They also have a high rainfall requirement and will not tolerate drought.

Etymology
The genus was named in 1753 by Carl Linnaeus to honour John Stuart, 3rd Earl of Bute. Owing to a transcription error, Linnaeus was given the name as 'Stewart', and consequently spelled the name "Stewartia" (and continued to do so in all his subsequent publications). Some botanists and horticulturists, mainly in the pastL'Héritier de Brutelle, C. L. (1785). ''Stirpes Novae aut Minus Cognitae'' (cited by W. J. Bean 1980).Siebold, P. F. von, & Zuccarini, J. G.
