Malva
Easy-to-Grow Pollinator Flowers
Malva, commonly known as Mallow, is a versatile and charming addition to the garden.
- Charming, Cottage-Garden Appeal: Mallows have a classic, old-fashioned charm that fits perfectly in cottage gardens, informal borders, and wildflower meadows.
- Beautiful, Long-Lasting Blooms: They produce an abundance of cup-shaped flowers in shades of pink, purple, white, and sometimes even striped or veined patterns. The blooming period extends from late spring or early summer through fall, depending on the species and climate.
- Attracts Pollinators: Bees, butterflies, and other beneficial insects are drawn to Malva's nectar-rich flowers.
- Easy to Grow & Low Maintenance: Mallows are generally undemanding plants that thrive in a variety of conditions. They are often drought-tolerant once established.
- Self-Seeding (in many cases): Many Malva species readily self-seed, creating a naturalized look and providing new plants for future years. This can be a benefit or a drawback, depending on your preference.
- Edible Flowers and Leaves (some species): The flowers and young leaves of some Malva species, particularly Malva sylvestris, are edible and can be added to salads or used as a garnish. Always confirm the edibility of a specific species before consuming.
- Deer tend to leave it alone.
General Guidelines (Apply to most Malva)
- Hardiness Zones: Most Malva species are hardy in Zones 3-9, but this varies by species. Check the specific plant tag.
- Sunlight: Full sun (at least 6 hours of direct sunlight per day) is preferred for best flowering. They can tolerate partial shade, but flowering may be reduced.
- Soil: Well-drained soil is best. Mallows are adaptable to a wide range of soil types, including sandy, loamy, and clay soils, as long as drainage is adequate. They can tolerate poor soils.
- Watering: Water regularly, especially during dry periods, keeping the soil moderately moist. Established plants are quite drought-tolerant.
- Spacing: Space plants 12-24 inches apart, depending on the mature size of the variety.
Planting
- Timing: Plant Malva in spring (after the last frost) or fall.
- From Seed: Malva seeds can be sown directly outdoors in the fall or early spring. Lightly cover the seeds with soil. They often benefit from a period of cold stratification (exposure to cold temperatures) to improve germination.
- From Transplants: Plant container-grown Malva at the same depth they were growing in their pots. Handle the root ball gently.
Growing and Care
- Fertilizing: Malva generally does not require heavy fertilization. A light application of a balanced, slow-release fertilizer in early spring 1 can be beneficial, especially in poor soils.
- Deadheading: Removing spent flowers (deadheading) encourages continued blooming and prevents excessive self-seeding (if that is a concern).
- Pruning: Cut back plants by about half after the first flush of blooms to promote bushier growth and a second bloom period. In late fall or early spring, cut back any remaining dead foliage to the ground.
- Staking (for taller varieties): Taller Malva species, such as Malva sylvestris 'Zebrina' and Malva moschata, may benefit from staking, especially in windy locations.
- Mulching: Apply a layer of organic mulch to help retain moisture, suppress weeds, and moderate soil temperature.
Propagation
- Seed: The easiest and most common method. Allow some flowers to go to seed if you want self-seeding. Collect seeds from dried seed pods.
- Division: Established clumps of perennial Malva can be divided in spring or fall, although this is not always necessary.
- Cuttings: Some species can be propagated from stem cuttings taken in spring or summer.
Pests and Diseases Malva is generally trouble-free, but watch out for:
- Japanese Beetles: Can skeletonize leaves. Hand-pick or use appropriate insecticides.
- Spider Mites: Can be a problem in hot, dry conditions.
- Rust: A fungal disease that can cause orange or brown pustules on the leaves. Ensure good air circulation.
- Leaf Spot: Another fungal disease.
Popular Malva Species and Varieties
- Malva sylvestris (Common Mallow): Includes many cultivars, such as 'Zebrina' (striped flowers) and 'Brave Heart'. Often biennial or short-lived perennial, but self-seeds readily.
- Malva moschata (Musk Mallow): Pink or white flowers with a musky fragrance. Bushier habit. Perennial.
- Malva alcea (Hollyhock Mallow): Taller than M. moschata, with larger flowers. 'Fastigiata' is a popular, upright cultivar. Perennial.
- Malva neglecta (Dwarf Mallow/Common Mallow): Often considered a weed but has edible leaves and flowers. Low-growing, spreading habit. Annual or biennial.
Managing Self-Seeding Many Malva species are prolific self-seeders. This can be desirable for a naturalized look, but if you want to control their spread:
- Deadhead regularly to prevent seed formation.
- Remove unwanted seedlings as they appear.
