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.

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’ was selected for its low mounded habit. This cultivar resembles the stately white pine of the northeastern forest without the concerns of weak wood collapsing on your car/house in …
