Types of Geraniums for Hanging Baskets

Types of Geraniums for Hanging Baskets

Geraniums are among the most beloved plants for gardeners due to their stunning blooms, ease of care, and versatility. While they are commonly grown in flower beds and containers, they shine particularly well in hanging baskets. With their trailing growth habits, vibrant flowers, and lush foliage, geraniums in hanging baskets add color and elegance to balconies, patios, and porches. This guide explores the different types of geraniums that are especially suited for hanging baskets, providing insights into their unique characteristics and care requirements.

1. Ivy-Leaved Geraniums (Pelargonium peltatum)

Key Characteristics:

Growth Habit: Trailing stems that can cascade up to 2-3 feet.

Flowers: Clusters of single or double blooms in shades of pink, red, white, lavender, and bicolor.

Foliage: Glossy, ivy-shaped leaves.

Ivy-leaved geraniums are the top choice for hanging baskets because of their natural trailing growth habit. They create a flowing, waterfall-like effect, making them ideal for spaces where vertical interest is desired. Their glossy leaves add a refined touch, complementing the vibrant blossoms.

Care Tips:

Sunlight: Full sun to partial shade. In hotter climates, provide some afternoon shade to prevent leaf scorch.

Watering: Keep the soil consistently moist but not waterlogged. Allow the top inch of soil to dry out between waterings.

Fertilizer: Feed with a balanced liquid fertilizer every 2-4 weeks during the growing season.

Popular Varieties:

‘Cascade White’: Features pristine white blooms.

‘Amethyst’: Known for its rich purple-pink flowers.

‘Summer Showers’: A reliable series with various vibrant colors.

2. Zonal Geraniums (Pelargonium × hortorum)

Key Characteristics:

Growth Habit: Upright but can develop a semi-trailing form when grown in hanging baskets.

Flowers: Large, rounded clusters in shades of red, orange, pink, purple, and white.

Foliage: Dark green with distinctive zones or bands on the leaves.

Zonal geraniums, while traditionally upright, are excellent for mixed hanging baskets where their bold blooms can rise above trailing plants. Their robust nature and wide color range make them a popular choice for gardeners.

Care Tips:

Sunlight: Full sun to light shade. They thrive in sunny spots with at least 6 hours of direct sunlight daily.

Watering: Water thoroughly, allowing the soil to dry slightly between waterings. Avoid overhead watering to prevent fungal issues.

Fertilizer: Use a high-phosphorus fertilizer every 2-3 weeks to promote blooming.

Popular Varieties:

‘Maverick Scarlet’: A striking red-flowered variety.

‘Rocky Mountain White’: Known for its crisp, white blooms.

‘Vancouver Centennial’: Features unique orange-red flowers with patterned foliage.

3. Scented-Leaved Geraniums (Pelargonium spp.)

Key Characteristics:

Growth Habit: Semi-trailing, depending on the variety.

Flowers: Smaller, less showy blooms in shades of pink, white, or lavender.

Foliage: Aromatic leaves with scents like lemon, rose, mint, or even chocolate.

Scented-leaved geraniums are perfect for those who value fragrance as much as visual appeal. While their flowers are modest, their scented foliage steals the show. They are ideal for hanging baskets placed near seating areas or entrances where their scent can be appreciated.

Care Tips:

Sunlight: Full sun to partial shade.

Watering: Water sparingly; these geraniums are drought-tolerant and prefer well-drained soil.

Fertilizer: A monthly dose of general-purpose fertilizer is sufficient.

Popular Varieties:

‘Lemon Fizz’: Offers a refreshing lemon scent.

‘Rose of Attar’: Features a strong rose fragrance.

‘Chocolate Mint’: A unique variety with hints of chocolate and mint.

4. Regal Geraniums (Pelargonium × domesticum)

Key Characteristics:

Growth Habit: Compact and bushy, with some varieties developing a cascading habit suitable for baskets.

Flowers: Large, velvety blooms with intricate patterns and rich colors like purple, burgundy, and white.

Foliage: Serrated leaves with a fresh green appearance.

Regal geraniums, also known as Martha Washington geraniums, are prized for their striking blooms. Although less commonly used in hanging baskets, certain varieties with semi-trailing growth can create a dramatic focal point.

Care Tips:

Sunlight: Bright, indirect sunlight or morning sun with afternoon shade.

Watering: Keep the soil evenly moist but avoid overwatering. They are sensitive to drought stress.

Fertilizer: Use a low-nitrogen fertilizer every 2 weeks to encourage flowers.

Popular Varieties:

‘Elegance Purple Majesty’: A stunning purple-flowered variety.

‘Imperial’: Features burgundy blooms with white edges.

5. Hybrid Geraniums

Key Characteristics:

Growth Habit: Varies; many hybrids are bred for hanging baskets with trailing or semi-trailing forms.

Flowers: A mix of characteristics from parent species, often larger and more vibrant.

Foliage: Can vary in texture and appearance depending on the hybrid.

Hybrid geraniums are developed to combine the best traits of different geranium types, making them versatile and highly desirable for hanging baskets. They often feature long-lasting blooms, exceptional vigor, and unique color combinations.

Care Tips:

Sunlight: Adaptable to full sun or partial shade, depending on the variety.

Watering: Moderate watering; hybrids often have improved drought resistance.

Fertilizer: Feed every 2-3 weeks with a bloom-boosting fertilizer.

Popular Varieties:

‘Calliope Dark Red’: A hybrid with intense red flowers and trailing growth.

‘Caliente Pink’: Offers vibrant pink blooms with excellent heat tolerance.

‘Cascade Pink’: A trailing hybrid ideal for baskets.

Designing Hanging Baskets with Geraniums

When creating hanging baskets with geraniums, consider mixing different types for added interest. For example, combine the cascading growth of ivy-leaved geraniums with the bold blooms of zonal geraniums. Add scented-leaved geraniums for fragrance or regal geraniums for an extra touch of elegance.

To create a balanced basket:

Choose a Centerpiece: Use upright varieties like zonal or regal geraniums.

Add Trailers: Include ivy-leaved or hybrid geraniums with trailing habits.

Incorporate Complementary Plants: Mix in trailing plants like lobelia, bacopa, or sweet potato vine for contrast.

Care Tips for Geranium Hanging Baskets

Pruning: Regularly remove spent blooms and yellowing leaves to encourage new growth and maintain a tidy appearance.

Watering: Hanging baskets dry out quickly. Check moisture levels daily, especially in hot weather, and water as needed.

Fertilizing: Use a water-soluble fertilizer to ensure nutrients are readily available to the plants.

Pest Control: Watch for common pests like aphids and whiteflies. Treat infestations with insecticidal soap or neem oil.

Winter Care: In colder climates, bring geranium baskets indoors or overwinter them in a cool, frost-free location.

Conclusion

Geraniums are a versatile and stunning choice for hanging baskets, offering endless possibilities for adding beauty and charm to any space. Whether you prefer the cascading elegance of ivy-leaved geraniums, the bold blooms of zonal varieties, or the delightful fragrances of scented-leaved types, there's a geranium for every style and setting. By understanding the unique characteristics and care needs of each type, you can create vibrant, long-lasting displays that elevate your garden or home. With proper care, geranium-filled hanging baskets can bring joy and color throughout the growing season.
