Winter bedding plants in shade

I made a planter for my mums decking balcony but it really doesn't get much sun, especially over the winter. Anyone got any suggestions as to what I should plant?

The compost is 5 inches deep and 6 inches wide.

I really would like to change to summer bedding next May, so, only really need a bit of colour that will survive in shade.

 

For the winter I'd put violas in that very nice long planter.
(A few cyclamen would do well in full shade)
In the summer I'd put in impatiens for a riot of colour that can handle semi shade.

 

I know it may be considered necromancy, but I would love to see how it turned out. For me, this (well-made) setup looks perfect for some kitchen herbs.

 

I'll take some pictures and get back to you maybe later today or possibly tomorrow.

 

For winter/early spring you could try the smaller bulbs, Snowdrops, Crocus and Tete A Tete Daffodils.

For summer Nemesia will cope with part shade and always put on a good display.

Looks really nice, I think, considering I thought they were all dead a few weeks ago in the hard frost.

 

Wow, this is really nice. Good job

 

Very cheery and colourful @hoofy.

 

That's brilliant @hoofy , such a simple and effective idea.

 

These winter bedding plants still look stunning, when should I be considering removing them and planting summer bedding?

 

If you are using plants in preference to growing from seed, and bearing in mind the current chilly weather, I wouldn't replace them before the end of May.

 

And does this look like a decent choice for the mostly shaded bedding trough?

 

Million bells would prefer full sun but should be okay in semi shade. The Begonias and Busy Lizzies will be fine.
