What’s happening to my lavender?

[Woahbodyforrrrm]

I have a beautiful lavender bush in my front garden. I cut it back a few months ago to remove all the dead wood and it has since grown exponentially. I’ve been so excited for it to flower but I’ve come to the conclusion it just isn’t going to flower properly this year. The flower heads have appeared but for some reason, only a couple of the actual flowers have emerged per head. The bees and butterflies are still loving it which makes me happy but I just don’t understand what’s happened this year. I’ve attached a photo as I may not have explained it well.

I’ve wondered whether the plant has used most of its energy growing the greenery (it’s virtually doubled in size since the start of spring) therefore just doesn’t have enough to create the flowers fully but I could well be wrong. Does anyone know what could have caused this?

I think you mean that each individual flower doesn't come in bloom simultaneously? That's normal in my garden, have attached a photo. This extends the flowering and pollen season, so definitely a good thing.

Also mine has only properly started about 2 weeks ago and I'm in the south east, if you're somewhere a bit colder/further north you'll just have to wait a bit longer.

Thanks @Agapornis I think I’m just being inpatient as they’ve been like this for about 2 weeks. I’m in Hertfordshire so south east too. I’m really pleased to hear it’s a good thing, I was beginning to worry this might be the end of my bush! Yours looks beautiful, I adore lavender!

Mine are 6-7 years old so perhaps they've both reached the end of their life! I don't mind it though, as I said it means flowers for longer, plenty of bees and low maintenance.
You could potentially plant a different variety where they do all flower simultaneously, perhaps a French one?

The flowers on French lavender don't look the same and the plants aren't as reliably hardy in the UK climate. That's why garden centres sell so many hundreds of thousands of them so cheaply every year.
