Adding Colour to Garden Borders

[CuriousPebble]

I have a back border and side borders in my garden that are too green. I'd like to add some colour, but not with annuals. I'm considering climbing roses, but the rear border gets little sun due to a fence, even though the garden is south-facing. Any suggestions?

I've just added a couple of hydrangeas. They don't mind light shade and are colourful for a long time.

you could have roses, it’s a lovely fence for something climbing. A repeat flowered would be better. Them I’d pop yo garden centre each month for when the rose isn’t flowering and add something that catches your eye. Some more height might be good, a standard tree perhaps?

For the beds, I would thin out what you have and add some perennials like Geum, Phlox, Lupins, Asters, Hardy Geranium (the purple ones are lovely)
Plant some bulbs for later on, daffs, tulips, etc. and maybe some primroses.
For the fence, maybe honeysuckle, clematis, or a rose (not all need lots of sun)

Ooh a standard tree is a good idea. I have one of these in a huge pot. Loads of seasonal interest. I love it. Bright pink and white leaves in spring and summer; Salix Integra (flamingo willow)

What's the soil like? I've got a shady damp back border that has various including hydrangeas, purple loosestrife, astilbes, anemones. Rhododendrons and azaleas are bit earlier on, and I've recently added a pieris 'forest flame' which should have lovely red foliage and white flowers in spring (I've got one in a pot elsewhere)

Clematis?
