I cant help you Im afraid owdboggy but can i ask how you managed to get yours to bulk out like that.
I have 3 diffrrent veronicastrums and they are all very sparse looking

I have always understood that variations like this may be retained through cuttings, though rarely transmitted by seed because nature always prefers to return towards the norm. Having said that, I don't know if there is any guarantee. It will be interesting to find out.

I think if you take cuttings they should retain the new habit.

If they do you may be able to name it as a new variety

You could be RICH!

:^)

I don't know about Veronicastrum, Owdboggy, but have experience with primula and fritillaria faciation. I have noticed that when these bulk up vegetatively the resultant plants/bulbs can also be faciated, but when propagated from seed the new plants grow normally. As a generalisation I would suggest that seed is probably the safer way to get new plants. Why not try both methods and see what happens. The result would be interesting and, to be quite honest, that looks to be quite a nice plant in your picture.

My Veronicastrum 'Culvers Root' also Fasciates and fascinates, too. This year it has got up really high and has several fasciated flowers on one side. Last year ,when it was dry, there were no fasciated shoots at all, and only half the height it is this year. Friends I have given rooted plants to, say their plants also have this strange habit too.

Is it a Veronicastrum? Not sure myself.
Scottish, the soil in this section of garden is extremely rich. It was the old compost heap and also the Septic tank grey water used to overflow into it until we fixed the drains properly.

Thanks Owdboggy - I do have a fairly reasonable soil - so maybe just have to wait a while :)
I thought it was veronicastrum as soon as I saw the picture Owdboggy. What makes you think different?
I have 3 different ones and the foliage looks right to me, as does the flowers.

The lack of a label on the plant!

Sorry Owdboggy....that was a stupid question now I have your answer :))

No it wasn't. I had a feeling it was a Veronica and without a label on the plant I was not sure. Nice to have it confirmed.
