Action Oak

The Action Oak partnership was launched at this year’s Chelsea Flower Show in London last May

Quercus wislizeni

In October 2017, I visited Palomar Mountain State Park, San Diego County, California to collect acorns of the interior live oak, Quercus wislizeni (Section Lobatae), for an investigation of oak hybridization at that location. Following the first day on site, while reviewing the day’s leaf samples, acorns, and photographs, a chance photo with an oblique view suggested that one individual Q. wislizeni bore yellow or golden hairs on the abaxial leaf surface.
