    The North American Rock Garden Society (NARGS) will present Troughs Coast to Coast: Celebrating Gardens with Rock Plants in Containers, a virtual International Study Day, on Saturday, November 14th at 2 PM EST. The cost is $25 for NARGS members; and $50 (which includes the pleasure of joining NARGS) for nonmembers. Troughs Coast to Coast is being held as a live online Zoom event but your ticket will allow you to view the event later or revisit any part of it any number of times. Presentations on how to build, plant, and display troughs will be made by horticultural authorities from disparate gardens as that from the roof of the NYC Rockefeller Center, the (Tilden Park) Regional Parks Botanic Garden (Berkeley, CA), the Millstream Garden Award 2020 recipient and Philadelphia Flower Show medalist, and the Denver Botanic Gardens. Plus design, plant choice and care at Wrightman’s Nursery. Questions? email nargspres [at] gmail [dot] com

    Lost Horizons' stock is available at 20% off. Larry Davidson, the owner, has informed us that the nursery  will be open this fall from Wednesday to Sunday, 10AM - 5PM, for as long as the weather holds. If the weather turns nasty please call ahead to make sure they're open. They still hope the nursery will sell (glass quarter full) but if not it will be opening in the spring to sell off remaining stock.  http://www.losthorizons.ca
