There's a soldier's prayer that goes,   "Stay with me, God. The night is dark, The night is cold: my little spark Of courage dies. The night is long; Be with me, God, and make me strong.   Dark. Cold. Long.   It's easy to get so excited about the first nice days of spring.   "It was 80 degrees today!"   "It's going to be above 70 all next week!"   Well, hold your horses. You're forgetting about those nights. Remember?   Dark. Cold. Long.   No fun for tender transplants. Over in the FB group for listeners of the show, listener Denise Pugh shared an awesome Facebook Live session put on by one of the best: Lisa Mason Ziegler from The Gardener's Workshop. In the video, Lisa mentions the secret to successful transitioning of transplants from indoors to outdoors - the secret is consistent nighttime temps of 60 degrees or higher.   She's got a ton of other sage pieces of wisdom as well for growing warm weather crops - so head on over to the Daily Gardener Community on Facebook and check out the replay.  In the meantime, remember to curb your enthusiasm about those first lovely warm days of spring. Save the real celebration for the arrival of warm nights.     Brevities   #OTD On this day in 1863, botanist, physician and member of the U.S. House of Representatives, William Darlington died.     Like eminent botanists John Bartram, Humphry Marshall, and William Baldwin, Darlington was born in Pennsylvania as a Quaker.  A native of West Chester, he received his medical degree from the University of Pennsylvania in Philadelphia. As a student, Benjamin Barton, the author of the first American botany textbook, encouraged his interest in botany.   After an appointment as a surgeon for an East India merchant, Darlington traveled to Calcutta.  A year later, when he returned from India, he married Catharine Lacey, the daughter of a distinguished Revolutionary War General. An abiding counselor and partner to William, they would be together for forty years; having four sons and four daughters.  Their oldest son Benjamin Smith Barton Darlington and their youngest son William Baldwin Darlington were both named in honor of fellow botanists.   1826 was a big year for Darlington. He organized and presided over the Chester County Cabinet of Natural Sciences and he published his first edition of "Florula Cestrica," his catalogue of plants in West Chester.   An archivist, Darlington worked to preserve correspondence and documents of Humphry Marshall and John Bartram; he compiled them, along with illustrations of their homes, under the title of "Memorials of Bartram and Marshall." In 1853, the botanist John Torrey named a new and remarkable variety of pitcher-plant found in California  for Darlington, calling it  Darlingtonia Californica. He had been similarly honored but Augustin de Candolle who named a genus after him.  Darlington's large herbarium and works were bequeathed to the Chester County Cabinet of Natural Science. He was buried in the Oaklands Cemetery, near West Chester. An epitaph in Latin is inscribed on his stone marker, written by Darlington some twenty years before his death: "Plantae Cestrienses, quas dilexit atque illustravit, super tumulum ejus semper floreant" or May the plants of Chester, which he loved and documented, forever blossom over his grave. And, Darlington's tombstone is crowned with a relief of Darlingtonia californica.   #OTD It's the birthday of Thomas Grant Harbison born in 1862.   Harbison was a self-taught in botanist earning advanced degrees including a PhD by correspondence - a fairly novel concept in the late 1800s.    In 1886, Harbison and a friend created their own version of Survivor. They followed forest and mountain paths through Virginia, North and South Carolina, and Georgia. Cutting themselves off from civilization, they allowed themselves only five items for daily living: a wool en blanket, a rubber poncho, a tin bucket, a bag of wheat, and a tin of brown sugar. Their only other indulgence was a copy of
