About the name
Acacia is Greek akakia, from ake, a thorn — the tree is named for its spines. A separate Greek word akakia means guilelessness or innocence, and the two have been conflated for so long that the flower-language meaning of the acacia is now innocence.
The tree carries real weight elsewhere: acacia wood builds the Ark of the Covenant in Exodus, and the species dominates the African savanna. As a given name it sits outside the US top 1000.
Cass is the short form that hides it entirely. Three syllables want one (Acacia Wren, Acacia June). On our vibe map it is Nature-Inspired with Boho colour.
