(March 13 – 20, 2017)
1) Cornus mas Cornelian Cherry
- A native of Europe, C. mas has been cultivated for centuries in Britain. Flowers are produced in February and March on the leafless stems in short-stalked umbels from the joints of the previous year’s wood.
- Oblong-ellipsoid, fleshy, bright red fruit are produced in late summer, and are edible when ripe.
- Found throughout the Arboretum, these shrubs or small trees are easily identified at this time.
2) Corylopsis spicata Winter Hazel
- A native of Japan, C. spicata is an open, spreading shrub bearing yellow flowers in slender, pendent racemes.
- Located within the Witt Winter Garden.
3) Prunus ‘Okame’
- This cultivated variety (P. campanulata x P. incisa) has begun to show its beautiful, carmine-pink flowers.
- Located along the east side of Azalea Way at the south end of the Lilacs Collection (Bed ‘H’).
4) Rhododendron mucronulatum
- A dwarf to medium-sized deciduous azalea, R. mucronulatum produces flowers very early in the season. It is abundant in Korea, where it forms the undergrowth of larch forest on volcanic soils.
- Scattered throughout the Arboretum, the pink blossoms certainly draw one’s attention at this time.
5) Ribes sanguineum ‘King Edward VII’
- A native of western North America, this flowering currant always produces attractive flowers, never failing to blossom well.
- Located along the southern trail of the Woodland Garden, between the eastern pond and the wooden bridge.
