How to recognise Blue Verena hydrangea, when it is in season and how to keep it fresh.
Strip all foliage below the waterline and smash or split the stem end to improve water uptake. Give deep, cool water and keep in a humid environment; mist the heads if they start to wilt. Recut stems under water and dip the cut end briefly in boiling water or alum if they droop. Keep away from ethylene sources and draughts.
