Yes, I agree we need more photos :-)
This one isn't the greatest, but it gives a better impression of overall size (note the lawn grass next to it) as well as color and habit of the leaves. The photo is not of a single plant, but a cluster of self-sown plants. It was taken around 7pm, and the flowers haven't opened up yet.
I'm growing O. pallida as well this year, and its leaves are quite different in appearance. No blooms on that one, probably not before next year.
