Birth flower

Holly

Ilex aquifolium. In the language of flowers, as lists print it today, it stands for defence. Kate Greenaway's dictionary of 1884 gives it another: “Foresight”. It is a custom of sentiment, not a scientific or official designation.

The plant itself

Habitshrub
Heightup to 15 m as a tree, usually far less as a hedge
FlowersMay to June, with the berries ripening from late autumn

Holly is dioecious: a plant is either male or female, and only a female bears berries, so a berryless holly is not failing but is simply male. The prickles are also not uniform — leaves higher up the tree, out of a browsing animal's reach, are often smooth-edged.

Where the names come from

Holly, from the mid-1400s, is a shortening of the earlier holin, from the Old English holegn or holen. It is related to Celtic words such as the Welsh celyn, and all probably go back to a root meaning to prick, for the prickly leaves. The genus name, Ilex, is the Latin for the holm oak. The species name, aquifolium, is from the Latin aquifolius, having prickly or pointed leaves, from acus, a needle, and folium, a leaf.

Where the meaning is written down

As the dictionary prints it
ForesightUnder the heading “Holly” in Kate Greenaway, Language of Flowers, 1884.
As lists print it today
DefenceA different reading from the entry quoted here; the note below says where it differs.

Greenaway's entry is simply "Holly — Foresight", and Ingram's Flora Symbolica (1869) gives the same. The "defence" printed today is in neither.

Is it poisonous?

The ASPCA lists holly, Ilex aquifolium included, as toxic to dogs, cats and horses through saponins, causing vomiting, diarrhoea and depression, though it rates the leaves and berries as of low toxicity. The RHS says the fruit is ornamental and not to be eaten, by people or by 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.