- Mulch heavily to suppress seed germination.
Malva (mal-vuh) Mallow, High Mallow; Malvaceae Family. Hardy annuals, biennials and perennials. All have flowers in the leaf axils, pink or white and alternate leaves. Malva syvestris (sil-vess-triss); 3 foot plant with 1 inch purple rose flowers, naturalized in North America. Malva is a short-lived perennial that is often grown as a biennial. Self-seeds in optimum growing conditions.
Malva, also known as mallow, is a genus of about 30 species of herbaceous annual, biennial, and perennial plants in the family Malvaceae, native to temperate, subtropical, and tropical regions of Africa, Asia, and Europe. The genus includes the common mallow ( Malva sylvestris), the musk mallow (Malva moschata), and the tree mallow (Malva arborea). Mallow plants are known for their attractive flowers, which come in a variety of colors, including pink, purple, white, and red . They are relatively easy to grow and care for, making them a popular choice for gardeners of all skill levels . Once established, Malva requires minimal maintenance, adding to its appeal for those seeking low-effort beauty in their gardens .
Planting Malva Malva can be easily grown from seed. Sow seeds in spring or fall, about ¼ inch deep in well-drained soil. Space plants about 18 to 24 inches apart . It is worth noting that Malva can reseed itself prolifically throughout the growing season and may become invasive in some settings . To control its spread, deadhead spent blooms diligently.
Caring for Malva Water regularly, especially during dry periods , but avoid overwatering . Fertilize monthly with a balanced fertilizer . Once established, Malva plants are relatively low-maintenance . Deadheading spent blooms not only helps prevent unwanted spreading but also encourages prolonged blooming. Pruning back the plant to the main branches after the first flush of flowers can stimulate new growth and a second bloom .
Ideal Growing Conditions Malva plants prefer full sun to partial shade, ideally receiving at least 6 hours of direct sunlight daily for optimal flowering . They are adaptable to most soil conditions but thrive in well-drained soil. If your soil is heavy clay, consider amending it with some sand or compost to improve drainage . While Malva generally prefers full sun, the ideal level of sun exposure can vary depending on the specific variety and the local climate . In cooler zones, full sun to partial shade is suitable. However, in areas with hot summers, providing some afternoon shade can be beneficial . Malva tolerates strong winds but dislikes salt exposure .
Common Pests and Diseases Malva plants are generally pest and disease resistant. However, they can be susceptible to certain pests and diseases, including:
- Pests: Mallow flea beetle, capsid beetle, caterpillars, two-spotted mites, Japanese beetle, slugs, stalk borer
- Diseases: Leaf spot (Cercosporella), rust, anthracnose, crown gall, Pythium root rot
Rust can overwinter on debris left from the previous growing season, so it is essential to clean up dead leaves and plant parts in the fall .
Different Varieties of Malva There are many different varieties of Malva, each with its own unique characteristics. Some of the most popular varieties include:
- Common Mallow (Malva sylvestris): This is the most common type of Malva, featuring pink or purple flowers with dark veins.
- Musk Mallow (Malva moschata): This variety is known for its fragrant pink flowers, which have a musky scent.

- Chinese Mallow (Malva verticillata): This variety has clusters of small, white flowers and grows up to 5 feet tall.
- Tree Mallow (Malva arborea): This variety is notable for its ability to excrete excess salt through glands on its leaves, making it well-suited to coastal locations .
Uses of Malva Beyond their ornamental value, Malva plants have a history of practical uses, particularly in traditional cuisine. Young mallow leaves have a mild flavor and can be eaten raw as a substitute for lettuce in salads. Older leaves are more palatable when cooked like spinach or other leafy green vegetables. The buds and flowers can also be added to salads for a touch of color and a unique flavor. Even the small fruits that grow on the plants are edible raw . In some cultures, specific Malva species have been cultivated for culinary and medicinal purposes. For example, the Bodos of Northeast India cultivate a subspecies of Malva called lapha, which is a staple in their traditional cuisine .
Propagating Malva Malva can be propagated by seed or by cuttings .
- Propagating from Seed To propagate by seed, collect seeds from the plant after flowering. The seed pods resemble small, round balls and can be gently squeezed to release the seeds once they are dry . Sow the seeds in a well-draining seed starting mix, ideally in a seed tray or pot. Cover the seeds lightly with soil and water gently. Keep the seeds moist and in a warm, sunny location. Germination typically takes 1-2 weeks . Once seedlings have a few sets of true leaves, you can transplant them into individual pots or directly into your garden bed .
