Hydrangeas: Why Flowers Turn Green and How to Build a Candle Centerpiece

Hydrangeas often shift to a green hue as the flower heads mature, with pigments fading and seasonal light, soil conditions and specific varieties influencing the change. The green stage is a natural part of the plant’s life cycle rather than a sign of disease.

A DIY guide outlines four methods for creating a lasting hydrangea crown around a candle, including using a recycled kouglof mold, pre‑saturated floral foam rings, elastic‑bound photophore holders, and cardboard rings. The most reliable technique uses hydrophilic floral foam kept moist for a week‑long display, while other methods suit shorter‑term occasions.
