Hydrangea arborescens ‘Annabelle’
It opens green, turns white and then turns green again.
The word ‘hydrangea’ comes from the Greek ‘hydor’ meaning ‘water’ and ‘angos’ meaning ‘jar’.
Most species are deciduous, and we have a wide variety in our Garden, with a special hydrangea bed midway along the Rhododendron Walk. The flower heads come in various shapes: the mophead blooms are like big pompoms whereas the lacecaps have flat, unshowy, albeit fertile, flowers in the centre and bigger outer flowers which are sterile. More about types of hydrangeas. The most common colours of blue, pink and purple depend on the ph of the soil and can change over time. The language of flowers gives the hydrangea several meanings. Hydrangeas are moderately toxic if eaten, with all parts of the plant containing cyanogenic glycosides.
