Blue flower I.D. please. I saw an East facing border full of this plant and would love to grow it in my garden.




Looks like a Ceratostigma plumbago Shirley.May be wrong...

Yes you are dead right, hardy plumbago. I would go for Ceratostigma griffithii which forms a sizeable shrub. Ceratostigma plumbaginoides is a herbaceous perennial who's leaves turn red or purple in autumn. But beware, it spreads underground and can be very invasive. I've just finished digging it up!

Ah,I didn't know it was a thug Jimmy. I have the one which has very light green leaves.

I have Ceratostigma griffithii which I purne lightly but the Ceratostigma plumbaginoides I have potted up and given to a couple of neighbours but with the warning.

This is a very timely question because on our last visit to a town's Park they had a number of similar flower shrubs grown as a "standard" and I was just going to post a question. Thank you.

Ceratostigma, very pretty. I've got one Siris sent me a root of a few years ago and it's coming into flower now. I keep it in a pot.

Sorry I'm late to reading these replies. All more than helpful.

We had C. wilmottianum which has an award of merit as a garden plant. Paler blue than the one shown.

That is the one we have Owl...for a few years it disappeared completely and then suddenly saw a sprig of it.Not so hardy here though.

Mine are C. willmottianum too … not only a pretty flower, but lovely autumn leaf colour as well.

We also have a pink flowered version as well.
