Note: The motif of non-existent plant (a new mutation?) is treated on an every-day, personal level, with no SF/F aspects. Pre-1960es editions used the period spelling "chrysanthema".

Synopsis: Enthusiastic horticulturalist recounts how he came across a unique flower from a mute village idiot and even discovered its origin, so now is "the only one in the world with a blue chrysanthemum" but can't publish it.
