7 Light Blue Flowers to Grow In Your Garden

I’ve always thought that light blue flowers add something special to a garden that no other color can. During the daytime their rich, saturated blossoms stand out among the crowds; at dusk, when other colors recede from view, the blue ones linger longer. They make me think of English cottage gardens and pieces of pretty silk.

In addition to deep blue blossoms, I adore very pale blue flowers. Soft and delicate, they pair well with just about anything, but I particularly like them when paired with white, cream, chartreuse, light yellow, and pale pink.

Here are seven of my favorite light blue flowers:

Iris ‘Sun and Sky’

This tall bearded iris (shown above) was hybridized and registered in 1997 by Donald Spoon, so it’s a relatively new perennial in the botany world. It grows best in zones 3a to 8b and needs full sun to thrive. (For those who love to trace the heritage of hybrids, its parentage is Navajo Jewel x Clear Day.)

Amsonia hubrichtii is a herbaceous perennial. It grows well in zones 4 to 9, and only has a height of about 12 to 18 inches. It’s low maintenance and tolerates deer! It can grow in full sun to part shade. Look for the ‘Blue Ice’ variety.

Love in a Mist

Also known as Nigella damascena, this annual is in the buttercup family. It blooms in spring and early summer, and it grows from 15 to 24 inches tall. Don’t let the stunning super close-up photo here fool you: the flowers are only 1-1/2 inches across.

Forget Me Not

Called Myosotis sylvatica, the Forget Me Not is so romantic and old fashioned. It’s great for shady woodland gardens, loves mild climates, and only grows to 8 inches tall. ‘Baby Blue’ is a great hybrid from Proven Winners.

Hydrangea

Hydrangea macrophylla is a plant that I consider a core element in my garden. It blooms abundantly, and you can alter its color by adjusting acid levels in the soil (they can become pink or purple). I feel rich whenever I make large bouquets and fill my downstairs with them!

Brunnera macrophylla ‘Jack Frost’

The common name is Siberian bugloss, and it’s a herbaceous perennial that grows well in zones 3 to 8. It usually grows about 12 to 18 inches tall, and blooms in April and May. The foliage is pretty and it loves part shade. If you have rabbits, it will tolerate them.

Himalayan Blue Poppy

Meconopsis, as this is called, blooms in late spring and early summer. It, too, likes partial shade and needs rich, well drained soil to thrive, as well as regular watering. The Meconopsis ‘Lingholm’ is considered a reliable selection.


What are your favorite light blue flowers? I’d love to know.
