What to plant in trough?

[Gardenclems]

I’ve just emptied some pea plants out of a long trough and now it’s just sitting empty. I’m wondering what I could plant in it at this time of year. Doesn’t necessarily have to be something edible, something late flowering or that would give me a bit of colour over the autumn/winter

Pansies?

Radishes/turnips?

Red and green lettuce?

Rainbow chard, asters and cyclamen once the latter are in garden centres then some bulbs for spring,
