The hydrangeas bloom in May and June. Magnolia Landscape Supply has the traditional hydrangeas for the shade and we also have the Limelight and Phantom hydrangea that are good for full sun.
Hydrangeas grow best in moist, well-drained soil. Most hydrangeas benefit from some shade, especially in hot climates. Bigleaf, oakleaf and smooth hydrangeas will usually perform well on the north side of a house or planted at the edge of a woodland (see image at right). As discussed earlier, growing hydrangeas in deep shade is not necessary and can greatly reduce flowering.
The amount of sun that hydrangeas can tolerate depends on species, climate and availability of water. Panicle hydrangea tolerates more sun than do other species. Plants grown in hot climates require more shade than do those grown in the colder limits of adaptation. In southern climates, providing frequent and adequate watering will allow hydrangeas to tolerant more sun than if they were subjected to moisture stress.
