I tried to change the filled-in info about Geranium robertianum, it said 'perennial' but that should be 'annual/'biannual'. So when I tried to correct that and clicked on the 'other' option button, it didn't give me the option to fill in manually..but only gave me the choice of one of the two, so I chose for biannual but in fact it should be both..
Herb Robert (Geranium robertianum)

I wanted to add something, maybe the info is generalized for the genus Geranium.
I saw that for Geranium robertianum was also added that it can be propagated by taking semi-ripe cuttings, that cannot be as the plant doesn't make these. Also to cut the plant back all the way to the ground after flowering is not appropriate in this case.... It dies after flowering..

I know this plant, and you're right: The information about propagating by division and cuttings doesn't apply. I've removed that information from the entry. I see that you decided to change the life cycle to biennial. It grows as an annual here, so I think you should add a comment to say that it grows either as an annual or a biennial, and you could also add the information that it dies after flowering.

I corrected some spelling faults in my second post..
Zuzu, it also grows here as an annual but also as biannual depending in how late the seed(s) sprouted, it is very hardy in the winter.
I think quite some plants are annual to biannual so maybe that option could be added in the menu?
But yes, I will also add that info in a commentary..

I think I'll change the life cycle to annual. I'm not sure that a plant sprouting in winter and flowering the following spring can be classified as a biennial. That would still be an annual. Mine never grow vegetatively for an entire year before blooming the next year, which would meet the definition of a biennial plant.

I'm not sure about adding the option to the general database information. I think it's such a rare case that it can be covered in plant comments.

OK, I understand the point!
Thanks, zuzu!

The line between the two is pretty fuzzy, really. Quite a few plants are capable of acting like either a biennial or an annual depending on climatic conditions and other factors. Also, many plants that are commonly called biennials would be more properly described as winter annuals (they germinate in the fall and flower the following spring).

In this particular case, though, the plant germinates all year and flowers a few months later, so I don't think it falls into any other category than "annual." I know this because it's highly invasive in my garden and I have to pull hundreds out all year instead of just once or twice a year. I'm always tempted to keep a few in the locations where nothing else will grow, however, and it reseeds so profusely that I'll never be completely rid of it.

I just wanted to show that the USDA Natural Resources Conservation Service also uses annual/biannual for Geranium robertianum.....

Just add a comment with that information, Myriam, but please note that the correct spelling is biennial. "Biannual" means twice a year and "biennial" means once every two years.

Thanks zuzu for the spelling correction and the explanation!
