Nepeta curviflora, commonly known as Syrian catnip, is a herbaceous flowering plant native to the Middle East.

[3] Nepeta curviflora is native to the far eastern coastal regions of the Mediterranean, namely Israel, Palestine, Lebanon and Syria.

[1] It inhabits Phrygana and Mediterranean woodlands, notably within the montane regions of Mount Hermon.

The two are differentiated by their flower colors, with N. italica presenting white while N. curviflora appears blue.

Although the location is not explicitly specified, scholars suggest that this tradition was practiced in the Jerusalem area, possibly as a Karaite rather than a rabbinic custom.
