Hollyhock was another option we were thinking about. I hope it gets some sort of flower on it, we have several mystery plants around here. The joys of moving into a new (old) home!
Hollyhock is a good suggestion too.
plantladylin said:From leaf photo's I've viewed it looks as if Malva has larger leaves than Alcea. For comparison, some of the images in the ATP database show fairly large leaves for Malva sylvestris:
French Hollyhock (Malva sylvestris)
French Hollyhock (Malva sylvestris 'Zebrina')
Mallow (Malva sylvestris 'Mystic Merlin')
Mallow (Malva sylvestris 'Brave Heart')
Mallow (Malva sylvestris var. mauritiana 'Bibor Felho')
Good leaf photos for Malva sylvestris also if you scorll down this page: https://en.wikipedia.org/wiki/...
Images in the ATP database also shows some Alcea with large leaves but they don't appear to be quite as large as Malva leaves:
Hollyhock (Alcea rosea)
Hollyhock (Alcea rosea 'Summer Carnival Rosy Red')
Hollyhock (Alcea rosea 'Majorette')
Hollyhock (Alcea rosea 'Scarlet O'Hara')
