Ground cover geraniums, also known as Geranium maculatum, are a type of flowering plant that belongs to the Geraniaceae family. These plants are known for their ability to spread quickly and cover large areas, making them an excellent choice for ground cover in gardens and landscapes. With their attractive foliage and vibrant flowers, ground cover geraniums are a popular choice among gardeners and landscape designers.
Characteristics and Benefits
Ground cover geraniums are low-maintenance plants that are easy to care for. They have a spreading habit, with stems that can grow up to 12-18 inches long, and can spread up to 3-4 feet wide. They have attractive, lobed leaves that are typically 2-5 inches long and have a soft, velvety texture. The leaves are often a deep green color, but some varieties can have a reddish or purplish tint. In the spring and summer, ground cover geraniums produce vibrant, cup-shaped flowers in shades of pink, purple, and white.
One of the main benefits of ground cover geraniums is their ability to suppress weeds. They have a dense, mat-like growth habit that prevents weeds from growing, reducing the need for mulch and other weed control methods. They also attract pollinators, such as bees and butterflies, and provide a food source for them. Additionally, ground cover geraniums are drought-tolerant and can thrive in areas with poor soil, making them an excellent choice for areas with challenging growing conditions.
Cultivation and Care
To cultivate ground cover geraniums, choose a location with well-draining soil and full sun to partial shade. Plant them in the spring or fall, spacing them 12-18 inches apart. Water them regularly, but avoid overwatering, which can lead to root rot. Fertilize them annually with a balanced fertilizer, and prune them back in the fall to maintain their shape and promote new growth.
Some popular varieties of ground cover geraniums include 'Biokovo', 'Rozanne', and 'Gerwat'. 'Biokovo' is a compact, spreading variety with pink flowers and reddish-purple leaves. 'Rozanne' is a more upright variety with blue-purple flowers and deep green leaves. 'Gerwat' is a low-growing variety with white flowers and variegated leaves.
| Variety | Flower Color | Leaf Color | Growth Habit |
|---|---|---|---|
| 'Biokovo' | Pink | Reddish-purple | Compact, spreading |
| 'Rozanne' | Blue-purple | Deep green | Upright |
| 'Gerwat' | White | Variegated | Low-growing |
Pest and Disease Management
Ground cover geraniums are generally pest- and disease-free, but they can be susceptible to certain problems. Aphids, whiteflies, and spider mites can infest the plants, while root rot, leaf spot, and powdery mildew can occur in areas with poor air circulation or overwatering. To manage these problems, use integrated pest management techniques, such as introducing beneficial insects, practicing good sanitation, and using organic or chemical controls as needed.
Regular pruning and division can also help to prevent pest and disease problems. Prune the plants back in the fall to promote new growth and prevent the spread of disease. Divide the plants every 3-4 years to maintain their vigor and prevent them from becoming too dense.
Companion Planting
Ground cover geraniums can be used as a companion plant to other flowering plants, such as roses, lavender, and catmint. They can help to attract pollinators and create a beautiful, fragrant garden. They can also be used to fill in gaps between larger plants, creating a cohesive and attractive landscape.
Some other plants that can be used as companions to ground cover geraniums include creeping thyme, sweet woodruff, and phlox. These plants have similar growing conditions and can help to create a beautiful, fragrant garden.
