Getting Started with Hollyhocks

Here’s a short information chart about hollyhocks:

Understanding the Plant Hollyhocks (Alcea rosea) are biennials, meaning they complete their life cycle over two growing seasons. In the first year, they establish a sturdy root system and foliage, while in the second year, they produce their iconic flower spikes before setting seed and dying off. However, with proper care, hollyhocks can often self-sow, ensuring a continuous display year after year.

Choosing the Right Variety Hollyhocks come in a range of colors, including classic shades of red, pink, yellow, and white, as well as more unusual hues like purple and nearly black. Some popular varieties to consider include:

• Chater’s Double: Large, fully double blooms in a variety of colors
• Ourisienne: Single, ruffled blooms in shades of red, pink, and yellow
• Nigra: Deep maroon, nearly black blooms for a dramatic impact

Planting Hollyhocks

Site Selection

Hollyhocks thrive in full sun, requiring at least six hours of direct sunlight per day. They also prefer well-draining soil that is rich in organic matter. Avoid planting in areas with heavy, clay soils or poor drainage, as this can lead to root rot and other issues.

Soil Preparation

Before planting, amend the soil with compost or well-rotted manure to improve drainage and nutrient content. Hollyhocks appreciate a slightly alkaline soil with a pH between 6.5 and 7.5, so consider adding lime if your soil is overly acidic.

Sowing Seeds or Transplanting

Hollyhocks can be grown from seed or purchased as seedlings or young plants. If sowing seeds directly in the garden, plant them 1/4 inch deep and 12 to 18 inches apart in early spring or late fall. For transplants, space them 18 to 24 inches apart, taking care not to damage the taproot.

Caring for Hollyhocks

Watering

Hollyhocks have moderate water needs, requiring about 1 inch of water per week during the growing season. Water deeply and consistently, taking care not to overwater or allow the soil to become waterlogged, as this can lead to root rot.

Fertilizing

Apply a balanced, slow-release fertilizer in early spring and again after the first flush of blooms. Hollyhocks are heavy feeders, and proper fertilization will promote healthy growth and abundant flowering.

Staking and Support

As hollyhocks mature, their tall flower spikes can become top-heavy, making them susceptible to wind damage or breaking. To prevent this, provide support by tying the stems to sturdy stakes or installing a trellis or cage system.

Pruning and Deadheading

Regular deadheading (removing spent blooms) will encourage hollyhocks to produce more flowers throughout the season. In late fall or early spring, cut back the dead foliage to the ground to tidy up the plant and prevent disease.

Pests and Diseases

Hollyhocks are generally resilient, but they can be susceptible to issues like rust, leaf spot, and Japanese beetles. Monitor plants regularly and address any problems promptly with appropriate organic or chemical controls.

Incorporating Hollyhocks into Your Garden Design

Borders and Backgrounds

With their towering height and striking color, hollyhocks make excellent additions to borders, cottage gardens, and backgrounds. Place them toward the rear of garden beds to create a stunning vertical element.

Cut Flowers

Hollyhock blooms make beautiful and long-lasting cut flowers for indoor arrangements. Cut the stems in the morning and immediately place them in water for best vase life.

Companion Planting

Hollyhocks pair well with a variety of other cottage garden favorites, such as daylilies, foxgloves, and peonies. They also complement lower-growing plants, like lavender and catmint, creating a beautiful and harmonious display.
