Seeds that pop!
Tucked away behind the Cedrus knoll in the Arboretum’s Pinetum is the Euonymus europaeus ‘atrorubens’. At this time of year it is showing off its colorful seed pods, which hang all over the defoliated branches. A plant that has pink and orange fruits really catches your eye when you pass by.
This shrub is native to Europe and Western Asia and its common names are Spindle Tree and Cat Tree.

“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.
But this means it doesn’t contribute to English holly’s invasiveness in the Pacific Northwest.
Old cultivar in England, first reported in 1662 (Galle).
Specimen is located in the Eurasian clade (family), W. berm, of the Ilex Collection.
