3 Best Plants for Outside Wall Planters

Outside wall planters turn blank facades into living tapestries, adding color, texture, and movement where you least expect it. Whether you have a sunny brick patio or a shaded entryway, a well-chosen plant can thrive vertically and transform your exterior into a welcoming, personal gallery.

In this guide—curated from insights in the referenced video—we’ll spotlight three reliable stars that perform beautifully on walls: Boston ferns, geraniums, and English ivy.

You’ll find quick setup notes, care keys, and styling inspiration to spark your own design—without diving into a step-by-step technical manual. Think of this as a practical, inspiring roadmap to get you from blank wall to lush, living feature with confidence.

Before we dive in, remember that wall gardening favors plants with strong root systems, predictable growth habits, and the ability to handle the microclimates walls create—radiant heat, wind tunnels, and rain shadows. We’ll also reference ideas that pair well with long-term maintenance: irrigation lines tucked behind frames, breathable containers, and lightweight potting mixes. As you plan, consider the look you want to achieve, from a soft ferny cascade to vivid geranium bursts or the evergreen tapestry of ivy.

Why Outside Wall Planters Work

Walls modulate temperature and airflow, letting you stage plants where ground beds aren’t possible. A vertical surface also brings color up to eye level, which is ideal for entryways and patios.

Combined with hanging wall planters, framed grids, or a planter box wall, you can layer textures and bloom times to keep the display engaging throughout the season. Just ensure containers have proper drainage, anchor hardware is rust-resistant, and irrigation is easy to reach so weekly care is efficient.

3 Best Plants for Outside Wall Planters

These three picks bring distinct strengths to your wall garden: airy movement (Boston ferns), bold color (geraniums), and year-round structure (English ivy). Each includes a concise “how to set it up” so you can adapt the idea to your climate and wall conditions.

1) Boston Ferns (Nephrolepis exaltata)

Why they shine on walls: Boston ferns offer lush, arching fronds that soften hard surfaces, especially in dappled shade or bright indirect light. Their texture reads beautifully at eye level, and the gentle sway adds life to still walls. They’re perfect under eaves, on shaded porches, or along north-facing facades where heat is less intense.

Quick setup: Choose a mid-size basket or fern-friendly container with wide drainage slots. Use a peat-free, moisture-retentive mix boosted with composted bark for aeration.

Mount the basket on a sturdy bracket or into a framed wall cradle; ferns are light when dry but heavy when watered, so use anchors rated for at least 15–20 kg. Add a discreet drip emitter to keep hydration consistent.

Care keys: Keep evenly moist but never waterlogged. Mist during hot, dry spells to maintain frond turgor, and trim brown tips regularly. Fertilize lightly during the growing season. Avoid direct midday sun, which can scorch fronds on reflective walls.

2) Geraniums (Pelargonium spp.)

Why they shine on walls: Few plants deliver the punch of geraniums. Their bright clusters draw the eye from a distance and stay tidy in compact wall containers. They love sun, making them excellent for south- or west-facing walls that soak up afternoon light.

Quick setup: Use a lightweight plastic or fiberglass box with ample drainage—ideal for a narrow planter box wall or modular frame. Mix in perlite for airflow and add slow-release fertilizer. Space plants 20–25 cm apart so blooms don’t crowd, and mount boxes slightly below eye level for easy deadheading.

Care keys: Let the top few centimeters of soil dry between waterings to prevent root issues. Deadhead regularly for continual bloom. If your wall radiates heat, water in the morning so foliage can dry before nightfall. Pinch stems to keep a compact, flower-heavy habit.

3) English Ivy (Hedera helix)

Why it shines on walls: English ivy provides dense, evergreen coverage that reads like a living wallpaper. In framed planters, it delivers instant polish; in trellised pockets, it can fill gaps quickly. Ivy also tolerates partial shade and varying humidity, making it versatile for mixed exposures.

Quick setup: Use a deep wall pocket or a modular panel with root space to encourage trailing and layering. Add a slim trellis within the frame to guide growth, keeping vines off mortar or painted surfaces if you wish to avoid clinging. A drip line on a low-flow emitter maintains consistent moisture without over-wetting leaves.

Care keys: Trim quarterly to keep growth in bounds and encourage branching. Provide bright indirect light to maintain leaf variegation. Avoid overwatering in cool months and watch airflow behind dense mats; small spacer blocks between the panel and wall help prevent trapped moisture.

Design & Placement Tips

Balance structure and softness. Pair the fine texture of ferns with the bold, graphic blooms of geraniums, then use ivy as the unifying backdrop. Repeat colors in odd numbers (3, 5, 7) for rhythm, and echo leaf shapes in different sizes to avoid visual clutter.

Think maintenance first. Group plants by water needs and sun exposure so you aren’t micromanaging. Install a simple timer on your drip line; vertical containers dry faster than ground beds, especially on masonry.

Mind the microclimate. Heat-reflective walls intensify afternoon sun; choose heat-tolerant geranium varieties there, reserving shadier pockets for ferns. In windy corridors, pick deeper containers and secure brackets with masonry anchors.

Seasonal refresh. Swap in cool-season accents—like pansies or ornamental kale—around your core trio to extend interest. Keep a spare container ready to rotate in when a plant needs rehab off the wall.

Containers, Mounts & Media

For a classic look, consider powder-coated frames with coco liners; for a sleek modern vibe, try matte fiberglass modules. Stainless hardware resists rust and supports heavier, well-watered containers. A lightweight, airy medium (peat-free, bark-rich, with perlite) keeps roots happy and containers manageable on the wall.

Self-watering inserts help during heat spikes, and hidden reservoirs can be integrated behind frames. If you’re stacking modules, leave a small gap to avoid shading lower tiers, and test the wall load before full planting.

When curating a wall of mixed species, start with the backbone—ivy or other evergreen—then intersperse flowering accents like geraniums. Tuck ferns into shaded corners for contrast and movement. This layered method reads well even at a distance.

Aesthetically, repeat container shapes for cohesion. Three identical boxes in a row can feel gallery-clean, while an asymmetrical cluster adds a playful, cottage note. Either approach benefits from consistent materials and finishes.

Wall Gardening Ideas to Borrow

If you’re collecting outdoor plant wall ideas, try a grid made from repurposed balcony planters, a shadow-box frame for ferns, or a living picture crafted from ivy cuttings. Keep the color palette narrow—green and white with seasonal accents—to avoid a busy look on small patios.

For those browsing garden wall decor outdoor inspiration, mount a shallow shelf for a vintage watering can, nestle a small birdhouse between planter pockets, or thread a battery-powered fairy-light strand through the frame for evening glow. The goal is to complement, not compete with, the plants.

Prefer structure? Build a planter box wall with modular cubbies. Stagger heights so ivy can trail and ferns can drape without smothering geranium blooms. Align irrigation lines neatly along the backboard for a professional finish.

And if you’re converting a sunny fence, consider wall pots for plants outdoor made of UV-stable resin; they’re light, durable, and easy to swap as seasons change.

Before You Install: Checklist

Assess light and wind. Log sun hours on your wall for a week. Geraniums crave 6+ hours; ferns and ivy handle less. Wind exposure dictates container depth and mounting hardware.

Water plan. Drip irrigation with adjustable emitters simplifies care. For renters, quick-connect hoses and compact reservoirs keep things reversible.

Weight & safety. Wet media is heavy; confirm wall load and use prope
