Today we remember the kind Harvard botanist who was a friend of Darwin. We'll also learn about the botanist who specialized in South American flora and found the Cinchona tree: the source of quinine. We salute the pioneer of the study of allelopathy - when one plant species releases chemical compounds that affect another plant species. We also recognize the man who transformed the springtime landscape at the beautiful Magnolia Gardens. We honor the first woman to attend Cornell University's school of forestry. Today's Unearthed Words feature a poem called The Sleep of Seeds. We Grow That Garden Library™ with a book about the "Science, Art, and Joy of Propagation"; learn how to grow whatever you want, whenever you want. And then we'll wrap things up with a delightful story about a horticulture teacher.

Successfully drying one of your favorite flowers is such a joy. Some flowers look even better when they are dried. There are many options for drying flowers; air drying is the simplest. Then, of course, there's pressing. If you've never tried sand drying a bloom, you should give it a shot. Just fill a microwave-safe container with a layer of silica sand. Put the flower on top of the sand and then bury the bloom in the sand. Place the bloom along with a cup of water in the microwave. Heat in microwave in 30-second increments. Your flower should be dried in 2-3 minutes. Another step you can take in your flower-drying hobby is to prepare a spot in your garden shed, garage, pantry, or kitchen for drying flowers. Repurpose a pot rack or do something simple like string some twine between some eye hooks. Sometimes just creating space can inspire you to take some cuttings and bring beautiful blooms indoors. One of my favorite pictures from my garden is a single row of hydrangea cuttings drying upside down in my kitchen. Bliss.   Alright, that's it for today's gardening news.

Cornelius pioneered the study of allelopathy ("ah-la-LOP-OH-thee"). Allelopathy occurs when one plant species releases chemical compounds that affect another plant species. Most gardeners know that black walnut is an example of allelopathy. In addition to the roots, black walnut trees store allelopathic chemicals in their buds, in the hulls of the walnuts, and their leaves.   1917  Today is the birthday of John Drayton Hastie of Magnol
