Hi. I grew Hibiscus acetosella from seed this spring. They are still pretty small (probably due to a combination of our lower light levels in the UK and my tardiness in potting them on) but are very attractive plants. I have a couple of questions:
1) Are they true annuals or can they be overwintered somewhere warm? (Having said that, I'm not expecting them to flower this year, given the short growing season, so I'm hoping to be able to keep a few indoors for next year.)
2) I understand the leaves are edible (pleasantly acidic, rather like sorrel - hence the "aceto" part of the name): do any of you use them in salads/cooked dishes?
Thanks a lot for your time.
