Appointed to the King's garden in Paris, Sebastien loved organizing and cataloging plants. Biographical accounts say Sebastian showed a passion for plants from the age of five. His masterpiece, forty years in the making, Botanicon Parisienne, was a book about the flora of Paris. It wasn't published until five years after his death. Sebastian's work on plant sexuality inspired generations of botanists and set the stage for Linneaus to develop his sexual system of plant classification. Linnaeus used the male stamens to determine the class and the female pistils to determine the order. And like Sebastion, Linnaeus often compared plant sexuality to that of humans. Linnaeus wrote, Love even seizes... plants... both [males and females], even the hermaphrodites, hold their nuptials, which is what I now intend to discuss. Sebastian caused a sensation at the Royal Garden in Paris on June 10, 1717. On that day, he presented a lecture titled, Lecture on the Structure of the Flowers: Their Differences and the Use of Their Parts. He began by reinforcing the idea that the flower is the most essential part of a plant - essential to reproduction - and then he began to lead his scientific colleagues into a deep dive on plant sexuality - at six in the morning, no less. Before Sebastian's lecture, the topic of sex in the plant world had only been touched on lightly, allowing flowers and blossoms to maintain their reputation as pure, sweet, and innocent. Today, we can imagine the reaction of his 600-person audience as he began using fairly explicit language and the lens of human sexuality to describe the sex lives of plants. A 2002 translation of Sebastian's speech was presented in the Huntia - a Journal of Botanical History. Sebastian started his lecture with these words, Perhaps the language I am going to use for this purpose will seem a little novel for botany, but since it will be filled with terminology that is perfectly proper for the use of the parts ... I intend to expose, I believe it will be more comprehensible than the old fashioned terminology, which — being crammed with incorrect and ambiguous terms [is] better suited for confusing the subject than for shedding light on it. Sebastian's discussion of the plant embryos was rather poetic: Who can imagine that a prism with four faces becomes a Pansy;  a narrow roll, the Borage;  a kidney, the Daffodil;  that a cross can metamorphose into a maple;  two crystal balls intimately glued to each other, [Comfrey], etc.?  These are nevertheless the shapes favored in these diverse plants by their lowly little embryos.   1742 On this day, Horace Walpole wrote to Horace Mann, in part describing his visit to Ranelagh ("Ron-ah-lay") Gardens in Chelsea. Ranelagh had opened just two days prior, and it was one of several pleasure gardens opened around this time. Horace wrote,  Today calls itself May the 26th, as you perceive by the date; but I am writing to you by the fireside, instead of going to Vauxhall. If we have one warm day in seven, "we bless our stars, and think it luxury."  And yet we have as much waterworks and fresco diversions, as if we lay ten degrees nearer warmth.  Two nights ago Ranelagh-gardens were opened at Chelsea; the Prince, Princess, Duke, much nobility, and much mob besides, were there. There is a vast amphitheatre, finely gilt, painted, and illuminated, into which everybody that loves eating, drinking, staring, or crowding, is admitted for twelvepence.  The building and... gardens cost sixteen thousand pounds.  Twice a-week there are to be ridottos... [entertainment] for which you are to have a supper and music. I was there last night, but did not find the joy of it. Vauxhall is a little better; the garden is pleasanter, and [
