If you’ve got a thing for blue flowers, play around with shapes, location and varieties.
_
You’ll have a permanent show of blue in all hues from spring to fall!

Even though blue isn’t a very common flower color, there are still quite a lot of plants that offer these cool-colored wonders up for us to feast our eyes!

Avoid spots with too much scorching sun.
Plant rockwall bellflower to colonize cobblestones and stone walls and let it spread a carpet of blue flowers. This perennial blooms unceasingly during the entire season.
It can cope with part shade and adapts to all types of soil. Simply remember to contain it somehow if you don’t want it to invade your entire flower bed!

For best results, select vigorous young plants that show thick, strong stems. Run the hoe often to aerate the soil and keep it cool.
Amend it with manure for maintenance every spring.
Peach-leaf bellflower sports large, upright blue flowers and revels in sun or part sun. They bloom from June to August.

Russel’s lupines add a hearty touch of indigo blue from May to July. They can deal with dry soil but don’t like chalky soil so much. Rejuvenate the clumps once every three years.
Columbine hybrids (Aquilegia), which are an intense blue, love humus-rich soil, sun and part sun. They will settle in heavy soil and possibly have a short lifespan at the start, but their self-sown offspring will cope with it increasingly better. To extend their blooming between May and July, simply retain soil coolness with a mulch made from leaves or lawn trimmings.
