He was looking for a route to the west, and he found it. He discovered parts of North America on behalf of Henry VII of England. And in case you're wondering why we're talking about John Cabot today, it's because of the climbing rose named in his honor. And it's also the rose that got me good. I got a thorn from a John Cabot rose in my knuckle and ended up having surgery to clean out the infection about three days later. It was quite an ordeal. I think my recovery took about eight months. So the John Cabot Rose - any rose - is not to be trifled with.   1519 Leonardo da Vinci, the mathematician, scientist, painter, and botanist, died. Leonardo once said, We know more about the movement of celestial bodies than about the soil underfoot.   He also wrote, The wisest and noblest teacher is nature itself.   And if you're spending any time outdoors, we are learning new lessons in spring. Isn't that the truth? There's always some new development we've never encountered - and, of course, a few delights. Leonardo continued to study the flower of life, the Fibonacci sequence, which has fascinated them for centuries. You can see it in flowers. You can also see it in cell division. And if you've never seen Leonardo's drawings and sketches of flowers, you are missing a real treat, and I think they would make for an awesome wallpaper. Leonardo once wrote about how to make your own perfume. He wrote, To make a perfume, take some rose water and wash your hands in it, then take a lavender flower and rub it with your palms, and you will achieve the desired effect. That timeless rose-lavender combination is still a good one.   I think about Leonardo every spring when I turn on my sprinkler system because of consistent watering. Gives such a massive boost to the garden. All of a sudden, it just comes alive. Leonardo said, Water is the driving force in nature.   The power of water is incredible, and of course, we know that life on Earth is inextricably bound to water. Nothing grows; nothing lives without water. Leonardo was also a cat fan. He wrote, The smallest feline is a masterpiece.   In 1517 Leonardo made a mechanical lion for the King of France. This lion was designed to walk toward the king and then drop flowers at his feet. Today you can grow a rose named after Leonardo da Vinci in your garden. It's a beautiful pink rose, very lush, very pleasing, with lots of lovely big green leaves to go with those gorgeous blooms. It was Leonardo da Vinci who wrote, Human subtlety will never devise an invention more beautiful, more simple, or more direct than does nature because in her inventions, nothing is lacking, and nothing is superfluous.   1803 On this day, Napoleon and the United States inked a deal for the Louisiana Purchase and added 828,000 square miles of French territory to the United States for $27 million. This purchase impacted the Louis and Clark Expedition because they had to explore the area that was bought in addition to the entire Pacific Northwest. To get ready for this trip, Meriwether Lewis was sent to Philadelphia. While there, he worked with a botanist, a naturalist, and a physician named Benjamin Smith Barton. He was the expert in Philadelphia, so he tutored Meriwether Lewis to get him ready because Lewis did not know natural history or plants. So he needed to cram all this information to maximize what he saw and collected. Now, in addition to all of this homework, all of this studying about horticulture and botany and the natural world, Meriwether made one other purchase for $20. He bought himself a big, beautiful Newfoundland dog, and he named him Seaman. It's always nice to have a little dog with you while exploring.   1806 The garden writer
