Also, looking at English tea culture on wikipedia...
"The first record of tea in English came from a letter written by Richard Wickham, who ran an
East India Company office in Japan, writing to a merchant in
Macao requesting "the best sort of chaw" in 1615.
Peter Mundy, a traveller and merchant who came across tea in Fujian in 1637, wrote, "
chaa — only water with a kind of herb boyled in it ".
[43][44] Tea was sold in a coffee house in London in 1657,
Samuel Pepys tasted tea in 1660, and
Catherine of Braganza took the tea-drinking habit to the British court when she married
Charles II in 1662. Tea, however, was not widely consumed in Britain until the 18th century, and remained expensive until the latter part of that period. British drinkers preferred to add sugar and milk to black tea, and black tea overtook
green tea in popularity in the 1720s.
[45] Tea smuggling during the 18th century led to the general public being able to afford and consume tea. The British government removed the tax on tea, thereby eliminating the smuggling trade by 1785.
[46] In Britain and Ireland, tea was initially consumed as a luxury item on special occasions, such as religious festivals, wakes, and domestic work gatherings. The price of tea in Europe fell steadily during the 19th century, especially after Indian tea began to arrive in large quantities; by the late 19th century tea had become an everyday beverage for all levels of society.
[47] The popularity of tea also informed a number of historical events – the
Tea Act of 1773 provoked the
Boston Tea Party that escalated into the
American Revolution, and the need to address the issue of British trade deficit caused by the demand for Chinese tea led to a
trade in opium that resulted in the
Opium Wars.

It looks like there is plenty of opportunity for Yaupon to be introduced to England before Catherine of Braganza makes Chinese tea fashionable, assuming her marriage isn't butterflied away... or she adapts to already present Yaupon Tea.
