QUESTIONI’m sending this query on behalf of my mother: She was wondering if it is possible to keep supermarket-bought chrysanthemums growing from year to year, or do they last for one year only? ANSWERMost shop-bought chrysanthemums are grown from cuttings, with often four or five per pot. Yes, they will survive from year to year but will need to be treated as an indoor plant. They have been, most likely, grown in artificial conditions under glass, and stocked in a centrally heated supermarket under artificial lights. Leave them to flower and die back indoors and keep them inside over the winter.
