Pachystachys lutea
This plant can grow 100 to 150 cm in height and forms a spike of about 10 cm in length at the tip of the stem.  Heart-shaped yellow bracts regularly line up on top of one another in 4 rows and white labiate flowers project out and bloom among them.  The bloom is short-lived but bracts do not fade for a few weeks to keep its beautiful appearance.
The genus name came from the Greek words Pachys + Stachys (meaning thick and spike); it does not mean that it is endemic to Pakistan.
The species most commonly used for ornamental purposes is P. lutea and when saying just Pachystachys, it refers to P. lutea.  However, P. coccinea which is endemic to Guyana and has green bracts and red blooms is also used for ornamental purposes and is called Beni-sango-bana (meaning red coral bloom) in Japan.  The lutea also has another name Ukon-sango (meaning turmeric coral) in Japan.
