It is an old country saying that spindleweed grows best for the sorrowful. Verdant spindleweed in a household's garden has often brought neighbors offering consolation, usually without even asking what might be wrong.
This originates from the plant's use as a seasoning for dishes meant to speed the recovery of the infirm. A person who grows much of it is likely caring for the fatally ill.
