It was in full bloom a few weeks ago, now all the flowers have disappeared; will they come back again this summer?
here is a picture

No, that's just what rhododendrons do. They're gorgeous when they're out but like all perennial shrubs they have a fairly short flowering period. They'll now be starting to grow new leaves. They don't have a second flush of flowers, you just have to enjoy them when they're at their best and look forward to them again next year.

Yes they have a short but glorious flowering season.

Try growing hydrangeas, they have a much longer flowering period.

Lol as beautiful as they are, they have the shortest flowering season.

My rhododendron blooms for about a week and looks glorious, then I get dead flowers all over the garden and have to wait until next year to see it again!

They are the grey squirrels of the plant world. Along with japanese knotweed. So you will understand why I don't want them in my garden.

I’ve tried to make my shrubs and trees all flower at different times of the year based on what they are. Magnolia now done, fruit tree blossom now done, Rhododendrons done, Azaleas almost done.

My Bleeding Heart is just coming out and my bright blue prickly bush (no idea what it’s called) is in full bloom. The chive patch is also full of flowers and the English Lavender is getting ready to bloom soon.

Come the Autumn there will be fruit on the trees and berries on the bushes with a few Sedum bushes at their best.

Garden looks shit in winter though.

The blue bush may be Ceanothus? I've been eyeing one up for my own garden.

It only flowers in the spring like many plants. Make sure you give it plenty of water over the summer to ensure they flower next spring. Also, it will be a lot happier in the ground than in the pot (the pot is too small for it really)

You can see the new leaves sprouting nicely from where the flowers were, as they should.

Agree with others that pot is too small for the plant now. Get a bigger one and make sure you use ericaceous compost, or plant out. It may or may not do well planted out depending on whether your soil is acidic or not. I get away with having acid loving plants such as Rhododendrons on neutral clay soil by treating with ferrous sulfate if the leaves start to look yellow.

I just Googled it, and it is that! thank you.

Its lovely, mine is like a bush but DD's is growing over her wall more like a trailer. It's a new house to her, so no idea whether it is a different strain of the plant or whether it has been trained that way.

There are definitely different types. I've been looking on Gardeners Dream and there are several on there. I'm going to go for Ceanothus "Trewithen Blue" I think, as it can apparently be trained up a wall. I have a place in mind next to our drive. These plants are real showstoppers in my opinion so I hope I manage to grow it well!
