Chestnut blight (Diaporthe parasitica Murrill) was first discovered in the Bronx Zoo in 1904. By 1911 the headline in The New York Times read – “All Chestnut Trees Here Are Doomed”.

Posted by Hugh on October 31st, 2012
Blue mist spirea or bluebeard (Caryopteris x clandodensis) is not commonly planted in U.S. landscapes. In mid- to late- summer, pale blue flowers open above the gray-green foliage. Leaves and stems are mildly aromatic to the touch. There are now several good hybrid forms, thanks to plant breeders’ efforts to improve garden performance. Caryopteris (I prefer this name) grows in average soil, […]
