Hydrangeas have various shapes and are categorized into groups. The proper name for this plant is:

Hydrangea macrophylla Mophead has large round flowers from July to September (the most popular)
Hydrangea macrophylla Lacecap which is a flat flower head made up of a central cluster of small blooms
Hydrangea arborescens 'Annabelle' and family which is a showy shrub of huge round white blooms
Hydrangea quercifolia Oakleaf which has large leaves that usually turn orange, red and yellow in fall
Hydrangea paniculata PeeGee and family with cone shaped flowers
Hydrangea petiolaris which is a climber
Hydrangea aspera 'Villosa' is a Lace-cap with blue flowers
Hydrangea Florist or French are grown in a controlled environment with earlier blooms


The pink and blue Hydrangeas are hardy to zone four. The Annabelle is hardy to zone three and the best update I can provide is the development of another Annabelle which is pink. The proper name is: Hydrangea arborescens 'Invincibelle Spirit'. To learn more about this plant please Click Here.

Florist Hydrangeas vs. Outdoor Hydrangeas

The Florist Hydrangeas (also known as French Hydrangeas) are grown in a controlled environment and forced to bloom earlier than outdoor Hydrangeas. In late winter nurseries stock Hydrangeas that have been grown in greenhouses. They are usually available until spring and when using indoors they require bright, indirect light and must be kept evenly moist at all times. When the weather conditions are correct for planting you must cut off the old blossoms and plant outdoors preferably in a northern or eastern exposure. This will protect the plant from the hot sun and drying winds. Don't be discouraged if the plant does not survive the winter as they are confined to a small pot and the root system is not well developed thereby reducing their hardiness for surviving the winter months.

Outdoor Hydrangeas bloom later than Florist Hydrangeas. They are available in late spring. Outdoor Hydrangeas are not grown in a controlled environment therefore upon purchase you may plant immediately.
