Plant id request

[ian s]

Last year I had a lot of odd seedlings appearing in the garden where I'd spread some awful peat-free rubbish to get rid of it - most were uninteresting things but I liked the leaf shape of this one so dug it up and kept it in our unheated conservatory over winter (which might explain why it looks a bit leggy?) and a few weeks ago some flower buds appeared. One has opened, does anyone recognise what it is?
Last year - the thin green leaves in the pot are a Sprekelia





Edit - this shows the colours a bit better

Isotoma; possibly Isotoma petraea?

Thanks, it certainly does look like a pale flowered form of I. petraea. I see it's Australian so when it's planted out I'll try taking a few cuttings as winter insurance.
