1) Arbutus unedo (Strawberry tree)
- Selected cuttings from the Washington Park Arboretum (October 3 – 16, 2011)
- Evergreen tree native to the Mediterranean and southwest Ireland, specifically the islands
and shores of the Lakes of Killarney, where it attains its largest (40 ft. or more in height)
- The flowers of A. unedo arrive late in the season, and are followed by the globose
strawberry-like fruits that are orange-red in color.
- This specimen is located near the Graham Visitors Center between the courtyard and parking
2) Euonymus hamiltonianus ssp. sieboldianus
- Commonly known as “spindle” trees, members of the genus Euonymus are mostly tree-like
deciduous shrubs native to Asia. They are cultivated not for their flowers, but for their
beautiful fruits, which split open in the fall to reveal colored seeds and seed coats (arils),
adding to the effect when the cells burst. The almost spherical pink fruits of this specimen
contain blood-red seeds with orange arils.
- Located in the Pinetum, just south of the footbridge.
3) Mespilus germanica ‘Macrocarpa’ (Open-arse)
- The only species of its genus, M. germanica is a low deciduous tree of crooked habit. The
five-celled fruits are apple-shaped and brown and when ripe, yield a mushy sauce which could
seemingly explain the European vernacular given to this tree. Located in the Holly wedge
across the Boulevard from the Boyer Lot, this specimen sometimes flowers again in early
October, adding to its uniqueness.
4) Pyracantha coccinea (Scarlet firethorn)
- Dense, thorny shrub with bright berries. Located along Arboretum Drive, just north of
5) Viburnum opulus (European cranberry bush)
- Deciduous shrub with maple-like leaves and bright red fruit. Located within the Viburnum
