Etymology.
"Helianthus" is derived from Greek, meaning 'sun-flower' ('heli' meaning 'sun', and 'anthus', as in 'anther', meaning 'flower'). As the large, yellow-gold heads of many species tend to follow the sun, the Italian-derived 'girare-sole', literally meaning 'turning sun', is also a cognate with 'Jerusalem', as in Jerusalem Artichoke.
"Nuttallii" is named for Thomas Nuttall (1786-1859), a grower of American plants at Rainhill in Lancashire, though he lived in Long Preston in Yorkshire.
"Parishii" is named for Samuel Bonsall Parish and William Fletcher Parish, California botanists.
