What does delphinia mean?
Delphinia is the plural form of delphinium, denoting members of a genus of striking flowering plants cultivated for their tall, elegant spikes of blue, purple, pink, or white blooms. Gardeners prize delphinia for adding vertical drama to borders and cottage gardens, though they demand rich soil, support against wind, and protection from slugs. The name traces back to the Greek word for dolphin, inspired by the resemblance of the flower bud to that marine mammal — a lineage it shares with the city of Philadelphia through the same Greek root meaning womb or brotherhood. Separately, Delphinia was the name of an ancient Athenian festival honouring Apollo Delphinios. In modern usage the word belongs chiefly to horticultural writing; the anglicized plural "delphiniums" is more common in casual conversation.
Plural of delphinium: perennial flowering plants of the genus Delphinium, bearing tall spikes of blue, purple, pink, or white flowers.
"The delphinia along the south wall reached nearly six feet by midsummer."
Often used in gardening and botanical writing; the regularized plural "delphiniums" is common in informal speech.
An ancient Greek festival held annually at Athens in honour of Apollo Delphinios.
"The Delphinia were celebrated in the spring month Mounichion with processions to Apollo's sanctuary."
This sense is restricted to historical and classical scholarship; when capitalized, Delphinia refers specifically to the festival.
Both plurals are accepted; "delphiniums" predominates in everyday usage, while "delphinia" lends a more formal or literary tone.
"Rows of delphinia framed the garden path in vivid blue."
The delphinium got its name because ancient Greeks thought the flower's bud resembled a dolphin — and it shares that root with the word 'Philadelphia', the 'city of brotherly love'.

Etymology of delphinia
The word derives from Latin delphinium, borrowed from Greek delphínion, a diminutive of delphís meaning dolphin, so named because the shape of the flower's bud was thought to resemble a dolphin. The same Greek root delphys (womb) underlies adelphós (brother), and thus Philadelphia. The Athenian festival Delphinia took its name directly from the epithet Apollo Delphinios.
