Plants of the Week: January 26

The dinner-plate-sized inflorescence of Hydrangea arborescens ‘Haas’ Halo’ is particularly appealing with a fresh dusting of snow. The magnitude of each bloom, often up to 14” across, never fails to capture attention. Sturdy stems keep the flowers upright and large leaves give the shrub a full and vigorous look. As winter precipitation falls and cold winds blow there is no worry whether flower buds will be killed. H. arborescens blooms on new wood thus guaranteeing a spectacular floral display each season. We hope to feature Hydrangea arborescens ‘Haas’ Halo’ at the 2015 Scott Arboretum Plant Sale.  Photo credit: J. Coceano…

Plants of the Week: January 12, 2015

Pinus heldreichii anchors a corner planting around the Sproul Observatory building. Bosnian pine is native to dry limestone soils in mountain areas of the Balkans, Italy, and Greece where it grows to 60’ to 90′ tall. In cultivation the pine typically grows to 30’ to 40′ tall.  A slow-growing evergreen with stiff upright bundles of needles, dark green in color, P. heldreichii is tightly conical in youth, maturing to a more open habit with age. The species name honors Greek botanist Theodor von Heldreich (1822-1902). Pinus leucodermis is now considered to be synonymous with this species. Photo credit: J. Coceano…

Ideal for any garden on a small property with a long descending walkway,  dwarf cultivars of the beloved pine tree have been moved into the Winter Garden. Pinus strobus ‘Minuta’ …
