Today we celebrate the Swiss botanist who started a botanical Dynasty and the man who coined the term osmosis. We’ll learn about the American landscape architect who made England his home and cheered on so many gardeners with his book Successful Town Gardening. Today’s Unearthed Words feature words about winter. We Grow That Garden Library™ with a book about hunting for medicinal plants in the Amazon. I’ll talk about a garden item to help you get growing and then we’ll wrap things up with the early spring warm-up of 1931 - it was extraordinary. But first, let’s catch up on a few recent events.   Subscribe Apple | Google | Spotify | Stitcher | iHeart   Curated Articles American Gardens: An American Garden In Bath American gardens: an American garden in Bath by Gardens Illustrated @gdnsillustrated What is an American garden?

His seven-volume monumental work, Prodromus, was an effort to characterize all of the plant families and establishing the basis for the science of botany. He only finished two volumes. Augustin’s Candolle descendants would finish Prodromus after extensive and detailed research. His famous son, Alphonse, was born the year Linnaeus died. In 1855, Alphonse was awarded the Linnean gold medal. Augustin’s grandson, Casimir, was devoted to the study of the pepper plant family or the Piperaceae ("PIE-per-aye-see-ee"). The most commonly-known species in the family is Piper nigrum ("PIE-purr NYE-grum") - a flowering vine that gives us peppercorns that are ground to become black Pepper. The biggest consumer of Pepper, at almost 20% of the world’s total Pepper crop, is the United States. During the middle ages, pound for pound peppercorns was worth more than silver. Augustin de Candolle’s great-grandson, Richard Émile, was also a botanist. He died unexpectedly at the age of 51. After his death, the enormous Candolle family herbarium and Library - built over four generations was donated to the city of Geneva. Augustin’s great living legacy is the Botanical Garden of Geneva.   1847Today is the anniversary of the death of the French botanist and physiologist Henri Dutrochet. After studying the movement of sap in plants in his home laboratory, Dutrochet discovered and named osmosis. Dutrochet shared his discovery with the Paris Academy of Sciences on October 30th, 1826. Like the cells in our own human bodies, plants don’t drink water; they absorb it by osmosis. Dutrochet also figured out that the green pigment, chlorophyll, in a plant is essential to how plants take up carbon dioxide. Photosynthesis could not happen without chlorophyll, which helps plants get energy from light. And chlorophyll gives plants their color. Have you ever asked yourself why plants are green? Long story short, chlorophyll reflects green light, which makes the plant appear green. Dutrochet was a true pioneer in plant research. He was the first to examine plant respiration, light sensitivity, and geotropism (How the plant responds to gravity, ie, roots grow down to the ground.) The upward growth of plants against gravity is called negative geotropism, and downward growth of roots is called positive geotropism. The plant part that responds to positive geotropism is at the very end of the root, and it is called the roo
