I had some in a container one year and didn't bother to clear the container at season's end. I was happy to find next spring that they'd reseeded themselves and eventually flowered their heads off.

Mine were a similar colour to this.

That's good news. I would lke to grow other colours from seed next year so will save any seed pods I find.

I love 'em, but although I've had fab displays in previous years, I wasn't successful this year ... something to do with wet stuff falling from the sky perhaps!!      It won't deter me from growing them again next year, because we surely can't have another summer like this (can we??!!)

Fingers crossed that you dont. Especially as portulacas prefer dry soils.

... and dry flowers too - all those in the pic have gone like crumpled tissue paper.

When you say window trough, will a garden trough work just as well? I realise they're quite similar but I didn't know if where you put it would make a difference (the garden troughs are quite large, a couple of them I got from Garden Larch. As for the salt winds, I don't believe it has much of an effect!

I think any container in full sun and dry conditions would be fine.

Exactly. Any container will work provided there's good drainage at the bottom.
