10 Unique Flower Garden Design Color Combinations You'll Love

2. Sunset Blaze: Orange and Blue

A photo of a garden with a sunset blaze color combination of orange and blue. There are tall blue delphiniums planted behind shorter orange marigolds. The orange marigolds are in full bloom, and their petals are bright and vibrant. The blue delphiniums are tall and have multiple flowers on each stem. The background contains other plants, including a white building and a green fence. The ground is covered with pine needles.

Let me tell you about my absolute favorite color combination in my garden – it’s like capturing a perpetual sunset! After 15 years of gardening, I’ve learned that orange and blue create this incredible visual impact that just stops people in their tracks.

The Perfect Orange-Blue Balance

I discovered this combination completely by accident when my supposedly purple delphiniums turned out to be the most gorgeous shade of blue next to my established marigold patch. Talk about a happy accident! The key is to plant your tall blue delphiniums behind the shorter orange marigolds to create depth and visual interest.

One thing I learned the hard way – you’ll want to stake those delphiniums early in the season. I once lost an entire row to a summer storm, and believe me, that’s not a mistake you want to make!

Adding Height and Movement

My garden really came alive when I added Mexican sunflowers (Tithonia) alongside blue salvia. Here’s a pro tip: plant them where they’ll catch the evening light. The way the setting sun hits those orange petals while the blue salvia sways in the breeze – pure magic!

The copper sneezeweed and blue globe thistle combination was actually inspired by a garden I visited in Portland. These plants are absolute pollinator magnets, and they bloom right when most gardens start looking tired in late summer.

Ground Level Magic

Down at ground level, I’ve created what I call my “sunset carpet” with nasturtiums and morning glories. The nasturtiums spread beautifully along the ground while the morning glories climb up whatever they can find. Just remember to give those morning glories something to climb on – learned that lesson when they decided my prized dahlias would make perfect climbing poles!

Maintenance Tips for Success

Plant blue flowers first as they’re typically less aggressive
Deadhead marigolds regularly for continuous blooms
Give morning glories proper support from the start
Water deeply but infrequently to encourage strong roots

I can’t tell you how many compliments I get on this color scheme. It’s become my signature garden style, and the best part? These plants are relatively low-maintenance once established. Just make sure you’re giving the delphiniums enough calcium – I add crushed eggshells to the soil every spring.
