Hollyhocks come in a variety of types, each with its own unique characteristics and growing requirements. In this article, we will explore the different types of hollyhock plants.

Single Hollyhocks

Single hollyhocks are the most common type of hollyhock plant. They feature large, single flowers with five petals arranged around a central stamen. These flowers can grow up to four inches in diameter and come in a wide range of colors, including shades of pink, purple, white, yellow, and red. Single hollyhocks are known for their showy blooms and can reach heights of six to eight feet.

One popular variety of single hollyhock is Alcea rosea ‘Majorette Mix.’ This dwarf variety grows to a height of only two to three feet, making it suitable for smaller gardens or containers. ‘Majorette Mix’ produces an array of vibrant colored flowers and is known for its sturdy stems.

Double Hollyhocks

Double hollyhocks are characterized by their full, ruffled blooms that resemble carnations or peonies. These flowers have multiple layers of petals, giving them a lush and luxurious appearance. Double hollyhocks are available in various colors, including shades of pink, purple, white, and yellow.

One popular double hollyhock variety is Alcea rosea ‘Chater’s Double Mix.’ This mix includes a range of colors and produces large, fully double flowers that create a stunning display in the garden. ‘Chater’s Double Mix’ hollyhocks can grow up to six feet tall and are known for their strong stems and long-lasting blooms.

Miniature Hollyhocks

If you have limited space or prefer smaller plants, miniature hollyhocks might be the perfect choice for your garden. These compact hollyhocks typically grow to a height of two to three feet, making them suitable for borders, containers, or smaller gardens.

One popular variety of miniature hollyhock is Alcea rosea ‘Queeny Mix.’ This mix includes vibrant colors such as pink, purple, and white. ‘Queeny Mix’ hollyhocks have a bushy growth habit and produce an abundance of flowers that attract butterflies and bees.

Biennial Hollyhocks

Most hollyhocks are biennials, meaning they complete their life cycle in two years. In the first year, biennial hollyhocks grow foliage and establish their root systems. They do not produce flowers during this initial year. In the second year, the plants bloom and set seed before dying.

To ensure continuous flowering, it is recommended to sow biennial hollyhock seeds every year. However, some gardeners allow the plants to self-seed, resulting in new plants that will bloom in subsequent years.

Perennial Hollyhocks

In addition to biennial hollyhocks, there are also perennial varieties available. Perennial hollyhocks are long-lived plants that come back year after year without the need for replanting. These hollyhocks may not have as many color options as the biennial varieties but make up for it with their reliability.

One popular perennial hollyhock is Alcea rugosa ‘Rosa.’ This variety features beautiful pink flowers with a darker center. ‘Rosa’ hollyhocks can grow up to six feet tall and prefer full sun and well-drained soil.

Alcea ficifolia (Antwerp Hollyhock)

Alcea ficifolia, commonly known as the Antwerp hollyhock, is a unique type of hollyhock plant. Unlike other hollyhocks, it is a true perennial that can live for several years. Antwerp hollyhocks feature large, saucer-shaped flowers in shades of yellow, pink, and red.

One popular variety of Alcea ficifolia is ‘Happy Lights.’ This cultivar produces an assortment of bright and cheerful flowers and reaches a height of four to six feet. Antwerp hollyhocks are excellent for attracting bees and butterflies to your garden.

Growing Hollyhocks

Regardless of the type of hollyhock you choose, these plants generally prefer full sun and well-drained soil. They can tolerate a range of soil types but perform best in rich, fertile soil. Hollyhocks benefit from regular watering, especially during dry spells.

To grow hollyhocks from seed, sow them directly into the ground in early spring or late summer. Alternatively, you can start them indoors and transplant them outdoors once the danger of frost has passed. It is important to note that hollyhocks may not bloom until their second year, so patience is key.

In conclusion, hollyhocks are versatile and stunning plants that come in various types to suit different gardening preferences. Whether you opt for the classic single blooms, the luxurious doubles, the compact miniatures, or the reliable perennials, hollyhocks are sure to add beauty and charm to any garden.
