Flowers that change colour? That's what you can expect from hydrangea 'Jewel' (Hydrangea macrophylla). The 'Jewel' grows blue and green flowers. Over the course of the seasons, the colour changes from blue to purple to deep green. An ever-changing appearance! You can plant the hardy hydrangea all year round, provided temperatures have not dipped below freezing. The flowers bloom in the summer.
Pruning is not necessary. Unless the bush becomes too large. Plant the hydrangea in partial shade. The soil should be kept damp. Give them extra water during dry periods.
For months of enjoyment!
