaching heights of 5 to 8 feet, their sturdy stalks usually require no support. Considered biennials or short-lived perennials, they readily self-sow, ensuring a delightful display year after year.

    Hollyhocks are a joy to grow, adding vertical interest and old-fashioned charm to gardens. Here is a guide to successful cultivation:

    1. Planting

    • Timing: Sow seeds outdoors in late spring or early summer or start indoors 6-8 weeks before the last frost. For fall planting, sow seeds in late summer or early fall.
    • Location: Choose a sunny spot that receives at least 6 hours of direct sunlight per day.
    • Soil: Hollyhocks prefer well-drained soil that is rich in organic matter. Amend heavy clay soil with compost to improve drainage.
    • Spacing: Space plants 18-24 inches apart, as they can grow quite tall and wide.

    2. Soil Preparation:

    • Before planting, amend the soil with compost or well-rotted manure to improve drainage and fertility.
    • If your soil is heavy clay, consider adding sand or grit to improve drainage.

    3. Watering:

    • Water regularly, especially during dry spells, to keep the soil consistently moist but not waterlogged.
    • Deep watering encourages deep root growth, which helps the plants withstand drought and strong winds.

    4. Fertilizing:

    • Hollyhocks are not heavy feeders, but they benefit from a light application of balanced fertilizer in spring.
    • Avoid over-fertilization, as this can lead to excessive foliage growth and fewer flowers.

    5. Staking:

    • Taller varieties may require staking to prevent them from flopping over, especially in windy conditions.
    • Use sturdy stakes and tie the stems loosely to allow for some movement.

    6. Deadheading:

    • Remove spent flower spikes to encourage repeat blooming and prevent self-seeding, if desired.
    • If you want the plants to self-sow, leave some of the flower spikes to mature and release their seeds.

    7. Pest and Disease Control:

    • Rust: Hollyhocks are susceptible to rust, a fungal disease that causes orange spots on the leaves. To prevent rust, ensure good air circulation, avoid overhead watering, and remove infected leaves promptly.
    • Other pests: Watch for Japanese beetles, spider mites, and leaf miners. Treat infestations with appropriate organic or chemical controls.

    8. Winter Care:

    • In colder climates, mulch around the base of the plants in late fall to protect the roots from freezing temperatures.
    • Cut back the stalks to ground level after they die back in fall or winter.

    9. Propagation:

    • Hollyhocks can be grown from seed. Collect seeds from mature plants and sow them directly outdoors or start them indoors.
    • Some varieties can also be propagated by root cuttings.

    Additional Tips:

    • To prevent rust, choose rust-resistant varieties and avoid overcrowding plants.
    • Hollyhocks are biennials, meaning they typically bloom in their second year and then die. However, they often self-sow, creating new plants for the following year.
    • Consider planting hollyhocks along fences or walls to provide support and create a dramatic backdrop.

    By following these guidelines, you can cultivate healthy and beautiful hollyhocks that will add a touch of cottage garden charm to your landscape.

    Spring

    • Planting: Sow seeds outdoors or transplant seedlings after the last frost.
    • Fertilizing: Apply a balanced, slow-release fertilizer.
    • Staking: Begin staking taller varieties as they grow.
    • Pest and Disease Monitoring: Watch for early signs of rust or other pests.

    Summer

    • Watering: Water regularly, especially during dry periods, ensuring deep watering.
    • Deadheading: Remove spent flower spikes to encourage repeat blooming or leave some for self-seeding.
    • Pest and Disease Control: Continue monitoring and address any issues promptly.
    • Support: Adjust stakes as needed to accommodate growth.

    Fall

    • Mulching: Apply a layer of mulch around the base of the plants for winter protection.
    • Cleanup: After the first frost, cut back dead stalks to ground level. (Some gardeners prefer to leave stalks for winter interest.)
    • Seed Collection: If desired, collect seeds from mature flower spikes for future planting.

    Winter

    • Minimal Care: Hollyhocks are generally dormant in winter.
    • Protection: In colder regions, provide extra winter protection with evergreen boughs or a frost blanket, if desired.

    Additional Notes:

    • Hollyhocks are biennials, meaning they typically flower in their second year.
    • To encourage self-seeding, allow some flower spikes to mature and release seeds.
    • Good air circulation is crucial to prevent rust.
    • If rust appears, remove and destroy affected leaves.
    • Consider replacing hollyhocks every 2-3 years to maintain vigor and prevent disease buildup.

    This calendar provides a general framework for Alcea rosea care. You may need to adapt the timing and intensity of tasks based on your specific climate, growing conditions, and hollyhock variety.
