Birth flower

Lily of the valley

Convallaria majalis. In the language of flowers, as lists print it today, it stands for returning happiness, the reading Kate Greenaway printed for it in 1884. It is a custom of sentiment, not a scientific or official designation.

Where the names come from

The name translates the Latin lilium convallium of the Vulgate Bible, itself a literal rendering of a Hebrew phrase in the Song of Solomon, chapter 2, verse 1. German herbal writers of the 1500s seem to have been the first to attach it to this plant. The genus name, Convallaria, was coined by Linnaeus from the Latin convallis, a valley. The species name, majalis, refers to the month of May.

Where the meaning is written down

As the dictionary prints it
Return of happinessUnder the heading “Lily of the Valley” in Kate Greenaway, Language of Flowers, 1884.
As lists print it today
Returning happinessThe same reading, in today's wording.

Greenaway and Ingram's Flora Symbolica (1869) both give the same meaning, "return of happiness".

Is it poisonous?

Seriously toxic. It contains cardiac glycosides, and the ASPCA lists it as toxic to dogs, cats and horses, with vomiting, irregular heartbeat, low blood pressure, disorientation, coma and seizures; the RHS rates it toxic if eaten, for people and for pets.

Each finding above names who made it: the ASPCA's poisonous plant database, the Royal Horticultural Society's harm ratings, or a published report. This is general information and not veterinary advice — if an animal or a person has eaten part of a plant, ring a vet or a poison line rather than reading a website.
