Understanding Ice Plant Succulents: Characteristics and Benefits

Before diving into landscaping applications, it’s crucial to understand what makes ice plant succulents so special. Their defining feature is the presence of specialized cells called “bladders” or “vesicles” on their leaf surfaces. These papillae are translucent and filled with water, reflecting sunlight and creating the characteristic glistening effect. This adaptation serves multiple purposes:

Water Conservation: The bladders store water, aiding the plant’s survival in arid environments.
Sun Protection: The reflective surface helps shield the underlying plant tissue from intense solar radiation.

Temperature Regulation: The stored water can help keep the plant cooler during hot days.

Beyond their unique surface texture, ice plants offer a host of benefits for the home gardener and landscape designer:

Drought Tolerance: Their succulent nature makes them incredibly water-wise, ideal for xeriscaping and reducing water consumption.

Low Maintenance: Once established, they require minimal watering, fertilizing, or pest control.
Vibrant Blooms: Many varieties produce profuse, daisy-like flowers in a dazzling array of colors, including pink, red, orange, yellow, and white, often blooming for extended periods.
Groundcover Potential: Their spreading habit makes them excellent for suppressing weeds and preventing soil erosion.

Adaptability: They can tolerate a wide range of soil types, from sandy to clay, as long as there is good drainage.
Salt Tolerance: Some species exhibit good tolerance to saline conditions, making them suitable for coastal gardens.

Key Ice Plant Varieties for Landscaping

The term “ice plant” encompasses a broad range of genera and species within the Aizoaceae family. While many share similar characteristics, distinct varieties offer unique textures, colors, and growth habits, catering to diverse landscaping needs. Here are some of the most popular and impactful ice plant succulents for garden design:

Delosperma (Ice Plant)

This is perhaps the most well-known group, often referred to simply as “ice plant.” They are typically low-growing, mat-forming succulents with bright, prolific flowers.

Delosperma cooperi (Hardy Ice Plant): One of the most cold-hardy varieties, it produces vibrant magenta-pink flowers and spreads to form a dense carpet. It’s a fantastic choice for cooler climates.
Delosperma echinatum (Gherkin Ice Plant): Distinctive for its bumpy, finger-like leaves that resemble small pickles, it has yellow flowers and a more upright, bushy habit.

Delosperma ‘Jewel of Desert’ Series: This popular series offers a stunning range of flower colors, including vibrant reds, oranges, yellows, and purples, on compact, free-flowering plants.

Lampranthus

These are typically more upright and shrubby than Delosperma, with finer foliage and an even more spectacular floral display.

Lampranthus spectabilis: Known for its exceptionally abundant, large, daisy-like flowers that cover the entire plant, often in shades of purple, pink, or orange.

Lampranthus blandus: Features softer, more rounded leaves and produces lovely pink to lilac flowers.

Aptenia

These are vigorous, trailing ice plants often used as groundcovers or in hanging baskets.

Aptenia cordifolia (Heartleaf Ice Plant): A fast-growing, trailing succulent with heart-shaped leaves and small, bright pink flowers. It can be quite invasive in some regions, so caution is advised.

Malephora

These are more shrub-like, with fleshy, often segmented leaves.

Malephora crocea: Features bright orange-yellow flowers and slightly segmented, triangular leaves. It forms a compact, bushy mound.

Mesembryanthemum

This genus includes some well-known annual ice plants, but also perennial varieties suitable for warmer climates.

Mesembryanthemum crystallinum (Common Ice Plant): While often grown as an annual, its distinctive silvery, crystalline foliage and white to pale pink flowers make it a unique textural element.

Designing with Ice Plant Succulents: Landscape Applications

The versatility of ice plant succulents makes them suitable for a wide array of landscaping applications. Their ability to thrive in tough conditions, coupled with their stunning visual appeal, allows for creative and sustainable garden designs.

Xeriscaping and Drought-Tolerant Gardens

This is perhaps the most natural fit for ice plants. Their exceptional drought tolerance makes them ideal for creating water-wise landscapes that require minimal irrigation.

