How To Create A Blue Flower Garden

Share |

Blue Lavender

Cool-color gardens create a restrained look with the use of different types of blues like soft lavender-blue to bright sky blue to cobalt blue. To achieve the desired look of a blue garden, you must have a good mix and balance of plant types. Use blue-flowering annuals, perennials and shrubs. Some plants even have bluish foliage. Plant the taller plants in the background and the shorter ones up front. Keep the ones that are going to need replanting each year within easy reach.

Amazing blue garden ideas



Lilac Shrub

Shrubs are the backbone of any garden. They are a long-lived addition and should be placed carefully. Plan their placement according to their mature size. They tend to be the tallest of your plants in a blue garden so they should be planted near the back of the garden. Some shrubs to consider are Caryopteris x clandonensis (bluebeard) and Vaccinium spp. (huckleberry).


Eryngium amethystinum

Bluish foliage can maintain a blue cast to your garden even when flowers are not blooming. Some plants with blue tones to their leaves are Eryngium amethystinum (amethyst sea holly), Baptisia australis (blue false indigo), Ruta graveolens (Rue) and Festuca cinerea (blue fescue).



Perennials will last for years. They are a long-term addition to the garden. These should be spread out in your garden so they can cover the areas where annuals and bulbs leave bare after they die back. Pinch off dying blossoms to encourage perennials to bloom all summer long. Some blue-blossoming perennials include delphiniums, Iris sibirica (Siberian iris), Campanula spp. (bellflowers), Scabiosa caucasica (pincushion flower), Cichorium intybus (chicory), Viola adnuca (blue violet) and Penstemon acuminatus (sanddune penstemon).


Blue Camomile

Annuals are flowers that die back each year. They should be in areas that are easy to cultivate and care for. Deadhead dying blooms on annuals to encourage the plants to produce blooms all season. Some blue-flowering annuals to try out in your blue garden are Ageratum houstonianum (ageratum), Brachycome iberidifolia (Swan River daisy), Browallia speciosa (browallia), Centaurea cyanus (cornflower), Consolida ambigua (rocket larkspur), Convolvulus tricolor (dwarf morning glory), Ipomoea tricolor (morning glory), Lobelia erinus (edging lobelia), Myosotis sylvatica (forget-me-not), Nemophila menziesii (baby-blue-eyes), Nigella damascena (love-in-a-mist) and Salvia farinacea (mealy-cup sage).


Bell Flower

Bulbs are used for spring color. They look best when planted in clumps of 1 or 2 dozen. This will help make a dramatic look. Some blue-blooming bulbs are Hyacinthoides hispanicus (Spanish bluebells), Scilla sibirica (Siberian squills) and Camassia quamash (camas).


As well as using plants with blue flowers and foliage, try to pick up the blue tones in statues, stones, paving, walls and fences. Furniture and garden accessories can also be painted various shades of blue to complement the garden. And if you’re still looking for ways to feature blue colours, mosaics are an excellent way of bringing a whole range of blue shades into the garden.

To complement your blue theme, as well as giving the garden a really cool summery feel, you could make a feature of clear blue water. You don’t need a swimming pool – a blue tiled pond or painted water bowl is sufficient.

Without making the garden too sunny and hot, try to bring at least some of the sky into view in the garden. On a bright summer day, the combination of blue sky, water, plants and garden accessories can be quite stunning.