- Propagating from Cuttings To propagate by cuttings, select healthy, non-flowering stems from your Malva plant. Aim for stems that are about 4-6 inches long . Remove the lower leaves from the stem to create a bare area for root growth. Dipping the cut end in rooting hormone powder can encourage faster root development, but it is not essential . Plant the cuttings in a pot filled with a seed starting mix or a loose, well-draining potting mix. Water generously. Keep the cuttings in a bright, indirect location and maintain a moist soil condition. Roots should form in about 4-6 weeks .

Here are some characteristics of Malva:
- Herbaceous perennial:
- Malva is a flowering plant that lives for more than two years.
- Erect or decumbent branched stem: The stem of the Malva plant can grow up to 1 meter (sometimes 1.5 meters) long and can be either upright or leaning. The stems are minutely ridged and covered with fine soft hairs.
- Alternate, palmately lobed leaves: The leaves of the Malva plant are arranged alternately on the stem and have a palmately lobed shape, meaning that the lobes radiate out from a central point like the fingers on a hand. The leaves are typically rounded or kidney-shaped and have 3-7 shallow lobes.
- Flowers: Malva flowers are 0.5–5 cm in diameter and come in shades of pink, lilac, purple, or white. They have five petals and a disc-shaped center. The flowers bloom singly or in clusters of 3-5 throughout the summer.
- Fruit: The fruit of the Malva plant is a small, rounded disc-shaped structure that splits into several sections. It is said to resemble a miniature cheese wheel, which has given rise to some of the plant's common names, such as cheeseweed, cheeseplant, and common mallow.
Malva is a member of the Malvaceae family, which also includes hibiscus, cotton, and okra. The genus Malva includes about 25 species of plants, most of which are native to Europe and Asia. However, some species of Malva have been introduced to other parts of the world, including North America, where they can be found growing in waste areas, roadsides, and disturbed habitats.
Malva is a relatively low-maintenance plant that is easy to grow. It prefers full sun to partial shade and well-drained soil. Malva is also drought-tolerant once established. The flowers of Malva are attractive to bees and other pollinators. The leaves and flowers of Malva are also edible and can be used in salads or teas. However, it is important to note that Malva can cause skin irritation in some people.
There are two main ways to plant Malva: directly sowing seeds outdoors or starting them indoors (not recommended). Here is a breakdown of both methods:
Planting Malva Seeds Outdoors (Preferred):
- Timing: The ideal time for planting Malva seeds outdoors depends on your climate. In most cases, you will want to wait until after the danger of frost has passed in spring. In areas with mild winters, you can also sow seeds in the fall.
- Location: Choose a location that receives full sun to partial shade. Malva prefers well-drained soil, so avoid areas that tend to stay soggy.
- Planting: Sow the seeds directly in the garden bed where you want the Malva plants to grow. Scatter the seeds over the prepared soil surface and barely cover them with a thin layer of soil, about 1/8 inch deep.
- Spacing: Once the seedlings emerge, you will need to thin them to allow for proper growth. Aim for a spacing of 3 feet between mature Malva plants.
- Watering: Keep the soil moist until the seedlings establish themselves. After that, Malva is fairly drought-tolerant.
Starting Malva Seeds Indoors (Less Successful):
- Malva does not transplant well, so starting seeds indoors and then transplanting them outdoors is generally not recommended. However, if you are determined to try this method, you can use peat pots to minimize root disturbance during transplanting.
Here are some additional tips for planting Malva:
- You can enrich the soil with compost before planting to improve drainage and provide nutrients for the plants.
- Malva is a prolific self-seeder, so you may find volunteer seedlings popping up in your garden in unexpected places. You can either leave them be or carefully transplant them to a desired location.
- Deadheading spent flowers can encourage continued blooming throughout the season.
By following these tips, you should be successful in planting and growing Malva in your garden.
There are about 25 species of Malva plants, most of which are native to Europe and Asia. Here are some of the popular varieties:
- Common Mallow (Malva sylvestris): This is the most common type of Malva. It has pink or mauve flowers with five petals and grows up to 3 feet tall.
- Musk Mallow (Malva moschata): This variety is known for its fragrant pink flowers, which have a musky scent. It grows up to 2 feet tall and prefers full sun.
- Greater Musk Mallow (Malva alcea): This is a taller variety of Malva moschata, growing up to 6 feet tall. It has large, showy flowers in shades of pink, white, or purple.
- Dwarf Mallow (Malva neglecta): This low-growing variety is perfect for edging or borders. It has small, white flowers and grows up to 1 foot tall.
