P. zonale is native to South Africa but is a common ornamental flowering plant in various parts of the world today.
P. zonale was reportedly introduced to Europe at the turn of the eighteenth century by way of the Netherlands, where the garden in Leiden received seeds from the garden of the Dutch East India Trade Company in South Africa, and the plant was recorded to be growing in Amsterdam’s medicinal gardens by 1700.
In the USA, P. zonale has been present in cultivation since at least the time of Thomas Jefferson’s presidency (1801-180). He liked the plant and had it growing at both the White House and his home in Virginia, Monticello.
