Mock orange looking sorry for itself :(

Planted out in late May. And leaves started to look wilted /curled in late June. They're not floppy, quite firm. No growth at all until recently and they're are a few shoots that are a couple of feet long now.

Looks nice and healthy to me🙂 There may be a little aphid damage but nothing to worry about.

Please don't think about preventative spraying because it's certainly not obvious there's a problem - just a bit of leaf curl. If you can see aphids just squish them between your fingers and consider hanging a bird feeder for blue tits nearby - they'll help to clear them.

The main thing is to keep your plant well watered and maybe give it a feed and a mulch next spring. A strong healthy plant is much more resilient to attacks from pests and disease.

There's a decent amount of growth for a plant that's only been in the ground for 10 weeks. Many shrubs follow a 3 year rule of establishment -

Year 1 'Sleep' (little top growth while they're busy establishing a root system)

Year 2 'Creep' (signs of development)

Year 3 'Leap' - and away they go!

Something very odd going on.
Two different plants maybe.
Red stem..curly leaves different from taller growing branches
Veins don't right for Philadelphus.
Curly leaf reminds be of Cornus sanguinea compressa.

Look OK to me. Older leaves do tend to curl a bit like that.  With new plants don't forget to water regularly the first year. A good soak once a week in normal weather, and more often in a heatwave.

It looks very close to the wall so may need extra care with watering.

@n.young.86 mine looks exactly the same! Did you manage to work out if anything was wrong? And has it survived?