- Mauritanian Mallow (Malva sylvestris var. mauritania): This variety is prized for its unique, cup-shaped flowers in shades of pink, purple, or white. It grows up to 4 feet tall.
- Chinese Mallow (Malva verticillata): This variety has clusters of small, white flowers and grows up to 5 feet tall. It is a popular choice for cottage gardens.
These are just a few of the many varieties of Malva available. With their wide range of sizes, flower colors, and bloom times, Malva plants can be a valuable addition to any garden.
Here is how to care for your Malva once it is planted in your garden:
Sunlight and Soil:
- Malva prefers full sun to partial shade. Aim for at least 6 hours of direct sunlight daily for optimal flowering.
- They are adaptable to most soil conditions but thrive in well-drained soil. If your soil is heavy clay, consider amending it with some sand or compost to improve drainage.
Watering:
- Malva is fairly drought-tolerant once established. Water regularly during the first few weeks after planting to help the roots develop. After that, water deeply only when the soil feels dry to the touch.
- Avoid overwatering, as this can lead to root rot.
Feeding:
- Malva is not a heavy feeder and generally does not require additional fertilizer, especially if your soil is fertile. However, if your plants seem weak or show poor growth, you can give them a light feeding with a balanced fertilizer once during the growing season.
Pruning and Deadheading:
- Deadheading spent flowers throughout the blooming season will encourage continued flowering. You can simply pinch off the wilted flowers with your fingers.
- Pruning is not essential for Malva, but you can lightly prune the plants in midsummer to encourage bushier growth and more flowers.
Pests and Diseases:
- Malva is generally resistant to pests and diseases. However, they may occasionally be bothered by aphids, slugs, or powdery mildew. You can control aphids with insecticidal soap spray and remove slugs by hand. Powdery mildew can be treated with a fungicide but ensure its suitable for use on Malva.
Additional Tips:
- Malva readily self-seeds, so you may find volunteer seedlings popping up in your garden. You can either leave them be or transplant them to a desired location.
- To prevent excessive self-seeding, deadhead the flowers more frequently before they set seed.
- Malva is generally short-lived perennials, lasting 2-3 years. However, they can be easily propagated from seed to ensure a continuous display of flowers in your garden.
By following these simple care tips, you can enjoy the beauty of Malva in your garden for many years to come.
Malva definitely attracts pollinators! Here is why:
- Colorful flowers: Malva comes in a range of attractive colors for pollinators, including pink, mauve, purple, and white. These bright colors act as a beacon, inviting pollinators to visit the flowers.

- Pollen: Malva flowers also produce pollen, which is another food source for pollinators, particularly bees. While honeybees may not be particularly interested in Malva pollen, many other bee species are.
- Flower shape: The open, cup-shaped flowers of Malva are easy for pollinators of all sizes to access the nectar and pollen inside.
Overall, the combination of colorful blooms, nectar production, accessible pollen, and flower shape makes Malva a very attractive plant for a variety of pollinators. Adding Malva to your garden can not only beautify your space but also support the vital ecological role that pollinators play.
While Malva is generally a low-maintenance plant and resistant to most pests and diseases, there are a few occasional threats to watch out for:
Pests:
- Aphids: These tiny, soft-bodied insects suck the sap from Malva leaves, causing them to curl and distort.
- Slugs and Snails: These slimy creatures munch on Malva leaves, leaving ragged holes.
Diseases:
- Powdery mildew: This fungal disease appears as white powdery patches on the leaves and stems of Malva.
Let us look at how to manage these issues:
Pest Management:
- Aphids: You can control light infestations of aphids by spraying the plants with insecticidal soap spray. This is a natural and less harsh option compared to chemical pesticides.
- Slugs and Snails: Handpicking them off your plants in the early morning or evening is the most effective way to control them. You can also create a barrier around your Malva plants with crushed eggshells or diatomaceous earth, which dehydrates slugs and snails.
Disease Management:
- Powdery mildew: Good air circulation can help prevent powdery mildew. If you notice it, try spraying the affected areas with a fungicide specifically labeled for use on Malva. Opt for organic fungicides like neem oil or sulfur if possible.
Here are some additional tips to keep your Malva healthy:
- Watering: Avoid overwatering, as this can create damp conditions that favor fungal diseases like powdery mildew.
- Spacing: Ensure proper spacing between Malva plants to allow for good air circulation, which can help deter both pests and diseases.
- Removal: If a Malva plant becomes heavily infested or diseased, it is best to remove it to prevent the problem from spreading to other plants in your garden.
By following these tips and keeping an eye out for potential problems, you can help your Malva plants thrive and enjoy their beautiful flowers throughout the season.
