“Teller Blue” is considered one of the best blue-coloured Hydrangeas. In order to best achieve these blue colours, plant in a more acidic soil. As such, this plant will produce deep indigo shades of blue flowers, which range from 15 to 20 cm in diameter. In a more alkaline soil, the petals will tend towards a lighter blue to pink shade. The broad, flattened flower clusters form in a lacecap and are composed of groupings of florets which vary from being only decorative to fertile. It is a compact deciduous shrub with large dark green leaves. This shrub has a habit to grow in an oval or rounded shape. It is hardy in the UK and can tolerate most extreme winter temperatures down to -10 C. Hydrangeas prefer moist soils, so if they are kept in the sun, a planter’s box or tub, they should be regularly watered. They do well in partially shaded areas. Like many Hydrangeas, they are good to prune after the flower season or at the beginning of spring before significant growth. However, they can also be aggressively pruned before the start of the season if the plant has become out of shape. Pot Size: 9cm Plant Height (Inc.
