Neutral | On Oct 6, 2016, ozwoz from Auckland, I have had some of these seeds planted now for a while ( about 6 months) , and various things have come up in the potting mix, but none of them I think is tropaeolum azureum. Can anyone tell me if the leaves are smooth or rough and if anyone has a close-up of a seedling and can post it that would be great! |
