Best blue flowering plant

well,I like to see a wood of bluebells,also grape Hyacintha's are lovely with the perfume,dutch iris the small ones,and of course clematis Mr young can look pretty good too!

Many perennial Salvias are an amazing blue

Lithadora Heavenly Blue is wonderful as is Grace Ward.

I like Ageratum fluffy plant looks pretty low growing, I like blue cornflower and small blue sweet peas.

Blue and yellow flowers do look nice together

Do you grow lots of blue flowers?

Currently growing these Willow Gentian from seed.  Hoping to brighten up the shaded areas of my garden.......

I love cornflowers in blue, reminds me of my Mum's garden.  Cant establish them myself use seeds, any tips out there for wild blue flowers

I have a lot of cornflowers in my front cottage garden.  I find seeds from packets do not always work that well.  A few years back I brought a couple of plants then when they died off I collected the seeds and scattered them in the garden at the same time as they would normally drop from the plant when it had died.  I now do this every year with my cornflower plants and always have a good show.

I'm for bluebells to. they are now out in the woods at the back of my house when you walk through they smell devine

Not exotic but delphiniums are great plants and there are some fantastic shades of blue out there. I also have a fair few hardy geraniums which should be flowering very soon, given a bit of sunshine, very easy plants that give a lot.

At moment I have blue delphiniums, lupins, penstemons, linum, geranium, tradescantia, lithodora, dwarf phlox, all in flower.  A couple of salvIas are soon to open their buds into blue flowers as well as agastaches not far off.

Love blue flowers and the summer will provide even more

I must admit blue is one of my favourite colours too (even my wardrobe). You're way ahead of me Verdun, only a couple of geraniums are near to flowering here. Delphiniums, lupins and pentomens must be weeks away yet. I also have a fondness for blue Clematis 

...don't have many blues, but I love that Gentian up above there... 

Aster frikartii Monch... the best one I have... makes a good splash..

I have a lovely blue in buglossoides purpurea (or something very close) out now and spreads by putting out 'feelers' which root down. 

Did you have to adjust your photo in the computer to get that blue Bagz. I can never get a really good blue in a photo.

My favourites i guess would be Aster Novi Belgii. Scilla peruviana and Camassia leichtlinii, oh not forgetting Chionodoxa forbesii (mainly because it`s so early in the season)

Chinodoxa - lovely a fore runner of spring I think and I have an amazing deep blue ceanothus - concho- up the wall at the front. Only coming to the end of its first year now.

And I also love caryopteris, but i ate summer there are usually a lot of blue flowers about. Also I have planted a screen of Russian sage (perovskia) well 2 plants close together that leave an ethereal impression in ne part of the garden.

I love all the blues - but delphiniums have to be my all time favourites

Forget me nots. Just love 'em, easy peasy self seeders, pull out the excess, then the whole plants as they go over or are shading out perennials coming into growth. 

I love delphiniums too, chicky. I love my deciduous ceanothus, Gloire de Versailles. I have ageratum, Blue mink, grown from seed, blue irises and I'm waiting for my anchusa to come out - it's in bud. I have green, and gold leaved caryopteris for later in the year. A beautiful clear blue clematis has come out, but I've forgotten what it is. My Multi-blue, which is flowering, is more purpley.
