Trailing flowering plants add charm, movement, and layers of vibrant color to small spaces, making them perfect for balconies, terraces, and hanging baskets. These plants not only maximize vertical space but also create the illusion of a lush, floral waterfall. Whether you’re after romantic pastels or bold, tropical tones, these 10 trailing flowering balcony plants will help you craft a breathtaking wall of color.
1. Petunia (Petunia × hybrida)
Classic beauty with continuous blooms.
Petunias are a balcony favorite for good reason. These cheerful, trumpet-shaped flowers come in nearly every color imaginable and bloom profusely from spring through fall. Trailing varieties like ‘Wave’ or ‘Surfinia’ are especially suited for balcony planters, spilling over edges in colorful waves. Easy to care for and sun-loving, petunias are low-maintenance but high-impact. Regular deadheading and occasional feeding will keep them lush and flowering non-stop, perfect for vibrant, long-lasting color.
2. Bacopa (Sutera cordata)
Tiny flowers, big impact.
Bacopa is a delicate-looking plant with small, five-petaled blooms in white, blue, or pink that form dense, trailing mats. It’s perfect for hanging baskets and balcony railings where it can drape elegantly. Though dainty, Bacopa is a resilient bloomer and thrives in partial to full sun. It requires little maintenance beyond watering and light feeding. The flowers create a soft, frothy effect, adding elegance and movement to compact spaces.
3. Trailing Geranium (Pelargonium peltatum)
European charm in every spill.
Also known as ivy-leaved geraniums, these classic balcony plants are beloved across Europe for their trailing stems and abundant clusters of vibrant blooms. Colors range from crimson to pink to soft lavender. They are drought-tolerant and love sunny, well-drained spaces, making them perfect for hot balconies. These low-care plants continue to flower throughout the season with just occasional deadheading and can even overwinter in mild climates or indoors.
4. Calibrachoa (Million Bells)
Mini petunias with maximum performance.
Calibrachoa offers a profusion of tiny bell-shaped flowers in vivid colors, including bicolored and veined varieties. Though they resemble miniature petunias, they are more heat- and rain-tolerant, making them ideal for unpredictable balcony conditions. Their naturally cascading habit and fast growth make them perfect for hanging baskets and railing boxes. With minimal maintenance and no need for deadheading, they deliver months of continuous blooms with little effort.
5. Nasturtium (Tropaeolum majus)
Edible beauty with a wild heart.
Nasturtiums are fast-growing, sun-loving plants with a bohemian feel. Their round, lily pad-like leaves and vibrant orange, red, or yellow flowers trail beautifully over balcony planters. They thrive in poor soil and require almost no fertilizing, making them ideal for low-maintenance gardening. As a bonus, both flowers and leaves are edible, adding peppery flavor and color to salads. This carefree climber brings life, color, and flavor to your outdoor space.
6. Lobelia (Lobelia erinus)
Electric blue and airy blooms.
Lobelia produces masses of delicate, fan-shaped flowers in striking shades of blue, purple, white, and pink. Trailing types such as ‘Cascade’ or ‘Regatta’ are perfect for hanging containers or balcony edges, where their airy form and vivid color soften hard lines. Lobelia thrives in cooler conditions and prefers partial sun, making it great for shaded balconies. With regular watering and occasional trimming, it will bloom from spring into fall.
7. Fuchsia (Fuchsia hybrida)
Elegant blooms with a tropical flair.
Fuchsia plants are known for their unique, drooping blossoms that resemble tiny ballerinas in shades of pink, purple, red, and white. Trailing varieties are ideal for hanging baskets and add a touch of romance and exotic beauty to shady or partially shaded balconies. Fuchsias appreciate regular moisture and benefit from a bit of feeding. Their continuous blooming habit and graceful appearance make them a showpiece in any vertical garden setup.
8. Sweet Alyssum (Lobularia maritima)
Fragrant carpets of tiny blooms.
Sweet Alyssum offers delicate clusters of small, sweet-smelling flowers that cascade beautifully over the edges of planters. Common colors include white, pink, and purple. This plant thrives in full sun but can tolerate some shade, and its spreading habit quickly fills containers or gaps in balcony arrangements. Its sweet honey scent attracts pollinators and adds sensory appeal. A light trim after blooming will encourage fresh growth and renewed flowering.
9. Verbena (Verbena hybrida)
Sun-loving clusters of color.
Verbena produces dense clusters of small flowers in vivid shades of red, purple, pink, and white. Trailing varieties are vigorous bloomers and tolerate heat and drought well, making them ideal for exposed balconies. Their cascading growth habit makes them perfect for containers and hanging baskets. With minimal care just full sun and occasional deadheading verbena will flower continuously from late spring until frost, offering a long season of cascading charm.
10. Ivy-leaved Toadflax (Cymbalaria muralis)
A whimsical and resilient wall-crawler.
This lesser-known gem features small, ivy-like leaves and charming, violet-lipped flowers that resemble mini snapdragons. Perfect for trailing over balcony railings or creeping along walls, it self-seeds easily and thrives in cracks, crevices, and containers. It’s especially well-suited to shaded or partially shaded areas. Ivy-leaved toadflax adds a cottage-garden touch to balconies and creates a natural, relaxed feel — a true hidden treasure for trailing beauty.
