Florigelia were popular in the seventeeth century. Often illustrated by eminent artists, the lavishly produced books catalogued the plants in a garden, or collected on an expedition. Who can afford to produce such a book today? A prince, of course. His Royal Highness, Prince Charles of Wales, who sponsored The Highgrove Florilegium, a collection of plants in the royal garden, and one of the most expensive books of modern times.
The Temple of Flora is perhaps the most famous florilegium or book of flowers from the golden age of botanical illustration. It's a charming collection of deliberately idiosyncratic flower portraits that became the portrait of a nation.
