Lacecap hydrangea: Hydrangea serrata Blue Willow

Grown from seed collected in the mountains of Korea by plant explorer Dr. Richard Lighty, 'Blue Willow' is unusually cold tolerant. Because most hydrangeas form the buds for next year's flowers before winter, their bloom is vulnerable to cold. 'Blue Willow,' usually resists this sort of damage and is a very reliable bloomer that bears metallic-blue, lacecap-type flower heads. Somewhat slower growing than other lacecaps, it is naturally dwarfed and compact.

did you know?

The name hydrangea is derived from two Greek words: meaning "water," and meaning "vessel," because the vase-shaped seed pods of hydrangea resemble water vessels.

general maintenance:

In early spring, deadhead, taking care not to damage the emerging, swollen, green buds, and remove any dead branches, or if necessary, old growth, making all cuts at the base of the plant.

pests/diseases:

Aphids, scale insects, whiteflies, and honey fungus may occur.

controls:

Regularly hose off aphids with a directed stream of water, or apply insecticidal soap, following label directions. To control scale, remove with a cotton swab dipped in alcohol, and remove infested leaves. Spray whiteflies with insecticidal soap, following label directions. To discourage honey fungus, remove and destroy diseased plants.

how to sow/plant:

Start with new plants, rooted softwood cuttings, or fall divisions. Plant in spring or fall; choose a partly shady site with moist, well-drained soil, and amend with well-rotted manure or compost. Set plants at same depth they were in pot, spacing at distance equal to plants' mature spread. Water upon planting, and mulch to conserve moisture.

water and fertilize:

Monitor soil moisture all season. In dry periods, hydrangea leaves become distinctly wilted; water immediately when this happens. In spring and after flowering, feed with a balanced fertilizer, following label directions.

garden hint:

With many hydrangeas, flower color is often determined by the soil pH. To encourage blue flowers, lower pH by amending the soil with sulfur, peat, potash, or sulfate before planting; to encourage pink flowers, raise pH by adding lime to soil, following label instructions.
