What are your favourite blue flowers?

[Shinyandnew1]

I love blue flowers and am trying to squeeze some more into the garden this year! I have forget me nots, borage, salvia, Felicia, brunnera, Alkanet (I know it’s a thug, but I have a little patch of it as I love the flowers!).

Can anyone recommend me some more to try to find? The more blue (not purple!), the better!

and 'Anagallis monelli'

(Sorry about multiple posts, having to look up the spelling!)

Echinops

blue spires salvia was gorgeous last year and didn't stop flowering until the first frost.

Morning glory and certain clematis. Periwinkles. Delphiniums. Bluebells.

Brachysome looks like blue fleabane, might be that.

A sea of cornflowers: bliss.

Delphiniums and bluebells.

Blue corydalis is lovely if you can get it to grow. I’m inundated with the common yellow sort, unfortunately!

Gentian.

Iris.

Forget-me-nots.

Prefer blue hydrangea to ceoanthus. I'd add some white ones as well to highlight the blue.

Perennial Flax. Like blue pennies swaying in the breeze above delicate foliage.

Blue bells are just gorgeous, and the promise of summer to come.

Catnip. The bees will thank you

Lobelia.

At this time of year, Aubretia tumbling down over a stone wall is just beautiful.

Anagalis and Anchusa. Plus blue salvias.

And don't forget pale sky blue wisteria clinging to houe walks. It's almost fully out here (Cambridge) and is lovely..
But for me the best blue flowers I've ever seen are jacaranda trees in blossom in Pretoria in spring (September). They are deep blue and so abundant Pretoria was (is?) known as Jacaranda City.

...or even house walls...

There are some lovely blue clematis if you have a wall

ceonothus.

Forget me nots (the bigger flowers jot the tiny dotty ones)

Pansies

I love my Sollya (bluebell creeper). Lovely blue flowers over a fairly long flowering period.

Anchusa azurea. Same family as forget-me-not, borage, Brunnera and alkanet, an even deeper blue than alkanet, 1-2m tall and flowers all summer. An outstandingly good plant, should be better known.

Mountain cornflower and nigella.
