Don't worry Riette, we are all new at some time to a forum! If you need any help just ask, the 'Sandbox' forum might be a good place.
Dave and his wife Trish are always willing to help, you won't find a better couple than these two! Others here will also do their best to help you find you way around so just ask.
You can edit the details to add location and date, I can't do it but each person who owns a photo can. Once a photo has been enlarged you will see links at the bottom, choose the one which says " Edit this image's caption, details, etc."
Feel free to ask for ID of any other plants you might come across.
