Coming Attractions for 2014 in Horticulture and Plant Records

There is much to look forward to in 2014 for the University of Washington Botanic Gardens (UWBG) horticulture and plant records staff. It will be a rare year of “normality” between capital project implementations, the completed 2013 Pacific Connections Gardens (PCG) New Zealand (NZ) forest exhibit and the looming 2015 multi-use trail. Our resources will be focused on smaller scale deferred maintenance projects of several gardens and plant collections, catching up with plant labeling and mapping of our Pacific Connections Gardens and embarking on a few recently awarded grants.

“Berry Best from Hollywood”
1)   Ilex aquifolium   ‘Ferox Argentea’   (Variegated Porcupine Holly)

This “Punk” star is a sterile male with spiny leaves, but obviously no berries.

Old cultivar in England, first reported in 1662 (Galle).
Specimen is located in the Eurasian clade (family), W. berm, of the Ilex Collection.