Rock Gardens: Their ability to grow in poor, well-drained soils and their compact growth habit make them perfect companions for rocks and gravel. Combine them with other drought-tolerant perennials and ornamental grasses for a naturalistic look.
Slopes and Embankments: The spreading nature of many ice plant varieties helps to stabilize soil and prevent erosion on slopes. Their low water needs mean they can thrive where other plants might struggle.

Mediterranean-Style Gardens: Their native habitat and love for sun and dry conditions align perfectly with the aesthetic of Mediterranean landscapes.

Groundcovers and Borders

Ice plants can effectively replace or supplement traditional groundcovers, offering vibrant color and suppressing weeds.

Erosion Control: Plant them on slopes or in areas prone to soil runoff.

Mass Plantings: Create carpets of vibrant color by mass planting hardy ice plants like Delosperma cooperi along pathways or in large beds.
Edging: Use more compact varieties to create colorful, low-maintenance borders along walkways, driveways, or garden beds.

Container Gardening and Hanging Baskets

Their compact growth and attractive foliage and flowers make them excellent choices for containers.

Mixed Containers: Combine ice plants with other succulents, ornamental grasses, or drought-tolerant annuals for dynamic arrangements.
Hanging Baskets: Trailing varieties like Aptenia cordifolia can cascade beautifully from hanging baskets, adding color and texture at eye level.
Terraces and Patios: Place containers filled with ice plants on patios, decks, or balconies to add pops of color and life to these outdoor living spaces.

Coastal Gardens

Some ice plant varieties exhibit good tolerance to salt spray, making them a suitable option for gardens located near the coast. Ensure good drainage, as salt buildup can be an issue in poorly draining soils.

Steps for Successful Ice Plant Landscaping

Integrating ice plant succulents into your landscape is a straightforward process, but a few key steps will ensure their health and optimal performance.

1. Site Selection and Preparation

Sunlight: Most ice plants require at least 6-8 hours of direct sunlight per day. Choose a location that receives ample sun.

Drainage: This is the single most critical factor for ice plant success. They cannot tolerate waterlogged soils. If your soil is heavy clay, amend it generously with coarse sand, gravel, or perlite to improve drainage. Raised beds are also an excellent option.
Soil Type: While they tolerate a range of soils, they prefer lean, gritty, or sandy soils. Avoid overly rich or heavily amended soils.

2. Choosing the Right Varieties

Consider your climate and the desired aesthetic. Research the cold hardiness of different species and cultivars to ensure they will survive winter in your region.

Think about the mature size and growth habit of the plant. Do you need a low-growing groundcover, a compact shrub, or a trailing accent?

3. Planting

Spacing: Space plants according to their mature size to allow for adequate growth and air circulation. Overcrowding can lead to fungal issues.
Planting Depth: Plant ice plants at the same depth they were in their nursery container. Ensure the crown of the plant is not buried.

Watering After Planting: Water thoroughly immediately after planting to help settle the soil and reduce transplant shock.

4. Watering and Fertilizing

Watering: Once established, ice plants are extremely drought-tolerant. Water deeply but infrequently, allowing the soil to dry out completely between waterings. Overwatering is the most common cause of root rot. Reduce watering significantly during winter dormancy.
Fertilizing: Ice plants generally do not require heavy fertilization. A light feeding in spring with a balanced, slow-release fertilizer formulated for succulents or cacti is usually sufficient. Avoid high-nitrogen fertilizers, which can promote weak, leggy growth.

5. Pruning and Maintenance

Deadheading: Remove spent flowers to encourage more blooms and maintain a tidy appearance.
Trimming: Trim back leggy growth or plants that are spreading too aggressively. This can be done after flowering or in spring.
Pest and Disease Control: Ice plants are generally pest and disease resistant. However, in overly wet or humid conditions, they can be susceptible to fungal diseases. Ensure good air circulation and avoid overwatering. Mealybugs or aphids can occasionally be an issue; they can usually be controlled with insecticidal soap or neem oil.
