I have a beautiful very tall plant (approx 12 feet tall) in my garden but I have no idea what it is....any ideas please?
It is a Pieris. It should have beautiful young red leaves fairly soon.
Pieris, like acid soil same as Rhododendrons
Pieris 'Forest Flame'
If it seems happy then it's probably in the right place. Ideal requirements are a sheltered site in shade or part-shade in moist, peaty, acid soil.
Cut off any frost-damaged spring shoots as soon as possible. Dead-head after flowering to improve growth.
You could give it a mulch of ericaceous compost now and again in the autumn.
I agree this is Pieris sp.
However, it does not look right for Pieris Forest Flame as this usually has the red new leaves which I would expect to see.
Could it be Pieris Mountain Fire?
Pieris japonica Mountain Fire is another with red new leaves.
No sign of that in picture.
I would not like to guess which Pieris it is from one small picture.
Can you tell the difference between Pieris japonica Mountain Fire and Pieris japonica Taiwanensis from one small photo?
There are several Pieris.
Most have green leaves and pendulous small white flowers in spring.
You need an expert in Botany, with an magnifying glass, id key, and the plant infront of them to say for sure which one it is.
Which is why I say Pieris sp and am not even attempting to say which one, as it would be a complete guess.
I grow several Pieris sp and named cultivars.
But would not begin to guess which this one is.
All are beautiful!
Some are easier eg Pieris japonica Little Heath and Pieris japonica Little Heath Green ...as they are dwarf ones with tiny leaves.
Some with red flowers ... you can say that MIGHT be x or y.
But just green leaves and white flower... "No way Jose."
Have grown Forest Flame and Mountain Fire and the leaves on this look a bit darker and more leathery for either of those but they're all lovely to have no matter which variety! The new foliage is a real burst of colour in spring. Mine are just flowering now.
