I agree; blue flax is stunning, the seeds for mine sort of fell into my pocket when I was visiting a large botanical garden. It just flowers for months in poor soil and is very undemanding.
Ceratostigma wilmottianum, very blue and first choice for the hummmingbird hawkmoth when we get a summer.
Verdun, I guess I was born lucky
Nutcutlet, is this ceratostigma w. what is known as 'poor mans plumbago'? I have it in my garden, but it was given to me as a viable cutting about 10 years ago by a client as 'plumbago' but I was told by a neighbour that it was a 'fake' plumbago. Any info on that?
Might be artjak. I've heard all that genus referred to as plumbago. This one is shrubby. It sometimes dies back in a hard winter but isn't herbaceous like C. plumbaginoides. I also had C. griffithii , also shrubby but smaller, that couldn't do the winters.
Nutcutlet, I also have c. wilmotty and love it. Most years it has beautiful red autumn leaves as well as the intense blue flowers. I've always understood an alternative name for it to be hardy plumbago, artjak.
Blue flax sounds worth looking into. I hope chickens don't eat it!
FloSilverFairy, have you ever managed to propagate it? I've failed to get seed, early and late cuttings Have all died. Any suggestions?
Nutcutlet, I occasionally find self-sown seedlings and have managed to grow one on. The trouble is I'm not the most attentive of gardeners and would have more success with seedlings and maybe cuttings if I were!
Thanks Verdun, I'll give it a try. griffithii was very easy to propagate, lovely rooted cuttings by the end of summer. Dead sticks by spring.
FloSilver Fairy, maybe I leave it too late before I look for the seeds and it would be overwealmed by other stuff if it seeded ehere it is.
I love blue delphiniums, geraniums, forget me nots and my shrub ceanothus "Bleu de Versailles. I once has a beautiful blue penstemon, but I've forgotton it's name and it died in the winter.
I love penstemon and I think this is a superb collection:
Growing some of these Willow Gentian from seed at the moment, hoping to brighten up the shaded areas in my garden ........

I got a collection of penstemon from there - not flowered yet but good looking plants think blue/ purple colour.
Going to be growing blue sweet peas and cornflower and prob lots of other blue flowers I do like the colour blue
Verdun, I have read so much about what you grow in your garden which sounds wonderful and would love to see some photos. It is hard at times to visualise what someone is describing. Hope you can oblige. Look forward to seeing them.
