Should you plant in the Fall? It depends what region you live in, what month in fall, and what species you’re planting. If you live in the mid-Atlantic, coastal New England, or Southeastern U.S., fall is an excellent time to set most hardy plants. Most (not all) trees, shrubs, perennials, […]

Vanilla Strawberry™ hydrangea (Hydrangea paniculata) is a new peegee hydrangea selection introduced from France and it is really catching on with U.S. gardeners (USDA hardiness zones 4-9). This exceptionally cold hardy hydrangea blooms from late June thru early September. Blooms are enormous and stand upright. Following a heavy summer shower, saturated floral trusses temporarily bow down under their sheer weight, but gradually recover. Flower color […]

The introduction of Endless Summer® hydrangeas in the 1990’s got gardeners excited about growing mophead hydrangeas (Hydrangea macrophylla) again. Mophead hydrangeas bloom both on old wood in the spring and again on new wood in mid-summer. Flowers have either a blue/pink color depending on the pH of the soil. Endless Summer hydrangeas bloomed […]

In the Southeastern U.S. region, wildly fluctuating temperatures this winter will likely destroy or delay spring and summer blooming on bigleaf (mophead) hydrangeas (Hydrangea macrophylla) (USDA hardiness zones 6 – 9). Other hydrangea species, such as smooth hydrangea (H. arborescens), panicle hydrangea (H. paniculata), and oakleaf hydrangeas, should not be affected. Bigleaf hydrangeas are […]

Mophead hydrangeas (Hydrangea macrophylla), the blue/pink flowering species, have been the gardening rage since the early 1990’s. Endless Summer® hydrangea started a wave of new repeat blooming (remontant) cultivars. They bloom on both new season’s as well as old wood from the previous year. These hardier cultivars extended the flowering time by 8 to 10 more weeks and bloomed in cooler climates formerly unable to […]
