Thank you for your replies. These plants have flowered before, they are established plants.
I haven’t been on a forum before, I’ve been a keen gardener for many years and have only posted this because it has occurred, not because I’m unsure it has happened. Thanks again for your responses anyway.
If all three shrubs have produced B. davidii type flowers in the past, then @JennyJ ‘s suggestion that there is also a B. globosa growing out of the same rootball would seem most likely … can you trace the flowering stems right down to the base and see if there are actually two main stems?

I'm wondering why two of the three buddlieas didn't flower. That's very unusual unless the conditions were totally unsuitable for them. When you say they all flowered in the past - do you mean they were all purple davidiis? If so, it does suggest there's been a B. globosa in there among them, as said.
It's a place where beautiful isn't enough of a word....
I live in west central Scotland - not where that photo is...
The B. globosa must have been there all along, but maybe it didn't flower previously because the late winter/early spring pruning that works well for B. davidii would have taken off the branches that would have flowered in the spring. This year it must have been left (or not pruned as hard).

I'd agree with @Lyn as well. It can't possibly change to another type of buddleia, they're completely different plants. Pruning is probably the reason as they get pruned at different times. Globosas are done after flowering as they flower on old wood - ie the branches/stems produced the previous year, davidiis etc are pruned early in the year as they flower on the new wood.
I'm so pleased to read this.. my Globosas haven't flowered at all for a couple of years, I'm pruning them in Spring so new wood = no flowers! Thanks
I’m saddened to say that whilst I came on here for a bit of enlightenment, and a few helpful suggestions it appears that ‘some’ people on this forum are here just to judge and and express their views as the only views possible.
I’ve since spoken to a professional gardener and got the answer I needed.
I see some people on here have so many posts they must spend their entire days on here and don’t have time for actual gardening.
Some of us have been around quite a long time 🙄 … and, for some, age/infirmity means that while we may not be as active in the garden as once we were, we try to make use of our years of experience to help other gardeners.
Can you enlighten us as to what the professional gardener found?
It would be helpful to find out what it was that we didn’t spot …
😊

I'm puzzled by your comment @slennighan. I've read back and only seen that people have tried hard to find a solution for you.
I wonder what the professional gardener told you? That you had a very rare buddleia that could change its flowers from purple racemes to orange globes?

Have you got any photos? Orange buddleia sounds lovely!
