The seeds from which these three plants germinated were in a seed packet which was labelled “French Marigolds”. All the other resultant plants were clearly French marigolds, and like most annuals, died at the first frost.
These three, perhaps because they were in a sheltered position on a window ledge, not only survived the winter, but started blooming again in March.
My question is should I allow some flowers to go to seed in autumn and sow them the following spring or should I take the chance of these remarkable plants surviving yet another winter? I´d really hate to lose them.
