Elevate Your Containers: Crafting a Lush, Layered Forest Garden Style

• Bring the depth and beauty of a forest garden to your patio or balcony.
• Think in layers: “Earth, Man, and Sky” design principles for stunning container compositions.
• Ground covers and trailing plants are the secret to a polished, cohesive look.
• Discover versatile “spillers” like Golden Creeping Jenny, Sedum ‘Angelina’, and Silver Falls Dichondra.
• Learn how using ground covers improves soil health and reduces maintenance in pots.

Step beyond the ordinary single-plant pot or the simple “thriller, filler, spiller” formula and explore the enchanting world of forest garden style containers. Imagine miniature landscapes bursting with life, where different textures and heights interplay just like the diverse layers found in a natural woodland. It’s about creating depth, visual interest, and a sense of lush abundance, even in a confined space. By focusing on the crucial element of ground cover, we can transform simple pots into captivating vignettes that evoke the richness of a forest floor spilling over the edges.

Designing with Layers: Bringing “Earth, Man, Sky” to Your Containers

Garden design principles often talk about creating layers – interest at the ground level, at eye level (or “man’s height”), and overhead (“sky”). While this is typically applied to entire garden beds or “rooms,” the same concept beautifully translates to container plantings. Every time we combine multiple plants in a single pot, we are essentially creating a micro-landscape.

Instead of just sticking one upright plant in the middle, consider how different plants occupy vertical space. This layered approach provides a richer, more dynamic composition than simply having plants that are all the same height.

Some designers use the “thriller, filler, spiller” model, which touches on layering, but it can be a bit rigid. What if your most dramatic plant also trails? What if you want a more organic, natural feel? The “earth, man, sky” concept offers a more flexible framework, encouraging you to think about plants that occupy the low space (earth), the mid-space (man), and the upper space (sky).

Over the years, I’ve found myself gravitating towards larger containers that allow for combining several plant types. This naturally leads to considering how these plants will interact and layering them effectively. And the layer that often gets overlooked, but is crucial for achieving that forest garden style containers look, is the “Earth” layer – the ground cover.

The Essential “Earth” Layer: Ground Covers and Spillers in Containers

Including a ground cover or a trailing “spiller” plant in your containers offers a wealth of benefits, far beyond just aesthetics. They are the secret ingredient that gives forest garden style containers their signature lush, finished appearance.

Why Ground Covers Belong in Pots:

• Finished Appearance: A living carpet of foliage over the soil creates a polished look, making the container feel complete and established.
• Soil Protection: Ground covers shield the potting mix from direct impact during watering or rain, preventing compaction and stopping soil from splashing onto foliage.
• Moisture Retention: By shading the soil surface, they slow down evaporation, meaning you might water less often, especially in hot weather.
• Weed Suppression: They naturally outcompete weed seeds that might land on the soil surface.
• Pest Deterrent: A dense mat can sometimes discourage squirrels from digging in your pots.
• Visual Flow: Trailing plants soften the hard edge of the container, creating a graceful transition from pot to space below.

While a layer of fine gravel or decorative stones can offer some of these benefits, a living ground cover adds dynamic color, texture, and growth that changes over time.

Using a consistent palette of favorite ground covers across multiple containers helps tie your garden together, creating a sense of unity and intentional design. It’s also budget-friendly, as many of these plants are easy to propagate by simple division.

Standout Spillers for Forest Garden Style Containers

Here are some versatile ground covers and trailing plants that are fantastic for achieving the layered look in your pots, borrowed from my own gardening adventures:

Golden Creeping Jenny

Golden Creeping Jenny is a true powerhouse for cascading beauty. Its vibrant chartreuse leaves spill generously over the sides of containers, bringing bright color and texture.

• Scientific Name: Lysimachia nummularia ‘aurea’
• Common Name: Golden Creeping Jenny
• Zone: 4-8
• Light: Full Sun to Part Shade
• Humidity: Medium to High
• Water: Medium to Wet, prefers consistently moist soil

I’ve used this prolific grower for years and rarely need to buy new plants – a small piece roots readily. It’s a hardy perennial in many areas, often taking on reddish tones in cold weather, providing year-round interest. It will happily scramble over obstacles and form a dense mat, making it perfect for filling in the “Earth” layer.

Sedum ‘Angelina’

This stonecrop cultivar is incredibly tough and beautiful, offering golden-yellow foliage that shines in sunny spots.

• Scientific Name: Sedum rupestre ‘Angelina’
• Common Name: Stone Orpine, Angelina Stonecrop
• Zone: 3-11
• Light: Full Sun
• Humidity: Low
• Water: Low, drought tolerant

Any tiny piece that breaks off can potentially root and grow into a new plant, making it easy to share and propagate. It maintains its golden color year-round and forms a lovely cascading mat. Its drought tolerance makes it a low-maintenance choice for the edge of a sunny pot.

Silver Falls Dichondra

I first fell in love with this plant seeing it spill like shimmering silver curtains from hanging baskets in a charming historic town. Its unique trailing habit and silvery-grey foliage add an unexpected touch of elegance.

• Scientific Name: Dichondra argentea ‘Silver Falls’
• Common Name: Silver Falls Dichondra, Kidney Weed
• Zone: 10-11 (Typically grown as an annual in colder zones)
• Light: Full Sun to Part Shade
• Humidity: Medium
• Water: Low to Medium, drought tolerant once established

While perennial only in warmer climates, it grows quickly from small starts, making it a wonderful annual spiller for adding cool-toned texture to your containers.

Other Great Ground Cover Options for Containers:

• Ajuga (Bugleweed): Many cultivars offer colorful foliage (bronze, purple, variegated) and short flower spikes in spring. Tolerates sun to shade depending on variety.
  • Scientific Name: Ajuga reptans (various cultivars)
  • Common Name: Bugleweed
  • Zone: 4-10
  • Light: Full Sun to Full Shade (varies)
  • Humidity: Medium
  • Water: Medium
• Leptinella: Low-growing, fern-like foliage creates a dense mat, often with interesting colors like black or silver. Great for shadier pots.
  • Scientific Name: Leptinella (various species)
  • Common Name: Brass Buttons
  • Zone: 4-10 (varies)
  • Light: Full Sun to Part Shade (prefers shade in heat)
  • Humidity: Medium
  • Water: Medium to Low
• Vinca (Periwinkle): A classic trailing evergreen with charming blue or white flowers in spring. Can be quite vigorous.
  • Scientific Name: Vinca minor
  • Common Name: Periwinkle, Dwarf Periwinkle
  • Zone: 4-9
  • Light: Full Sun to Full Shade
  • Humidity: Low to Medium
  • Water: Low to Medium

Living with Hardy Ground Covers in Pots

One important note about using these vigorous ground covers in containers is their enthusiasm! Plants like Creeping Jenny and Sedum ‘Angelina’ are incredibly hardy and will happily fill a pot entirely over time.

This means that every few years, you might need to refresh the container. You can either let the ground cover take over (which can be beautiful on its own!) or empty the pot, divide the ground cover plant, refresh the soil, and replant a smaller piece around your new feature plant. The bonus is you’ll have plenty of extra divisions to start new pots or plant elsewhere in the garden.

Using ground covers in your containers is a rewarding way to add depth, texture, and a touch of wild elegance. It’s a simple technique that elevates ordinary pots into stunning, multi-layered compositions, truly embodying the spirit of forest garden style containers.
