Incorporating Blue and Orange Flowers into your landscape is one of my favorite ways to create instant visual drama and energy. These complementary colors sit opposite each other on the color wheel, which means they naturally intensify one another when planted together. Here is my curated collection to help you craft a breathtaking display that will transform your garden into a living work of art.
From my years of experimenting with color theory in floral design, I’ve found these stunning blooms incredibly versatile. Whether you’re planning bold, vibrant flower beds that stop traffic, or simply want to add an unexpected pop of color to your favorite vase arrangement, these selections never disappoint. Whether you’re looking to energize your garden borders or create show-stopping bouquets for your dining table, these flowers deliver spectacular results every time.
One standout that immediately comes to mind is the exotic Bird of Paradise. In my experience, its fiery orange sepals paired with iridescent blue-green foliage create an almost surreal tropical presence. Another personal favorite is the Candystripe Cosmos, which offers softer peachy-orange petals dancing around sunny yellow centers—a more subtle take on the complementary theme.
And I must mention the reliable Trailing Petunia, whose warm tangerine blooms cascade beautifully against silvery-blue foliage. Keep reading as I share my complete list with growing tips I’ve gathered from seasons of hands-on cultivation!
#1 Trailing Petunia

Commonly known as Million Bells in the horticulture world, Trailing Petunias (Calibrachoa) have earned their popularity in my container garden for good reason. I love how their profuse small trumpets in sunset oranges and corals practically glow against the cool blue-green of their foliage. From hanging baskets to window boxes, they create that coveted contrast that draws the eye immediately.
#2 Snapdragon

Snapdragons hold a special place in my spring planting routine. While they come in nearly every shade imaginable, I specifically seek out the ‘Orange Wonder’ and ‘Rocket Bronze’ varieties to pair with blue companions like delphiniums or salvias. The vertical spires create architectural interest, and that particular orange-blue pairing produces a sophisticated, almost regal atmosphere in the border that visitors always comment on.
#3 Bird of Paradise

The Bird of Paradise (Strelitzia reginae) never fails to stop me in my tracks. Native to South Africa, this tropical masterpiece produces flowers that genuinely resemble exotic birds taking flight. The brilliant orange and blue-purple “beak” emerges from a boat-shaped bract, creating one of nature’s most ingenious color combinations. In my landscaping ideas, I use it as a focal point where its structural foliage provides year-round interest even when not in bloom.
#4 Crocus

Early spring crocuses signal the end of winter dormancy, and I’ve found the variety ‘Blue Pearl’ particularly enchanting. Its soft lavender-blue petals open wide in morning light to reveal striking orange-red stigmas—the very saffron we harvest. I plant these in drifts where the low-angled spring sunlight backlights them, making that copper-orange center absolutely luminous against the cool blue petals. Morning sun followed by afternoon shade brings out their best coloration.
#5 Candystripe Cosmos

Candystripe Cosmos (Cosmos bipinnatus) earns its name from the delicate picotee edging on its petals—often in soft purple-blue shades surrounding warm peachy-orange centers. In my experience, these airy annuals are workhorses in the summer cutting garden, pumping out blooms from June until frost with minimal care. They prefer lean, well-draining soil and actually produce more flowers when not over-fertilized.
#6 Lobelia

Lobelia erinus has been my go-to edging plant for creating that coveted blue ribbon of color. The intense true-blue varieties like ‘Crystal Palace’ or ‘Cambridge Blue’ provide the perfect cool backdrop that makes neighboring orange flowers absolutely sing. I find they perform best in morning sun with afternoon shade in hotter climates, and consistent moisture keeps them flowering profusely. Their delicate appearance belies surprising toughness.
#7 Honey Bicolor Orange Flame Nemesia

Nemesia ‘Honey Bicolor Orange Flame’ has become one of my secret weapons for continuous summer color. This South African native forms neat mounds covered in small orchid-like blooms that combine warm honey-orange with cool lavender-blue in each individual flower. The fragrance is an unexpected bonus—sweet and honey-like on warm afternoons. Perfect for the front of borders or mixed containers where its compact 10-12 inch height won’t overwhelm companions.
