Grow True Blue Garden Plants with Blue Flowers, Foliage, and Fruit

I’m taken with the idea of a monochromatic garden these days. Combine that with the fact that I’ve been on the hunt for true blue garden plants and I’m obsessed with blue gardens. I mean, imagine a garden that is filled with blue flowers, blue foliage, and even blue fruit. Wouldn’t that look both serene and striking all at once?


Blue flowers popping up from blue-hued foliage would take your breath away. It certainly wouldn’t be a boring garden. You can choose so many different shades of the brilliant color. The happy, bright, cornflower blue of hydrangeas (or cornflowers), the deep moody blue-black of blueberries. Purple hues. Greenish hues. And colors that have a category all to themselves: the gray/green/blue of eucalyptus.

Here is a list I put together of some of my favorite blue garden plants. I looked for unique and common blue garden plants and am so taken with what we have available to us. Thank you, Mother Nature!

    I LOVE blue in the garden! I’m currently pondering what to do with one area of my yard – have been considering making it a “Springtime” garden, but maybe I’ll make it a “Blue” garden? Will have to add that idea to the pile for consideration. Thanks for the inspiration!
